Thanos

Ascend (If you control ten or more permanents, you
get the city's blessing for the rest of the game.)
When Thanos enters the battlefield each
opponent sacrifices a creature. Sacrifice Thanos:
if you have the city's blessing (The infinity stones)
and Infinity Gauntlet is attached to Thanos, and
each opponent sacrifices half the creatures he or
she controls at random, rounded up.
"I am inevitable."
