Other Dinosaurs you control have haste.
When this creature enters, create a 3/3 green Dinosaur creature token with trample.

Creature spells you cast cost {1} less to cast.
Whenever another creature you control enters, this creature deals 2 damage to it. If a Dinosaur is dealt damage this way, this creature gets +2/+0 until end of turn.

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

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

Vigilance, trample, haste
Whenever Gishath deals combat damage to a player, reveal that many cards from the top of your library. Put any number of Dinosaur creature cards from among them onto the battlefield and the rest on the bottom of your library in a random order.
