Futurist Operative

The whole design is a shapeshift welded to the tap symbol, and the interesting part is how you can use both faces on offense in a single attack step. Sitting untapped, this is an honest 3/4: a body that trades up and blocks like it belongs on defense. Tap it to attack and it becomes a 1/1 Citizen that can't be blocked, so it walks past whatever wall the defender has built. The line most players miss is what happens after blocks: with the evasion having already done its job (no blockers get to be declared), you spend to untap it before combat damage, and the unblocked attacker connects as a 3/4 rather than a 1/1. The while-tapped shrink is the entry fee for unblockability; the untap ability is how you buy your way back out of it, at instant speed but never for free. That same untap is also your defensive lever on the opposing turn, turning a spent attacker back into a blocker. The inversion runs in both directions: the card that wants to attack is small and slippery, the card that wants to hold ground is large and grounded, and they are one permanent flipping between states on demand. It doubles as a clean unblockable enabler for anything that cares about connecting: saboteur triggers, combat-damage payoffs, and effects that key off tapped creatures all turn on the moment it turns sideways.
