Derp Thanos

When Derp Thanos enters the battlefield, any
opponent may snap their fingers.
If they don't, Derp Thanos's owner draws cards
equal to the number of creatures on the
battlefield. If they do, for each creature on
the battlefield other than Derp Thanos, flip
a coin. For each coin that comes up heads,
exile the creature for whom the coin was
flipped. Derp Thanos's owner draws a card
for each creature exiled this way.
