Tribute

Tribute is a ability word introduced in Born of the Gods. It gives opponents an unfortunate choice: have the creature grow in size, or allow a powerful enters-the-battlefield ability to trigger.

E.g. Tribute 3 (As this creature enters the battlefield, an opponent of your choice may put 3 +1/+1 counters on it.) When [cardname] enters the battlefield, if its tribute wasn't paid, destroy target noncreature permanent.
