Murderer's Axe

The equip cost is the whole conversation here: every other +2/+2 Equipment pays in mana, and this one asks for a card from your hand instead. That swap matters more than the flat four-to-cast price suggests, because it reframes the question from "do I have the mana" to "is this attacker worth a card." For an aggressive deck that has run dry, discarding a dead land or a clunky spell to keep a creature swinging is real value; for a midrange deck holding answers, the card-disadvantage stings exactly when you can least afford it. The discard also quietly rewards decks that want cards in the bin anyway, turning a downside into fuel: madness pays off the pitched card immediately, while flashback, delirium, and reanimation each read that discard differently than a fair deck does. As a static buff the rate is unremarkable, but the cost structure is the design idea, an Equipment that taxes hand size rather than the manabase, and the flavor of paying for your weapon with something other than gold sits cleanly on top of it. It is a niche tool rather than a staple, sharpest in the decks built to treat an empty hand and a full graveyard as features instead of failures.
