Incoherent One

Incoherent One can't be the target of spells or
abilities.
Devastate (If this creature would deal combat
damage to a player, it instead deals 1 damage to that
player for each card in his or her graveyard.)
Whenever Incoherent One deals combat damage
to a player, that player puts that many cards from
on top of their library into their graveyard.
Whenever Incoherent One becomes blocked, you
may return a Possessed creature from your
graveyard to your hand.
