Sona holds the wall up, and the board stops growing

Issue #309 (a slice of #200), 2026-10-07. 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. Read the unopposed clock for the baseline this is measured against.

Subject: sona-wind-wall-condition-not-effect, the Calm ENGINE in which OGN-073 Sona, Harmonious readies up to four runes at the end of your turn and OGN-064 Wind Wall spends them on the opponent's turn to counter a spell. The entry is right about the rule, and the case is Riot's own: the first example at 383.2.a.1 is this card. Walked as a game, the line works. Sona lands on T3, and her own runes counter the two removal spells aimed at her on the opponent's T3 and T4. The price is not in Energy. Every Wind Wall recycles two runes, which is exactly what the Channel Phase brings back, so on the turns you hold the wall up your board does not grow: five runes on T4 and on T5, where it would have been eight and ten. When the opponent plays only units, the readied runes have nothing to counter. What breaks the line is VEN-015 Decree of Rage: one rune, cast on their own turn. It can't be countered, and it names Sona's domain.

Why this line. scripts/sequence-pick.mjs --unplayed, re-run on 2026-10-07 at 4015c20, reads 771 entries, 262 with forced-ordering language, 102 in the queue and 63 of them with no play, unchanged from the issue. The pick is by global rank, skipping entries that already have a play: this entry is rank 36 (a hit on in response), first in the list. The other entry of this slice is rank 37, played in the refill held for the Burn Out never gets a turn.

1. Needs

The card text the play turns on:

2. The trigger is decided when it is placed

383.2.a.1: "Any additional conditional statement immediately after the Condition must be true in order for the Condition to be fulfilled. Such a conditional statement is part of the Trigger Condition and not the Effect." Riot's example is this card: "Her Trigger Ability’s Condition will be fulfilled in the Ending Step, but the Triggered Ability will only be placed on the chain if she is located at a battlefield when the Condition is fulfilled. If she is removed in reaction to the triggered ability, it will still resolve." So the readied runes are safe once the trigger is on the chain.

The other half of the same paragraph is the card across the table in this walk. Loose Cannon is the opponent's legend, and Riot's second example says its "if you have one or fewer cards in your hand" clause "is not immediately after the trigger condition, so it is part of the effect and not the condition." Their hand never drops to one in this game, so the legend never draws.

What the trigger buys is the opponent's turn. 415.3.a: "A player Readies all non-spell Game Objects they Control during the Awakening Phase on their turn." A rune you tap on your turn would normally stay exhausted through theirs. Sona readies it in the Ending Step, after 167 has emptied the pool ("Every player's Rune Pool empties at the start of each player's Main Phase and the end of each player's turn."), and the rune itself is what carries over. Wind Wall then costs three of those runes tapped and two Calm runes recycled.

The recycle is the price, and it is paid in board. 164.2.b reads "Recycle this: [Reaction] — Add [C]." That needs no exhaust, so the entry is right that a tapped rune still pays Power. But 161.2.b: "When a Rune is Recycled it is returned to the Rune Deck, not the Main Deck." And 416.1 puts it "on the bottom of the corresponding deck." The Channel Phase, 315.3.b, says "The Turn Player channels 2 runes from their Rune Deck." Until the twelfth rune is out, those two come off the top whatever you recycled, so a recycled rune is a rune of growth lost. One Wind Wall a round is two recycles, and the round ends with the board where it started.

3. Their order: removal at Sona, then units

Fury/Chaos with OGN-251 Loose Cannon, holding B. Going second, the 485.7 extra rune gives them seven runes on their T3. Their plan for Sona is the ordinary one: an [Action] removal spell on their own turn, when she is a 4-Might unit at a battlefield. Void Seeker deals four, which kills her. On their T4 Sky Splitter costs five Energy and one Fury Power, cut from eight by their 3-Might Skulker, and deals five.

4. The turns, going first

Calm/Mind against Fury/Chaos. Your rune deck is nine Calm and three Mind.

turn    runes   your turn                                                 points
T1      2       Stalwart Poro (E2) to base                                0
their T1        Mystic Poro to base, with the 485.7 extra rune.
T2      4       Poro walks to A, Conquer: +1. Mutated Mouser (E2) to A.   1
their T2        Mystic Poro walks to B, Conquer. Shipyard Skulker (E3)
                to B.
T3      6       Hold A: +1. Sona (E4 + 1 Calm) to A: four tapped, one of  2
                them recycled, five runes left. Ending Step: she is at
                A, so the trigger goes on the chain and readies the
                three still exhausted. Five ready.
their T3        Hold B. Void Seeker on Sona. Wind Wall: three tapped,
                two Calm recycled, three runes left. Countered: no
                damage and no draw. Flame Chompers (E3) to B.
T4      5       Hold A: +1. Sunlit Guardian (E3) to A, two idle. Ending   3
                Step: three readied, five ready.
their T4        Hold B. Sky Splitter on Sona (E5 + 1 Fury). Wind Wall
                again: three runes left. Pouty Poro (E2) to B.
T5      5       Hold A: +1. Allay, Eager Admirer (E3) to A, two idle.     4
                Five ready at the Ending Step.
their T5        Hold B. Jinx, Rebel (E5 + 1 Chaos) and Kai'Sa, Survivor
                (E4) to B. No spell is cast, so the five ready runes
                have nothing to counter.
T6      7       Hold A: +1. A second Sunlit Guardian (E3) and a second    5
                Stalwart Poro (E2) to A, two idle.
their T6        Hold B.

Their points: 1 on T2, then one Hold a turn, 5 on T6. The opponent was never idle. They took B, spent two removal spells on Sona, and built B to nineteen Might.

Your runes: twelve channeled by T6 and five recycled, one for Sona and four for the two Wind Walls. That leaves five on T4, five on T5 and seven on T6. Without Sona and the Walls the same turns have eight, ten and twelve. In this game the freeze cost nothing, because the hand was three-drops and two runes idled on each of those turns anyway. A hand holding a six-drop on T4 would have felt it.

Their T5 is the other cost. 337.2: "If, after finalizing the Chain Item, that item is a Unit, Gear, or an ability that Adds resources, it resolves immediately". A unit gives no window, and a [Reaction] in the pool that counters one does not exist. So the five runes Sona readied on T5 did nothing. The opponent decides which turns the engine is worth anything.

From T6 on, the race is the one the unopposed clock prices. A defends at twenty-four Might (Stalwart Poro 3 and Mutated Mouser 3 with their [Shield], Sona 4, two Sunlit Guardians 4 each, Allay 3, the second Poro 3), B at nineteen plus their T6. You hold A to eight on T9, a turn before they reach eight on theirs, unless they take A first.

5. Breaks to

The line breaks to VEN-015 Decree of Rage (Fury, E1 + 1 Power: one rune, tapped for the Energy and then recycled for the Power), cast on their T3 in place of Void Seeker: "[Action] (Play on your turn or in showdowns.) This can't be countered. Deal 4 to an enemy Calm (:rb_rune_calm:) unit." Sona has four Might and is Calm, so she dies. Wind Wall cannot touch it. 425.1.a says "A card or ability that is Countered does nothing and is cleared from the chain.", and this card says it can't be countered. The runes she readied on T3 are still ready, because that trigger resolved before their turn began, so you keep five runes for one Wind Wall on something else. There is no second trigger. You paid four runes and a card for one turn of the engine; they paid one rune, and Decree of Rage is not a Signature card, so any Fury deck can run it.

The entry says the only window that beats Sona is before the Ending Step, on your turn. That is true of the trigger, and 383.2.a.1 says so. It is not true of the engine. Decree of Rage is cast on their own turn, after the trigger has resolved, and it ends every later cycle.

The reply is a buff. In Calm/Body, OGN-257 Blind Monk reads ":rb_energy_1:, :rb_exhaust:: Buff a friendly unit. (If it doesn't have a buff, it gets a +1 :rb_might: buff.)". That puts Sona at five, so Decree of Rage and Void Seeker no longer kill her. In this Calm/Mind list the best reply is Allay at A: "While I'm at a battlefield, your other units here have [Deflect]." That makes Decree of Rage E1 + 2 Power, two runes, but does not stop it.

6. Verdict

Right, and it pays for its own protection, but it holds the board still and it dies for one rune. The rules reading is right: the readied runes survive removal in response, and Sona's own runes countered both spells aimed at her. The play adds two prices. The Power for each Wind Wall is two runes the board does not get back until the twelfth rune is out, so a wall held up every round keeps you at five runes. And the four readied Energy count only on turns the opponent casts a spell. The cheapest answer in the pool needs no counter-play at all, because it can't be countered.

7. Not verified

The walk assumes two Calm runes are on the board at each Wind Wall. With nine Calm of twelve that held here, but I did not deal the channel order. I did not walk their T7 to T9, so I don't know whether nineteen Might plus three more turns of units takes A. I did not walk OGN-033 Shakedown, a [Reaction] that could hit Sona on your turn, which needs a Closed State there to be played into. I did not walk 2v2 or the VEN-SP2 reprint.
