Fear of Immobility

White's Pacifism-style tempo has always lived on enchantments and instants; this puts the effect on a body that can turn sideways itself. The tap-and-stun rider is a two-turn tempo hit that only escalates against opponents: your own creatures just get tapped (relevant for untap-cost tricks or convoke setups), while an enemy blocker or attacker eats a stun counter and sits out its next untap step. That asymmetry is the design's whole engine, letting a five-mana 4/4 buy a clean attack step on the turn it lands and again the turn after, all while contributing to the board math. The stun counter does the work a repeatable tap-down effect once did, but priced down and stapled to a creature rather than an ongoing trigger: one shot, no recursion, no lock. The wrinkle that separates it from a straight removal spell is that the target survives; a stunned creature is still a threat that comes back online, so the card trades permanence for tempo and a swing in board presence. It reads as combat math more than control, a creature that clears a path and then keeps walking through it.
