Runemarked Hydra

Haste
When Runemarked Hydra enters the battlefield,
you draw X cards, then discard one or more
cards. Put a +1/+1 counter on Runemarked
Hydra for each card discarded in this way.
When Runemarked Hydra dies, return a card
with converted mana cost less than its power
from your graveyard to your hand.
