Hex: Crowd Control

Cleanse 3 (Any play may sacrifice a permanent with
mana value 3 or more. Sacrifice this card at the beginning of the next end step. Cleanse only as a
sorcery.)
Creatures your opponents control enter the battlefield tapped.

Creatures can't attack you unless their controller
pays {x} for each creature they control that is
attacking you, where X is the number of Hex's you control.
