Payoff

Deck

• Legend domains cover Mind (LeBlanc and Keeper are both Mind).

Prerequisites

• You control The Grand Plaza (random 1 of 3 in Duel, chosen in Match) with LeBlanc on it.
• 355.2.a makes a battlefield you control a default play location for units, so all three Keepers go straight to the Plaza and their Reflections appear 'here'. [Ambush] (822.1.b) is only needed for battlefields you do NOT control.
• 811.1.b caps hidden cards at one per battlefield, so exactly one Keeper is free; the other two cost 2 Energy each.
• Might is not a copyable trait (477.1.b.1.a), so the six Reflections stay at the token's printed 0 Might. They do not die of it (142.4: a 0 Might unit still needs 1 damage marked), but any single point of damage removes one, and killing LeBlanc un-suppresses every [Temporary] at once. Survive one opponent turn, or close the window with Time Warp.
• 323.7 — THE FREE KEEPER IS DESTROYED IF THE PLAZA CHANGES HANDS. The one Keeper of Masks hidden at the Plaza is removed and placed in its owner's trash by a Cleanup (323.7) or the moment another player establishes Control (466.5.c). Losing the Plaza costs the card as well as the position.
• ONE ENERGY ANSWERS THE MIGHT-1 BODY THIS LINE NEEDS (Keeper of Masks (M1)). OGN-133 Flurry of Blades is Body, E1: "[Reaction] (Play any time, even before spells and abilities resolve.) Deal 1 to all units at battlefields." 143.2.a kills on marked damage at or above Might, so it kills every 1-Might body on the board SIMULTANEOUSLY however many there are - the binding constraint is Might PER BODY, not the number of bodies, so no amount of going wider answers it - and 813.1.c.1 lets it land in any Closed State on either player's turn. THE NAMED REPAIR DOES NOTHING ON THIS BOARD, and this is the worst instance of the correction made on `keeper-of-masks-flurry-plaza-window` (corrected 2026-09-13). The garrison is `UNL-090 LeBlanc` at Might 4, THREE `UNL-081 Keeper of Masks` at printed Might 1 — unit CARDS — and SIX Reflection tokens at ZERO Might (187.6, with R27 keeping a copy at 0). `UNL-077 Soul Shepherd` reads *"Your token units have +1 :rb_might:"* — TOKEN units — so it never touches the three Keepers, and it lifts the Reflections from 0 to 1, which 143.2.a still kills on 1 damage: `OGN-133` takes NINE OF THE TEN BODIES with or without it, leaving LeBlanc alone against a bar of seven. The identity is mono-Mind, so the Shepherd is perfectly LEGAL and simply inert — a caveat makes a claim honest, it does not make the card an answer. THE ONE ANSWER THAT CLEARS THE BAR is `UNL-147 Baron Nashor` (mono-Chaos, E10 + 3 Power): *"Other friendly units have +2 :rb_might:"*, board-wide with no location clause, so the Keepers reach 3 and the Reflections 2 and Flurry kills nothing. He costs this deck its second domain — and UNLIKE THE GUTTER PALACE SIBLING his own body is harmless here, because he enters at the Baron Pit (187.9), so he is not one of the Plaza's seven, and the Plaza asks for 7+ rather than EXACTLY, so an extra body cannot overshoot it.
• THE PARAGRAPH THAT AUTHORISES THE NAMED DESTINATION, ADDED BESIDE 355.2.a RATHER THAN INSTEAD OF IT (#204, from #187 batch 18). 355.2.a is the DEFAULT for playing a card - 'By default, Valid locations include the controller's Base or a Battlefield the controller controls' - and it is what this entry already cites. It is not a permission for a token-creating effect to NARROW that, and the paragraph that is has been cited by nothing in 766 entries: 184.2, 'The effect may restrict the location to which the token may be played.' That is what makes a printed 'here' a legal instruction rather than a contradiction of the default. The system is three paragraphs - 184.2 narrows, 355.2.a defaults, 355.2.b widens - and this catalogue was citing two of the three. Both are true here and the pair is the finding.
• THE BATTLEFIELD CAVEAT, WHICH THIS ENTRY WAS THE ONE OF 119 THAT DID NOT STATE IT (2026-09-13). `OGN-293 The Grand Plaza` is in `uses`, and a battlefield is not a card you simply draw. IN A DUEL 485.4.a has each player provide three and 485.5 "randomly selects one (1) of their three (3) Battlefields", so the Plaza arrives roughly ONE GAME IN THREE. IN A MATCH 486.5 drops the word randomly - "Each player selects one (1) of their three (3) Battlefields" - so game 1 is a FREE CHOICE and the line is available whenever it wants, and then the battlefields used are "to be removed and not selected again for this Match" if a player won, so it executes in at most ONE GAME OF THREE and cannot be repeated. 103.4.c forbids the obvious dodge of bringing three copies of one name. THIS MATTERS MOST IN THIS CLASS RATHER THAN LEAST: the sentence the site puts in front of a player here is that you win the game, and the card that wins it is the one card in the list whose presence is not the player's to guarantee. 170.3, 170.4 and 185.2.e are the compensation - once it IS on the board nothing in the game removes it.
• OPPONENT BOARD AND KILL PRICE - ADDED 2026-10-27 (#503). THE BOARD IT WINS ON: nothing of theirs that can bring 4 Might of attackers to the Plaza on their own turn. Seven of the ten must survive their whole turn, because 383.2.a.1 counts them when the Hold happens in your next Beginning Phase (315.2.b.2); a body of theirs ready in their base after their Awaken can Standard Move to the Plaza (144.2, 144.4.a), a body at their own battlefield cannot (144.4.a, 144.4.b) unless it has Ganking (144.4.c.1), and a body they play that turn enters exhausted (143.4) unless it has [Accelerate]. THE KILL PRICE: the line builds ten units, so the attacker has to kill 10 - 6 = 4. LeBlanc has [Backline] (826) so she is assigned damage last (465.2.c.6), and the cheapest four are the 0-Might Reflections (187.6), 1 damage each since lethal is non-zero damage of at least Might (142.4.b): 4 damage, not 13. Killing LeBlanc herself by combat does not shortcut it, because [Backline] forces all nine others first, 9 damage, then her 4; only a non-combat kill of LeBlanc un-suppresses [Temporary] and takes nine units at the start of your Beginning Phase.

Steps

1. Conquer the Plaza; play LeBlanc there.
2. Play Keeper of Masks to the Plaza three times: each brings two Reflection copies. Ten units.
3. Opponent's turn passes.
4. Your Beginning Phase: the Temporary kill does not trigger at LeBlanc's battlefield; you Hold with 7+ units → win (195).
