Behemoth

Trample
Behemoth enters the battlefield with three Chain counters on it.
As long as Behemoth has a Chain counter, it has hexproof.
At the beginning of your upkeep, remove a Chain counter from Behemoth. Then, if it has no Chain counters on it, it becomes Enraged, loses Hexproof, and gains Double Strike and Haste.
When Behemoth becomes Enraged, it deals 3 damage to each other creature.
