Creature â Dinosaur
Players can't gain life.
Whenever another creature enters the battlefield, Rampaging Ferocidon deals 1 damage to that creature's controller.
Spells and abilities that cause players to gain life still resolve while Rampaging Ferocidon is on the battlefield. No player will gain life, but any other effects of that spell or ability will happen.
Rampaging Ferocidonâ€™s last ability triggers whenever any player has a creature enter the battlefield, including you.
If another creature enters the battlefield at the same time as Rampaging Ferocidon, its last ability triggers.
If an effect says to set a playerâ€™s life total to a number thatâ€™s higher than the playerâ€™s current life total while Rampaging Ferocidon is on the battlefield, the playerâ€™s life total doesnâ€™t change.
