Passwall Adept

Granting unblockable has always been a finisher pretending to be something subtler, and the choice to hang it off a repeatable creature activation, rather than a spell that spends itself in one push, changes the strategic axis entirely. Three mana per use is too expensive to ever function as combat tempo; the price points the card at a single decisive turn, channeling all that paid-for evasion into one creature you have spent the game inflating. A 1/3 sits behind the lines, durable enough to shrug off a stray ping or a chump-block trade, hopeless as an attacker on its own. It is built to point elsewhere: to take whatever carries your damage and walk it through an empty red zone the turn you decide the game is over. The repeatability is what separates it from the one-and-done unblockable effects that came before it. A single Aqueous Form commits to one target and one push; a creature with the ability on tap lets you re-aim it every combat step, threatening the kill again and again until the opponent finds an answer for the Adept itself. It wants a board where one creature outweighs the rest, the voltron pattern or the lone connecting menace, and asks only that you keep the mana open to close.
