Agyrem

Whenever a white creature dies, return it to the battlefield under its owner's control
at the beginning of the next end step,
it has cumulative upkeep - drink shots equal to its
mana cost. If its nonwhite, you may return it to its
owner's hand at the beginning of the next end step,
drink shots equal to its cmc.
Whenever you roll CHAOS, creatures can't attack
you until a player planeswalks or drinks 2 shots
for each attacking creature.
