Step Through
The seam is what makes this work: a five-mana double-bounce welded to a tutor that fetches any Wizard, and the two halves almost never want to be the same card in the same game. Nobody builds a deck to hard-cast this; the bounce is the floor, the search is the reason it earns a maindeck slot. Typecycling is the mechanism that lets one card play either role depending on the board. Ordinary cycling turns a stalled card into a fresh draw at random; the type-restricted variants sharpen that by guaranteeing the hit, and Step Through attaches a genuine spell to the far end of that transaction rather than a raw card. So the card is dead-hand insurance that also happens to be a real tempo play: return two creatures when you would rather cast than dig, or discard it to find the exact Wizard the matchup demands. It rewards a tribal shell dense enough that the search rarely comes up empty, and it asks nothing extra of a deck that would already run a bounce spell for tempo. Built for the wizard who has options and wants a way to hedge both.
