Hexproof, indestructible
All creature, artifact, and enchant cards you control enter the battlefield facedown
Face down cards have Hexproof and are counted as face down emblems
Face down cards may attack while face down but must turn face up during the damage step or when they want to activate an ability
when this card deals combat damage to a player their life total becomes 1 + {x} where {x} is the amount of face down cards you control
