Temporal Hydra

Whenever you draw a card put a Rift
Counter on Temporal Hydra. If you draw
an enchantment, Temporal Hydra becomes
a 0/0 Hydra Enchantment Creature with X +1/+1 counters on it where X is equal to the number of Rift Counter on it. When Temporal Hydra becomes an Enchantment Creature you may no longer place Rift Counters on it
