Necroshock

Necroshock deals X damage to any nonplayer
target. If a creature dealt damage this way would
die this turn, put a 2/2 black Zombie creature
token with haste into play under your control.
Madness {x}{b} (If you discard this card,
discard it into exile. When you do, cast it for
its madness cost or put it into your graveyard.)
