Dimitris, the Judge

Skulk, toxic 1
Whenever you cast a Zombie spell, target
instant or sorcery card in your graveyard gains
flashback until end of turn. The flashback cost
is equal to its mana cost.
Whenever an opponent searches their library,
that player gets two poison counters.
Whenever another nontoken creature you
control dies, you may exile it. If you do, create
a token that's a copy of that creature, except it's
a 2/2 black Zombie and has toxic 1.
