Corruption Artisan

When Corruption Artisan enters the battlefield,
you get a poison counter and an endurance
counter. (Players with endurance counters cannot
lose the game for having 10 or more poison counter
unless the number of poison counters that player has
minus the number of endurance counters that player
has equals 10 or more.)
Whenever Venomous Artisan deals combat
damage to a player, proliferate.
