Stonefare Crocodile

Oracle Text

2B: Stonefare Crocodile gains lifelink until end of turn. (Damage dealt by this creature also causes you to gain that much life.)

Card Rulings

10/1/2012 multiple instances of lifelink on the same creature are redundant. Activating Stonefare Crocodile’s ability more than once during a single turn won’t cause you to gain more life.
