Mechanozoa
A tempo tool that lets you spend its disruption twice across a game rather than all at once. Pay the reduced cost early and you buy the enters-the-battlefield trigger ahead of schedule: tap an opponent's best artifact or creature, drop a stun counter on it, and hold the 5/5 body just long enough to feel the pressure before it heads to exile. When the board shifts or a fresh threat lands, recast it for full price and stall a second target. The stun counter is what sharpens each half: a plain tap wears off on the next untap step, but a stun counter gets spent replacing that untap instead, so the target idles a beat longer than a simple tapper would earn you. That the trigger reads "artifact or creature" rather than just creature widens the net, catching mana rocks and utility permanents alongside blockers and attackers. The honest accounting matters here: warp does not grant flash, so this is a sorcery-speed creature both times it hits the stack, and the two casts add up to nine mana, not a discount. What you actually save is concentration. Instead of committing six mana in a single turn to a body-plus-trigger, you split the interference across the arc of the game and bank two stun triggers for the patience, an unusually clean illustration of the mechanic pricing one card for two different moments.
