The payload here is taxonomy, not stats. The +0/+1 is almost decorative: a single point of toughness, just enough to slip a creature out of a one-damage ping or win a trade you would otherwise lose. The real work is the type-flooding clause, which hands a chosen player's creatures every creature type at once. That is a profoundly odd thing to want in a vacuum, and it only makes sense in a design language built around tribal payoffs: anthems that pump a chosen type, lords that buff their kin, spells that count or care about creatures sharing a type. For one white mana at instant speed, this turns a board into Goblins and Elves and Soldiers and Faeries simultaneously, firing every tribal bonus in play. Crucially, the clause names "target player," so the choice need not be you: pointing it at an opponent can switch on a punisher effect that cares about shared types, or hand a foe a creature type that some other card of yours hates out. The changeling line on the spell itself is the same idea folded back, since it counts as every creature type even in the graveyard or as a target. The effect is binary, either a deck is stuffed with type-conditional triggers or the line does nothing, but as rules architecture it cleanly demonstrates how changeling decouples creature identity from creature body. The toughness is the floor; the type-grant is the ceiling, and the ceiling needs a deck willing to reach for it.
