Agate-Blade Assassin

A two-mana attacker built to punish decks that try to sit behind blockers. The 1/3 body is the whole point: three toughness survives most one-drop trades and small removal, so the drain trigger keeps firing turn after turn rather than getting mopped up the first time it swings. Because the life swing keys off attacking rather than dealing combat damage, the loss-and-gain resolves whether the creature connects or gets chumped, which quietly makes the toughness matter more than the power. That turns a body too small to race into a persistent two-point life swing every combat, the kind of incremental drain that lifegain-and-attrition decks want stacked several copies deep. The design belongs to a long line of small-bodied attackers that convert combat presence into reach: not a threat that ends games by itself, but one that taxes the opponent's life total for the crime of leaving up a blocker. Its ceiling is arithmetic rather than explosive, which is exactly the point.
