Sarcomite Myr

The body is fodder you pay to sacrifice: a 2/1 whose two activated lines both ask for two generic on top of the blue you already spent, and whose more meaningful line cashes the creature in for a single card. The flying option ( for evasion until end of turn) keeps the body from being strictly worse than a vanilla creature you intend to sacrifice anyway, but the real function is the second ability, which turns a stranded attacker into a fresh draw once the board has stalled. This is the artifact-creature-as-deferred-cantrip school of design: a body that participates in artifact-matters counts while it lives and replaces itself when it dies, two roles bridged by a creature that is engineered to be expendable. Nothing on it is free, and that cost discipline is what defines the card more than any aggressive ambition. It wants to die at a moment of your choosing, and the flying activation is mostly there to give the chassis something to do on the turns before you decide to feed it to your own draw step.
