Indominus Rex, Alpha Foil

Legendary Creature — Dinosaur Mutant

As Indominus Rex enters, discard any number of creature cards. It enters with a flying counter on it if a card discarded this way has flying. The same is true for first strike, double strike, deathtouch, hexproof, haste, indestructible, lifelink, menace, reach, trample, and vigilance. When Indominus Rex enters, draw a card for each counter on it.
