Alley Assailant

The whole design lives in the moment of the flip. Cast face up, this is an on-rate 3/3 that walks in tapped, no evasion and no payoff, a plain body whose only purpose is to make the interesting version plausible: the anonymous 2/2 with ward sitting face down across the table. The disguise cost is where the ambush math starts. Pay three for the morph, hold up six mana, and the turn you unmask it the drain fires as a combat surprise, three off their total and three onto yours at exactly the window an opponent has committed blockers. That six-mana flip is steep, but it buys the informational edge every face-down card trades on: the defender cannot know whether the 2/2 is a chump or a six-point life swing, and the ward tax makes cheap removal answer it at a loss. Stapling the effect to the turn-face-up trigger rather than an enters clause is the discipline here. You cannot blink it, you cannot recast it for value, and the drain happens exactly once, on the reveal you chose to pay for. It rewards patience over tempo and punishes an opponent for guessing wrong about what a nondescript face-down creature is holding.
