Put a 0/-1 counter on target creature during its controller’s upkeep. If the creature is placed in the graveyard, its controller chooses a new target for Takklemaggot. If there are no legal targets, Takklemaggot becomes an Enchantment and does 1 damage to the controller of the last creature Takklemaggot was on, during his or her upkeep. Takklemaggot does not revert to a creature enchantment even if other creatures are afterwards brought into play.
