Wall of Deceit

Most morph creatures hide an aggressive flip: a creature whose face-up state ambushes combat or blanks a removal spell. This one inverts the whole premise. The morph here is not a way out of being a 2/2; it is a way back into one. The face-up side is an immovable 0/5 wall, but the ability to turn it face down again means the body is never locked into either mode. Threatened by a sweeper that hits small creatures? Flip it up to a 0/5. Need a blocker that can also attack, or want to reset it past a face-down-matters effect? Pay and it becomes a 2/2 again, reusable as many times as you have mana. That recursive flip-flop is the design idea, and it is unusual: most morph cards are one-way, paying their unmorph cost once to commit to the better side. The defender clause is what keeps the 0/5 honest, ensuring the toughness never converts into a clock. What you are really buying is a defensive body that can dodge whichever removal or board state the opponent presents, sliding between a hard-to-kill wall and a disposable two-power creature at instant speed. It is a fiddly, mana-hungry trick, but the toggle is the genuine wrinkle in a mechanic that almost never lets you flip backward.
