Two Mighty bodies buy a ready Jaull-Fish on T4, and the three Body runes it recycles are the part no discount touches

Issue #397 (a slice of #200), 2026-10-18. Constructed, Duel (485). Rules version 2026-07-16. Card text verbatim from data/corpus_flat.txt; rules pasted from data/Riftbound-Core-Rules-2026-07-16.txt and data/Riftbound-Tournament-Rules-2026-07-16.txt. Read the unopposed clock for the baseline this is measured against.

Subject: jaull-fish-garen-rugged-mighty-discount, the Body ENGINE in which SFD-103 Jaull-Fish (E7 + 2 Body Power, M6) costs 2 Energy less for each Mighty unit you control, with OGS-007 Garen, Rugged as the printed-5 body that turns the discount on. The entry is right about its trap: [Shield] and [Assault] only count inside a combat, so a body that is a 5 only while defending counts as what it prints when the cost is read. It is right that 356.6 floors the Energy and never touches the Power. It misses two things. The discount also reaches [Accelerate]'s Energy, because additional costs are added before discounts are applied (356.2, 356.4, 356.4.f), so four Mighty bodies make a ready Jaull-Fish cost 0 Energy, not 1. And Garen is not the cheapest certain Mighty body: nineteen mono-Body units with printed Might 5 or more cost less than his E6 + 1 Body Power. Walked as a game, going first, against a Fury/Chaos Jinx deck that stacked its own battlefield, UNL-171 Galio, Indefatigable and VEN-088 Jayce, Hammer in Hand made two Mighty bodies, the Jaull-Fish came down ready on T4 for 4 Energy and 3 Body Power, and it walked into their battlefield beside Jayce and the Ramhound: 4 to 2 after their T4. Without it, the same turn spent on Garen holds and attacks nothing: 3 to 3. At full price it cannot be played on T4 at all. The bill comes in runes: three Body runes recycled on T4, so the line ends T4 with three runes on the board against the control's five, and 30.30% of rune orders cannot pay it on T4. The cheapest cards that break the turn are not answers to the discount. They take the attack's third body, the Ramhound, which leaves the attack two short: VEN-107 Decree of Discord returns it from your base on their T3 for one rune, recycled, and OGN-169 Gust returns it in the combat for one rune and no Power.

Why this line. scripts/sequence-pick.mjs --unplayed, re-run on 2026-10-18 at 1c031c2, reads 773 entries, 262 with forced-ordering language, 100 in the queue and 19 of them with no play, as the issue measured. The two picks are unchanged: this entry is rank 83, the second in the list. The other entry of this slice is rank 82, carnivorous-snapvine-rampage-tank-bypass, played in Galio alone deals no combat damage, so the Snapvine beats him by killing his partners and never by choosing him.

The third attackerSFD-159 Trusty Ramhound (Order, E2, M2)

The entry admits any of seventeen legends with Body in their pair. Might of Demacia is the one for this walk because its tag is Garen, so the entry's own body can be the Chosen Champion, 103.2.a.2: "Must be a champion unit with a champion tag that matches the tag on your Champion Legend." Garen, Rugged is tagged Elite, Garen and Demacia, and is not a Signature card (signature in data/cards.json). He starts in the Champion Zone, 103.2.a.1: "This will be placed in the Champion Zone at the start of the game." The legend's text plays no part in the line ("When you conquer, if you have 4+ units at that battlefield, draw 2."): no conquer here has more than one unit of yours at the battlefield.

Every card here is in the legend's domains, 103.1.b.1: "Cards included in your deck must abide by your Domain Identity." None is a Signature card, and none is in data/legality.src.json or marked [BANNED] in data/corpus_flat.txt.

The card text the play turns on:

2. What the discount counts, when, and what it can reach

Mighty is a state, read from current Might on the board. 708: "A Unit "is Mighty" as long as its Might is 5 or greater." 710: "Units on the board are evaluated according to their current Might." The entry cites 709, which is the event, "A Unit "becomes Mighty" at the moment its Might changes from being less than 5 to being 5 or greater."; the Jaull-Fish reads the state.

[Shield] and [Assault] are not current Might outside a combat. 814.1.c: "It is functionally short for "While I am a defender, I have +X [M]."" 807.1.c: "It is functionally short for "While I am an attacker, I have +X [M]."" Both designations come from a combat, 814.1.d: "Being a defender means the Unit has gained the Defender designation during Combat." The Jaull-Fish is played in your own Main Phase, where nobody is an attacker or a defender. So UNL-099 Towering Combatant (Body, E4, M3, "[Shield 2] (+2 :rb_might: while I'm a defender.)") counts as a 3, and Garen counts as his printed 5. The entry is right about this.

The count is read with the Jaull-Fish already on the chain, and nothing lets them act between. Playing a card starts by moving it, 354: "1. Move the card from its current zone to the Chain." 354.1: "This Closes the State." The cost comes two steps later, 356: "3. Determine Total Cost." In a Closed State only Reactions can be played, 309.1.a: "Only cards and abilities with the Reaction keyword can be played or activated in a Closed State." And they do not get priority until you pass it, 312.2.d: "When the turn is in a Closed State, they are the next Player in Turn Order, and the player with Priority passes." By then the cost is paid. So the board that counts is the board you start the chain with.

Play it first, or you open the window yourself. Your Main Phase is yours alone, 316.5.b: "This is denoted as a Neutral Open State, and only the Turn Player has the ability to play spells or activate abilities." Every card you play before the Jaull-Fish starts a chain, and a Reaction can answer on it, 813.1.c.1: "On Cards: "This can be played during Closed States on any player's turn."" The entry's second step, pumping a body with VEN-077 Tools of Empire before the Jaull-Fish, is an activated ability, and 377 puts that on the chain too: "Activated Abilities are repeatable effects with a cost. They follow a process of going onto the chain and resolving, similar to Playing a Card." That pump is a window for them, opened before the count. In this walk the only window on your T4 before the count is Jayce's own trigger, 383.3: "When a Condition is met, a Triggered Ability behaves like an Activated Ability and is placed on the Chain."

The discount reaches [Accelerate]. The total cost is built in order: 356.2, "Apply additional costs in any order.", then 356.4, "Apply discounts." [Accelerate] is an additional cost, 805.1.a: "Accelerate is functionally short for "As you play me, you may pay [1][C] as an additional cost. If you do, I enter ready."" A discount on the whole cost comes after, 356.4.d: "Discounts that apply to the total cost of a spell and not any one component of the cost must be applied after any discount that applies only to a component of the cost." And it may eat the additional cost, 356.4.f: "Discounts can reduce additional costs, including to 0." So the Jaull-Fish with [Accelerate] is 8 Energy and 3 Body Power before the discount, and each Mighty body takes 2 off the 8. The floor is 356.6: "Energy and Power costs can't be reduced below 0." The Power is untouched: the discount names only Energy, and 805.1.a.1 fixes the third Power's domain, "If the unit has one or more domains, the Power portion of the Accelerate cost can be paid only with a Power that matches one of the domains of the unit."

Mighty bodiesJaull-FishJaull-Fish with [Accelerate]
0E7 + 2 BodyE8 + 3 Body
1E5 + 2 BodyE6 + 3 Body
2E3 + 2 BodyE4 + 3 Body
3E1 + 2 BodyE2 + 3 Body
4E0 + 2 Body (1 Energy of discount wasted)E0 + 3 Body

Every Power is a rune off the board. A rune adds Energy by exhausting, 164.2.a: "[E]: [Reaction] — Add [1].", and Power only by leaving, 164.2.b: "Recycle this: [Reaction] — Add [C]." A rune exhausted for Energy can still be recycled for Power, so a cost of E4 + 3 Power is four runes, three of them recycled. They go to the bottom of the rune deck, 416.1: "Recycling cards is the action in which a player takes one or more cards from a specific zone and then puts it on the bottom of the corresponding deck." Going first, you channel your twelfth rune on T6, so a rune recycled on T4 does not come back before T7. The ready Jaull-Fish costs three Body runes at every Mighty count.

The runes, going first. You have 2, 4, 6 and 8 runes channelled by T1 to T4, less what you have recycled.

3. Their deck: Fury/Chaos Jinx

OGN-251 Loose Cannon (Fury/Chaos): "At start of your Beginning Phase, draw 1 if you have one or fewer cards in your hand." It fires once in the walk, on their T4. Its Chosen Champion is OGN-030 Jinx, Demolitionist (Fury, E3 + 1 Fury Power, M4): "[Accelerate] (You may pay :rb_energy_1::rb_rune_fury: as an additional cost to have me enter ready.) [Assault 2] (+2 :rb_might: while I'm an attacker.) When you play me, discard 2." She is played from the Champion Zone, 419.1.a: "By default, a player can only Play cards from their hand or their Chosen Champion zone." Their bodies are OGN-018 Noxus Saboteur (Fury, E3, M3; "Your opponents' [Hidden] cards can't be revealed here.", and you hide nothing), OGN-013 Pouty Poro (Fury, E2, M2, [Deflect]), OGN-016 Dangerous Duo (Fury, E3, M3; its [Legion] +2 expires at the end of their turn) and OGN-010 Legion Rearguard (Fury, E2, M2). Going second, they channel an extra rune on T1, 485.7: "The player going second channels an extra Rune from their Rune Deck during their first Channel Phase of the game." §5 names their answers.

4. The turns, going first

Body/Order against Fury/Chaos. Your battlefield is A, OGN-282 Monastery of Hirana ("When you conquer here, you may spend a buff to draw 1.", and nobody has a buff); theirs is B, SFD-210 Hall of Legends ("When you conquer here, you may pay :rb_energy_1: to ready your legend.", and neither legend has an exhaust ability to use). Your opening four are Trusty Ramhound, Galio, Jayce and the Jaull-Fish. Your draws are OGN-210 Daring Poro (T1), OGN-216 Soaring Scout (T2), SFD-167 Unsung Hero (T3) and SFD-099 Veteran Poro (T4). Their opening four are Noxus Saboteur, Pouty Poro, Dangerous Duo and Legion Rearguard. Their draws are OGN-171 Mystic Poro (T1), OGN-003 Chemtech Enforcer (T2), OGN-202 Jinx, Rebel (T3), and on T4 OGN-018 Noxus Saboteur (the legend's draw) and OGN-016 Dangerous Duo.

Their points: 0 after their T1, 1 after their T2, 2 after their T3, 2 after their T4. After your T3 it is 2 to 1; after their T3, 2 to 2; after your T4, 4 to 2; after their T4, 4 to 2.

Runes on your board at the end of each turn: 2, 3, 4, 3. On theirs: 3, 4, 6, 7.

Your hand, card by card: 5 after the T1 draw, 4 after the Ramhound; 5, then 4 after Galio; 5, then 4 after Jayce; 5 after the T4 draw, 3 after the Jaull-Fish and the Daring Poro (Soaring Scout, Unsung Hero, Veteran Poro). Garen stays in the Champion Zone. Theirs: 5 after the T1 draw, 4 after the Saboteur; 5 after the T2 draw, 3 after Jinx's discard (Mystic Poro and Chemtech Enforcer), 2 after the Pouty Poro; 3 after the T3 draw, 1 after the Duo and the Rearguard (Jinx, Rebel); on T4 the legend draws, since they hold one card, 2, then 3 after the draw, 1 after Jinx, Rebel and the Saboteur (Dangerous Duo).

Your T2: the Mighty count starts at A. The Ramhound takes A, which is empty: a non-combat showdown, 316.8.b.1: "Showdowns that occur as a result of a player moving to an empty Battlefield are a stand-alone Phase and do not create a Combat." With no rune ready they pass, and 348.2.a.1 makes it a point: "This results in a Conquer if that player has not yet scored that Battlefield this turn." Galio goes to A, which you now control, 355.2.a: "By default, Valid locations include the controller’s Base or a Battlefield the controller controls." That opens no showdown, 190.3.a.1: "Units moving to or being played to a battlefield apply Contested status if that battlefield is not already Contested and that Unit’s controller does not already control that battlefield."

Their T2: they take B, and stack it. The Saboteur walks into B. They have Focus, 345: "As a Showdown begins, the player who applied Contested status to the Battlefield gains Focus." You have one rune ready and nothing in hand to play with it; B is theirs. Jinx comes from the Champion Zone to B and they discard the two cards they drew. Attacking A instead would be pointless: their 3 would go into Galio first, a [Tank] with 6 Might, and the Ramhound's 3 would kill the Saboteur.

Your T3: the Ramhound walks home. You Hold A, 469.2: "Hold: A player maintains Control of a Battlefield they did not yet Score this turn during their Beginning Phase." The Ramhound leaves A for base, 144.4.b: "Units may move from a Battlefield to their Base." A keeps Galio, so you keep A. The Ramhound walks because a unit at A cannot move to B: without [Ganking] the moves are 144.4.b and 144.4.a, "Units may move from their Base to a Battlefield." Jayce goes to base. Two Mighty bodies now: Galio at A, 6, and Jayce in base, 5.

Their T3: B is 14. They Hold B. Their units cannot reach A, which they could only attack from their base, and their base is empty. So they add the Duo and the Rearguard to B: Saboteur 3, Jinx 4, Pouty Poro 2, Duo 3, Rearguard 2. One rune stays ready.

Your T4. All your objects ready, 315.1.b: "1. The Turn Player readies all Game Objects they control that are able to be readied." Jayce becomes ready, his trigger goes on the chain, and you choose [Assault 2]. They get priority with one ready rune and pass. You Hold A: 3. You channel to 6 runes.

The Jaull-Fish is the first thing in your Main Phase: two Mighty bodies, E4 + 3 Body Power with [Accelerate]. Four runes exhausted, three Body recycled, two still ready. It enters ready, 143.4.a: "This can be altered by Accelerate or similar game effects." The Jaull-Fish, Jayce and the Ramhound walk from base into B as one move, 144.3: "Players may perform multiple Units' standard move simultaneously. This is treated as one game action performed on multiple Units." That is a combat, and you have Focus first, 464.2.c.1.a: "If a showdown opens as part of combat, this player gains Focus as the showdown begins." You pass; they have one rune and no card to use it on.

Damage, 465.2.c: "Starting with the Attacker, each player assigns an amount of damage equal to their summed Might among the other's Units." Yours is Jayce 7 while attacking, the Jaull-Fish 6 and the Ramhound 3 with company: 16. Theirs is 14. 465.2.c.3: "Units must have lethal damage assigned to them in full before damage is assigned to a different Unit." Your 16 kill all five of theirs, 3 + 4 + 2 + 3 + 2, with 2 over. Their 14 kill Jayce and the Jaull-Fish, 7 + 6, and put 1 on the Ramhound. Only the Ramhound remains, 466.5.d: "Establishing Control results in a Conquer if that player has not yet scored this Battlefield this turn." That is 4. The last two runes play Daring Poro to B, which you now control, so the Ramhound has company again. Damage heals at the end of the turn, 317.2.b: "Insert “3c. Heal all Units.”"

Their T4. Their board is empty. They hold one card, so Loose Cannon draws, and they play Jinx, Rebel and a second Saboteur to base. Units enter exhausted, 143.4: "Units enter the Board exhausted." B is not reachable this turn. 4 to 2. You end T4 with three runes on the board; they end with seven.

Without the Jaull-Fish on T4: Garen instead. Same draws, same six runes. Garen comes from the Champion Zone to base for six runes, one Body recycled. Jayce 7 and the Ramhound 3 are 10 against B's 14, so nothing attacks. They Hold B: 3 to 3 after their T4, with five runes on your board and the Jaull-Fish still in hand. On T5 there are three Mighty bodies and seven runes, and the Jaull-Fish with [Accelerate] is E2 + 3 Body Power. That is a turn later, against a B that has had another turn.

Insisting on full price. Without the discount the Jaull-Fish is E7 + 2 Body Power, seven runes, or E8 + 3 Body Power ready. On T4 you have six. It cannot be played on T4 at all.

Without [Accelerate]. With two Mighty bodies the Jaull-Fish is E3 + 2 Body Power, three runes, and it enters exhausted. Jayce 7 and the Ramhound 3 attack alone, 10 against 14, and that is no attack. [Accelerate] costs one more Energy, which the discount absorbs only at the floor, with four Mighty bodies, and one more Body rune, which it never does.

The other ordering: Daring Poro first. Played before the Jaull-Fish, the Poro opens a chain, and on it any Reaction they can afford is live (309.1.a, 813.1.c.1). With one ready rune that is nothing that removes a 5, but with three it is UNL-128 Star-Crossed, §5. Played second, it opens nothing that matters: the count is already paid.

How often this happens. The draw pile is 39 cards, the 40 of Tournament Rules 402.1 less the Chosen Champion, which 103.2.a.1 places in the Champion Zone. Tournament Rules 402.1: "In a constructed event, players must register a Main Deck of exactly 40 cards (including a chosen champion), 1 Legend, 12 runes, and exactly 3 battlefields each with a unique name." Going first, you have seen 6 cards by T2, 7 by T3 and 8 by T4. With three copies of each (103.2.b: "Your Main Deck can include up to 3 copies of the same named card."), a Galio among the first 6 is 40.30%, a Jayce among the first 7 45.73%, a Jaull-Fish among the first 8 50.82%, and all three 7.35%.

5. Breaks to

What the engine did, and the predicate. On your T4 two Mighty bodies made a ready Jaull-Fish six runes' worth of affordable, and it was the second body in the attack that took B. The predicate is: played on their T3, or on your T4 before combat damage, does it leave your T4 attack short of B's 14, or the Jaull-Fish unplayable on T4?

The scope. A Fury/Chaos deck plays only Fury, Chaos and Fury/Chaos cards (103.1.b.1), and its Signature cards must carry its legend's tag, 103.2.d.2: "All of the Signature cards must have the Champion tag that corresponds to the Champion Legend of the deck." Loose Cannon's tag is Jinx. The predicate is: a card in those domains in data/cards.json (not a legend, battlefield, rune or token), not a Signature card with another champion's tag. Folded by name, that is 252 cards. Of the five Signature cards in those domains, four carry another tag and are out (OGS-018 Tibbers, SFD-186 Spinning Axe, UNL-186 Death from Below, VEN-144 Death Mark); Jinx's own OGN-252 Super Mega Death Rocket! is in. Five of the 252 are banned in constructed (OGN-168 Fight or Flight, OGN-177 Stealthy Pursuer, OGN-182 Scrapheap, SFD-020 Draven, Vanquisher, SFD-122 Called Shot), which leaves 247.

Taking a Mighty body does not stop the Jaull-Fish; it prices it. With one Mighty body left it is E6

an answer can take is the attack. So the body that matters is the one that attacks.

Window 1: their T3, against your two Mighty bodies. Their own Main Phase, six runes. Swept over the 247 for kill, deal, return, banish, control or a Might penalty together with unit: 63 cards, each read; a second sweep of the other 184 for hand, temporary, recall, recycle or a Might clause added OGN-008 Get Excited! and nothing else that removes a unit. A Might penalty "this turn" played on their turn expires before yours. What is left splits by where it reaches.

VEN-008 Ruthless Strike and OGN-014 Sky Splitter deal 5 only at a battlefield, where the Mighty body is Galio's 6. OGN-029 Falling Star deals 3 and 3; whether both may choose Jayce is not ruled here, and it is not counted.

Window 2: Jayce's trigger on your T4. Before your Beginning Phase his trigger is on the chain and they may answer with a Reaction (309.1.a). 23 of the 247 carry [Reaction] in their text. With one ready rune none of them removes a 5. With three, Star-Crossed returns Jayce there, before the count: the Jaull-Fish is E6 + 3 Body Power and the attack is 9 against B. Keeping three runes up through their T3 leaves them three to spend, so B gets the Duo and not the Rearguard, 12, and Star-Crossed takes one of their own back to hand as well, 10 at most. Nine still do not take it.

Window 3: the combat on your T4. One rune is enough here too. After you pass Focus they play [Action] and [Reaction] cards with the runes they kept, 806.1.b: "Action grants the corresponding card or effect permission to be played or activated during Showdowns, even when it is not the Controlling player's turn." 51 of the 247 carry [Action] or [Reaction]. The attack wins by 2. Anything that takes the Ramhound out of the combat takes 3 off your side: 13 against 14, your 13 cannot kill all five of theirs, and their 14 kill Jayce and the Jaull-Fish. B stays theirs, and you have spent three Body runes for nothing.

Gust, Hextech Ray, Monster Harpoon and Existential Dread tie at one rune: Gust needs no Power, and the other three are the same rune exhausted and then recycled.

The Rocket in your base on their T3 is the clean answer, and Decree of Discord on their T3 or a one-rune card in the combat is the cheap one. None of them answers the discount. The Jaull-Fish is played in every line here; what they deny is the turn it was bought for.

6. Verdict

Right about [Shield], [Assault] and the floor; wrong about what Garen is, and silent on [Accelerate] and on the runes. The count is read on the chain (354, 356) from current Might on the board (708, 710), so a body that is a 5 only in combat counts its printed number, and 356.6 floors the Energy and leaves the Power. But the discount is applied after [Accelerate] is added (356.2, 356.4, 356.4.f), so four Mighty bodies make the ready Jaull-Fish E0 + 3 Body Power, and nineteen mono-Body units that print 5 or more cost less than Garen's E6 + 1 Body Power. Walked going first against a Jinx deck that stacked its battlefield to 14, Galio and Jayce made two, the Jaull-Fish came down ready on T4 for four runes, and with Jayce and the Ramhound it took B: 4 to 2 after their T4. Spending the same turn on Garen is 3 to 3; at full price the Jaull-Fish is not a T4 card at all. The price the discount cannot touch is three recycled Body runes: the line ends T4 with three runes on the board against the control's five, and 30.30% of rune orders cannot pay it on T4. The attack wins by two, so the cheapest cards that break the turn cost one rune: Decree of Discord on the Ramhound in your base on their T3, or in the combat Gust or Hextech Ray on the Ramhound, Monster Harpoon's 2 on it, or Existential Dread on Jayce.

7. Not verified

I did not deal the channel order. The walk assumes six Body and six Order runes for you, Might of Demacia's two domains, in the twelve of Tournament Rules 402.1. Galio on T2 needs an Order among your first four: it fails in 28 of 924, 3.03%. Jayce on T3 and the ready Jaull-Fish on T4 need four Body among your first eight, since four Body leave the board: with Galio's Order as well, the line fails in 280 of 924, 30.30%. The Jaull-Fish without [Accelerate] needs three Body among eight, and with Galio's Order fails in 56 of 924, 6.06%, but then it does not attack. The Garen control needs a Body among six for Jayce and a second among eight for Garen: with Galio's Order, 29 of 924, 3.14%.

Their walk assumes six Fury and six Chaos. Jinx on T2 needs a Fury among their first five: it fails in 7 of 924, 0.76%. Star-Crossed or Decree of Discord on their T3 needs a Chaos among seven, and so does Existential Dread on your T4: 0 of 924. Rebuke on Galio needs two, with its [Deflect] Power of any domain: 7 of 924, 0.76%. Hextech Ray or Monster Harpoon on your T4 needs a second Fury among seven, the first having gone to Jinx: 7 of 924, 0.76%. The Rocket's Power is Fury or Chaos, and Gust takes any rune.

How likely an answer is. Out of their own 39, by your T4 they have seen 7 cards: four opening and a draw on each of their three turns; the legend does not draw before their T4. A Gust, run three times, is among them in 45.73%; a Rocket, a Star-Crossed or a Decree of Discord, the three base-reaching answers that break the attack (nine cards), 86.76%. Those are before the deal. The walk fixes their opening four as non-answers, which leaves three draws from the other 35: three Gusts among them is 24.22%, the nine 60.28%. These count only the cards named, not how many of them a deck runs.

Whether the Jaull-Fish counts itself is not ruled here. On the chain it is in a non-board zone, 328: "The Chain is a Non-Board Zone that temporarily exists whenever a card is played or an ability is activated." And there it is Mighty by its printed 6, 711: "Units in Non-Board Zones are evaluated according to their printed Might." Its text counts "each of your [Mighty] units". 355.9.a.1 says "“Unit,” “gear,” and “rune” refer to objects on the Board unless specified otherwise.", but it is a paragraph about targets, and the count targets nothing. The walk reads the board only, which is the dearer reading. Counted, the ready Jaull-Fish would be E2 + 3 Body Power on T4, and the walk's turn is unchanged but for two more runes ready.

Their hand holding no answer is the walk's assumption; §5 prices it. Not walked: going second, the mulligan, 2v2, a rune split other than six and six, their other assignment in the T4 combat (5 on Jayce, which he survives as an attacker and not after: 143.2.a, "If a Unit ever has nonzero damage marked on it equalling or exceeding its Might, it is Killed."), UNL-013 Lotus Trap hidden at B in that combat, UNL-139 Bone Skewer (it makes you play a unit from your hand to a battlefield, ignoring its costs), OGN-150 Kraken Hunter in place of Jayce, and the board after their T4.
