Game becomes unplayable due to an infinite trigger loop. Opponent's board: Invisible Woman, Sue Storm + Ajani's Pridemate + Tigra, Feline Fury + Hinterland Sanctifier + Dazzling Angel + Case of the Uneaten Feast.

Loop: a creature enters → lifegain triggers → +1/+1 counters go on Heroes → Invisible Woman creates a 0/4 Wall token → the Wall entering restarts the chain.

The loop does not terminate. Trigger counter reached 90+ and kept climbing; opponent's life went from 37 to 67 and Wall tokens reached 21+. Game state never repeats (life total and counters increase each iteration), so the loop detector never fires. Sue Storm's ability is "you may", so it also isn't treated as a mandatory loop.

Expected: the client should offer a shortcut/iteration count or declare a draw. Actual: the game becomes effectively softlocked and the only option is to concede.

Format: Standard Bo1, Arena ladder. Reproducible whenever this board state assembles.
