Scathing Repurcussions

Create a 6/6 black and red demon creature token
with trample and "Whenever a creature blocks
this creature, each player sacrifices a permanent,
mills 1, and returns a card from exile to its
owner's graveyard."
Each player selects a card in their graveyard
at random. If they select a creature card, put it
on the battlefield and you create a copy of the
demon token created with this spell.
