If all opponents choose "Confession," they each take 8 damage
But this also works with any of the other treasure makers adding extra value to any of the triggers
Im even going to try this one out: Creatures (23) 4 Rattleclaw Mystic 3 Whisperwood Elemental 3 Den Protector 2 Deathmist Raptor 3 Nissa, Vastwood Seer 4 Hangarback Walker 2 Oblivion Sower 2 Ulamog, the Ceaseless Hunger Planeswalkers (3) Lands (26) Spells (8) From Beyond gets better when the 1/1s actually threaten to trade with stuff and when you go up on fetchable Eldrazi options
But then there are the misfits, the creature types with clear flavor and mechanics, but no general to hold the banner
While alternate win conditions can be fun, I prefer cards like Door to Nothingness over poison-based cards
