Ninja's Blades

Equipment that grants a combat-damage trigger is ordinary; what sets this one apart is that the drain scales off your own hand rather than off the creature carrying it. Draw, discard, and the defending player loses life equal to whatever mana value you just pitched. That turns a normally passive part of a loot trigger into the whole threat: dump an expensive spell and the life loss becomes a haymaker, while a curve of cheap cards leaves it a rounding error. Deckbuilding around it means loading up on costly cards you do not mind discarding, then finding a body worth suiting up. The equip also grants Ninja typing on top of the +1/+1, folding the wearer into a tribe that has always cared about connecting in combat and bouncing home to hand, so the loot-and-drain sits comfortably next to what Ninjutsu strategies already want to do. The catch worth respecting is that the entire package hinges on landing damage: no connect, no loot, no drain. This rewards a deck already committed to attacking rather than forcing one into being. And the Ninja typing pointedly does not supply the evasion the trigger craves, so the sharp part of the puzzle is pairing this with a threat that can already get through unblocked.
