Toxic Addiction

At the beginning of each player's upkeep, that
player may get or lose any number of poison
counters.
Creatures get +X/+X, where X is the number of
poison counters their controller has.
Post Mortem: All creatures have infect. (When
this card's owner loses the game, if there are at least
two more players, all players get an emblem with "All creatures have infect.")
