Blightmist

Choose one —
• Put two -1/-1 counters on target creature.
• Until end of turn, target creature gains "When
this creature dies, return it to the battlefield
tapped under its owner's control."
Blightmists, or pockets of lingering magical fallout, are
best avoided. Those who come in contact with it will
surely mutate, and the effects of those mutations are
quite unpredictable.
