Mold-1

At the beginning of your upkeep, you may exile
a creature from your graveyard. If you do, create
a 1/1 green Fungus creature token.
Whenever a Fungus you control dies, if it was destroyed by a creature, you may have the
creature that destroyed it fight another target
creature you don't control.
"Please refrain from eating the spores."
