Sea Snidd
Tap to turn any land into the basic type of your choosing, and the question becomes who actually wants that. The answer in this 3/3 Beast is mostly the manabase: it fixes your own colors by retyping a dual or a fetchable land, and it punctures someone else's plan by feeding their lands a type they never built for. The interesting work is offensive rather than corrective. Strip a creature land of its nonbasic identity, hand an opponent's untapped Island a type that turns on your own land-destruction-by-type, or simply make a land legal for an effect that cares about basic types. The rate is the problem: a five-mana body attached to a repeatable land-typechanger asks a creature and a tap to do something most decks would rather a single spell handle once. It sits in a thread of early color-fixing and domain experiments that kept circling the land grid, an odd descendant of that work: a creature whose entire utility is rewriting types one tap at a time. The point of stapling the toolbox to a body is durability: it survives, recurs, and reuses, which is the whole case for it and also the reason it never found a deck. The ability is too narrow for fixing-only builds and too slow for the type-matters payoffs that would make it sing.
