Ghostly Changeling

One body that answers to every lord at once is the whole pitch of the changeling keyword, and the black member of the color-coded growth cycle takes that universal type line and bolts on a way to win without it. Because it reads as Goblin, Elf, Merfolk, and Faerie simultaneously, any pump aimed at a single tribe lands here too, and a focused deck can run it without watering down its type count. The black mana sink is the hedge against the synergy never showing: pay one and black for a +1/+1 that holds until end of turn, repeatable as long as the mana lasts, and the generic 2/2 frame becomes a threat that grows on its own clock. That self-reliance is the balancing logic. The keyword carries the tribal weight, the body is deliberately plain, and the repeatable pump means the card scales in a grind rather than sitting inert when the rest of the synergies fail to arrive. Among the shapeshifters built on changeling plus a colored growth ability, this one earns its slot as an actual threat rather than pure type-line filler, since a long game keeps feeding the same activation.
