Why this bracket?

  • 4 repeatable damage-to-each-opponent sources — a dedicated noncombat burn engine — but the goldfish sim wins around turn 8 (Bracket 2 "Core" pace, ~8+ turns), not the ~6-7 of an Upgraded deck, so this theme engine alone does not floor Bracket 3
  • Noncombat burst finish: 3 scaling-burn payoffs (Dragon Tempest, Scourge of Valkas) — but it is finite and comes together slowly (goldfish ~turn 8, Bracket 2 pace), so it does not floor Bracket 3 on its own
  • Borderline verdict — close to B3: noncombat burst finish (Leyline Tyrant + Blasphemous Act) — a real combo kill that's finite/board-dependent, so the two-card-infinite rule doesn't gate it
  • Noncombat burst finish: Leyline Tyrant + Blasphemous Act; scaling burn (Dragon Tempest, Scourge of Valkas) — finite and board-dependent, so it doesn't trip the two-card-infinite floor, but it's a real combo kill this list is built toward
  • High optimization — score 24/75 (17 interaction spells, 12 card-advantage sources, 1 fast-mana sources) — raises this deck above its hard floor
  • Engine accuracy reference: 100% bracket-in-range across 36 validation decks (engine beats Claude Sonnet/Opus/Haiku on bracket-exact).
