Creature â Manticore
When Manticore of the Gauntlet enters the battlefield, put a -1/-1 counter on target creature you control. Manticore of the Gauntlet deals 3 damage to target opponent or planeswalker.5/4
If you canâ€™t choose a target opponent when you put Manticore of the Gauntletâ€™s triggered ability on the stack (most likely because your opponents have hexproof), the ability is removed from the stack and you wonâ€™t put a -1/-1 counter on any creature.
If either target becomes illegal after Manticore of the Gauntletâ€™s triggered ability is put onto the stack but before it resolves, the other is still affected as appropriate.
