{t}{1}{g}{u}: choose a creature in any graveyard.
Summon it to your side of the battlefield, but
with a 0/4 Spore Counter on it and it is called
Spore Servant.
A opponent may choose to attack the spore
counter on the creature, and if it is

the creature goes back to it's original graveyard,
while the same happens if the creature is
destroyed.
