Trample When Ghalta enters, put any number of creature cards from your hand onto the battlefield.

Double strike Whenever this creature attacks, other creatures you control gain double strike until end of turn.

First strike Dinosaur spells you cast have prowl {2}{R}. (You may cast a spell for its prowl cost if you dealt combat damage to a player this turn with a creature with any of its creature types.)

Devour 3 (As this creature enters, you may sacrifice any number of creatures. It enters with three times that many +1/+1 counters on it.)

If a source would deal damage to another Dinosaur you control, prevent all but 1 of that damage.

When this creature enters, if you cast it from your hand, destroy all non-Dinosaur creatures.

Whenever a creature you control attacks, it gets +1/+0 until end of turn for each other attacking creature that shares a creature type with it.
