Neurok Replica

A 1/4 body is the giveaway: this was built to sit in front of an attacker, soak a hit, and then trade itself for a tempo swing when the moment is right. The Replica belongs to a cycle of artifact creatures that each fold a one-shot spell into a defensive shell, and this one packs a Boomerang on its way out, bouncing any creature for plus the body it sacrifices. The structure rewards patience over urgency: the wall asks nothing until you want it to, holding the ground until you have both blue mana and a reason to fire, then converting its toughness into an unsummon at instant speed. Because the ability sacrifices the creature as a cost, it can chump-block first and still cash in the bounce on the way to the graveyard, squeezing two uses out of one card. There is a catch the artifact frame disguises, though: strip the blue mana away and the ability sits idle, just a three-mana 1/4 with nothing to do. The Wizard-on-an-artifact framing makes it look color-agnostic, but the card only earns its keep once blue is on board to fund the activation. Until then it is an inert blocker, and the whole design hangs on getting to that . It is quiet, resilient removal-on-a-stick wearing a wall's clothes, and it trusts the body to buy time before the ability ever fires.
