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 Takklemaggot does one damage to the controller of the last creature Takklemaggot was on, during his or her upkeep. Takklemaggot does not revert to an Enchant Creature even if other creatures are afterwards brought into play.
