A color-changing trick built as a cantrip, and a strange one: the effect it grants is almost entirely defensive misdirection. Changing a land's basic type for a turn does little on its own, so the card lives or dies on what your other cards do with that altered type. Point it at an opponent's land to neutralize a type-matters payoff, or rewrite your own land's type to slot into a color requirement you could not otherwise meet. The delayed draw is the load-bearing piece: it never feels like a wasted card because the cantrip backstops the gimmick, letting the instant-speed flexibility justify itself even when the type change does nothing. That delayed-upkeep trigger, rather than an immediate draw on resolution, is the telling design choice; it pushes the card-advantage payoff a full turn into the future, so you spend two mana now and recoup the card only after passing priority. It is a small, fussy puzzle piece from an era when blue's instants were full of narrow utility riders, the kind of card whose ceiling depends entirely on a deck built to exploit land types rather than on the spell itself.
