Mistfire Weaver

The pitch is the unflip, and the disguise is what sells it. The trigger fires the instant you turn the Weaver face up, and unmorphing is something you can do with priority: the shield comes online in response to a removal spell already sitting on the stack. The opponent points a kill spell at your real threat, you flip the Weaver in reply, and hexproof lands before the spell resolves, so it fizzles for want of a legal target. The protection reaches any creature you control, the Weaver included, meaning one activation can save it from removal aimed at the flip itself and still deposit a 3/1 flier on board. The cost is real and worth stating plainly: to deploy it hidden, then to unmorph, six mana across two turns for a single instant-speed reprieve and a fragile body. What pays for that is the concealment. While it sits unturned, the opponent cannot know whether they are staring at a cheap beater, a combat ambush, or a protection spell held in reserve, and that ambiguity taxes every removal decision they make. This is the archetypal role morph was built to fill: bluff cards that punish the opponent for guessing, where the reveal is the payoff rather than the stat line. The body underwhelms; the uncertainty does the work.
