Prideful Feastling

Two flexibilities stack in the same slot, and they compound rather than merely coexist. The white-or-black casting pip lets the card slot into either color without disturbing a manabase, and changeling means it counts as every creature type there is. Put those together and you get a lifelinker that registers as a Goblin to your Goblin lords, an Elf to your Elf payoffs, and a Vampire to your Vampire aristocrats, all from a single card that most tribal fillers cannot match because they commit to one type and one color. Changeling has always been the mechanic that lets a body belong to a deck it was never literally printed for; wrapping it around the flexible cost extends that reach across two colors' worth of type-matters shells. The 2/3 body is honest about the trade: this is a curve-filler that keeps its lord bonuses live and drips life while it blocks or trades, not a threat you build around. That modesty is the balancing math. Universal creature typing is worth a great deal in the right shell, so the payoff comes in what the card counts as rather than what it does in combat, a defensive footprint with incidental lifegain instead of an evasive clock. Unremarkable in isolation, it earns its keep the moment a tribe wants a warm body of the correct type in the correct color, and the changeling clause guarantees the type is always correct.
