How Mortimer wins

The engine

Every Undead death buffs ALL your Undead — even in shop and hand. Cursed is the accelerant: a Cursed unit dies right after it attacks, so it deliberately triggers the death payoff each combat. Chain deaths to explode the board.

The game plan

Baron Von Buffed chains — each death summons another Baron (with Cursed) that attacks, dies, and buffs every Undead again. The board compounds with every death in combat.

Positioning
  • Cursed units (die after attacking) go in slots 1–2 — they swing, die, and fire the all-Undead death buff BEFORE the rest of your board attacks this turn.
  • Front-load the death chain: Baron Von Buffed wants early, ordered deaths to compound across the board.
  • Keep a persistent buff-holder in the back to bank the stacking Undead buffs.
