Bridge from Below

A card that does nothing from anywhere you can cast it. The trick its designers buried in the wording is that both triggers fire only while it sits in the graveyard, which makes the cost line almost a misdirection: you never want to pay it, you want to discard or mill it and let it work from the bin. From there it converts your own dying nontoken creatures into 2/2 Zombies, one Bridge in the yard per creature, several Bridges per creature death once you stack copies. That self-replicating loop is what made it a centerpiece of graveyard-recursion strategies that chained sacrifice outlets and cheap reanimation into armies that appeared faster than removal could keep pace. The second clause is the leash the rest of the design hangs on: when one of your opponent's creatures dies, every Bridge in your graveyard exiles itself, so the engine assumes a board state where their creatures are not dying at all. That asymmetry is precisely what made it dangerous in the formats where it earned bans: a combo deck never lets the opponent's creatures hit the yard, so the exile clause that was supposed to keep it honest simply never triggers. The card is a clean study in placing a powerful effect in the one zone players spend most games trying to fill, then pricing the safety valve to a battlefield interaction the abuser controls.
