Uravesk Who Walks Behind Veils

Start the game with 20 lifepoints and four obelisk
cards from your boss-sideboard at the battlefield.
Players can attack you once there are no obelisks
left on the battlefield.
Each obelisk has its own combat zone.
Whenever you cast a creature spell, determine
the battle zone in which the creature should
appear. Creatures cannot block for obelisks
in other battle zones.
