Scorn-Blade Berserker

A body that does nothing in combat and everything for the deck around it. The 0/1 frame is deliberate: this is a payload, not an attacker. Backup on a creature with no relevant stats of its own turns the mechanic into a pure targeting mode, since parking the counter on itself accomplishes almost nothing. The whole design points the +1/+1 counter (and the granted sacrifice-for-a-card ability) outward, onto the creature you actually care about. That granted ability is the payoff: for the turn, whatever you counter can cash itself in for a fresh draw, converting a creature about to trade or die into a replacement. On the Berserker itself, the sacrifice ability is permanent, so the floor is a one-mana body that eventually becomes a card, chip-value insurance an attrition deck wants at the bottom of the curve. The interplay is the point: a fragile enabler that hands a stronger creature both a counter and an escape hatch, then remains available to bleed itself for a card when the board stalls. It is a modest piece built to be one line in a longer sacrifice-and-draw chain, valued for how cheaply it keeps the cards flowing rather than for anything it threatens to do on its own.
