Daemia, Scribe of the Infernal

Whenever a Demon, Devil, Imp, Vampire, or
Zombie enters the battlefield under your control,
Daemia deals 1 damage to each opponent, then
you may put a doom counter on Daemia.
At the beginning of each opponent's end step,
you may pay {x}, where X is the number of doom counters on Daemia. If you do, that player sacrifices that many creatures and/or
planeswalkers.
