Tusk ACT 3

Whenever a creature enters the battlefield, if it
was cast, you may put a nail counter on it.
At the beginning of your upkeep, choose one —
• Tusk ACT 4 deals 3 damage to target creature
with a nail counter on it
• Exile each creature with a nail counter on it.
Return those cards to the battlefield at the
beginning of the next end step.
