Kithkis and the Damned

Flash
Affinity for Death (Whenever a creature dies, this
spell costs {1} less until end of turn.)
Whenever Kithkis enters the battlefield, exile
each creature in each graveyard that died this
turn. Create a token that is a copy of each of
those creatures. Those creatures are Horrors in addition to their other types.
Horrors you control cannot block.
