Exile target creature card from a graveyard, then create X 1/1 green Saproling creature tokens, where X is the exiled card's toughness.
If a creature card has “*” in its toughness, the ability that defines “*” works in all zones. The value of X is equal to the toughness of the targeted creature card as it last existed in the graveyard.
If the targeted card is removed from the graveyard before Morbid Bloom resolves, the spell doesn’t resolve. You won’t get any Saproling tokens.
