Korvold's Foot Fungus

If a player sacrificing a permanent or a creature
dying due to it being sacrificed causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.
Whenever you activate an ability of a permanent
you control, if you sacrificed a permanent to
activate it, copy that ability. You may choose new targets for the copy.
Sacrifice a permanent: Add one mana of any color.
Whenever a player sacrifices a permanent, draw
a card.
