Pacifism that prepays for its own follow-through is exactly what a medium-speed format with one or two removal commons per color is hungry for. White drafters in TMT spend their early picks looking for an answer to Shredder, Unrelenting and the run of two-color legendary Turtles at uncommon, and the eject button built into the aura answers them on a timeline the deck controls.
Pick band sits P1P3 to P1P5 in any white seat, ahead of Grounded for Life in most boards. Grounded for Life can destroy untapped creatures too, but it pays a premium to do so and wants the target already tapped; Uneasy Alliance does not care whether the bomb ever attacks. RW Equipment wants it most: the deck already spends mana suiting up Foot Ninjas with Bespoke Bō, and parking the lock on an opposing legend while the equipment does the clock work is the cleanest line the archetype draws. WB Ninjas takes it nearly as high and reads the back half differently, since the 1/1 black Ninja is a live creature type for the deck's payoffs rather than a throwaway chump.
The format math: with fixing good and utility lands widely played, the activation comes online by turn seven or eight, which is when the bombs are landing anyway. The real tax is the format's bounce and Disappear effects. A flicker or bounce of the enchanted creature puts the aura in the graveyard, and because the activation is sorcery-speed, you cannot crack it for the token in response. The lock is unconditional; the eject is not. That gap is the only thing keeping this out of the top common slot. Maindeck in every white deck regardless.
