Boros Swiftblade

Double strike on a body this cheap is the whole gamble, and everything else about the design exists to make that gamble pay off. A 1/2 hitting for two on its own is barely a clock, but the keyword multiplies every point of power you can add: a single +2/+0 turns this into six damage, and any combat trick or anthem gets counted twice at the moment of contact. A double-striker priced this low has to be balanced somewhere, and the 1/2 frame is where the cost lands. Give it a survivable body and the multiplier becomes oppressive, so the fragility keeps it in check: it dies to a sideways glance the instant the pump spells run dry. The play pattern wants a deck treating this as a delivery vehicle rather than a creature, with equipment, auras, and temporary buffs converting a small swing into double its value. The aggression of this color pair has always been measured in tempo rather than card advantage, and a cheap pre-combat threat that doubles your investment expresses that risk-forward identity cleanly. Left unanswered, it ends games fast; answered at the wrong moment, it costs the opponent a removal spell on a one-power creature. The whole card lives in that exchange.
