Betrayers of Kamigawa
Creature — Ogre Warrior (3/1)
Betrayers of Kamigawa — Uncommon
Whenever Ogre Marauder attacks, it gains "Ogre Marauder is unblockable" until end of turn unless defending player sacrifices a creature.
Once freed, the oni demanded more and more sacrifices to appease them. The ogres happily obliged.
