Canyon Meduo

Unseen (When this creature is drawn, unreaveled, reveal it and return it to your library face up. You may then pay it's mana cost at any time to summon it to your battlefield. If you draw this creature when revealed, deal 3 damage to target player.)
When Canyon Meduo deals damage to an enemy creature, tap it until next turn's upkeep step.
Meduo are rare, and unseen. Their predation as vicious as wolves and their hearts cold as stone.
