Two-Headed Cerberus

Double strike on a body this fragile is the keyword stripped to its delivery mechanism: 1/2 for means the ability does almost nothing on its own, one damage in the first-strike step and one more after, two total from three mana, a rate no removal spell would ever pay for. That is the point. The card is a vessel, not a threat, and every point of power you bolt onto it gets doubled: an aura, an anthem, a single +2/+0 turns a negligible attacker into a fast clock. The toughness of 2 is the quiet concession that keeps it fair. It survives a stray point of incidental damage but folds to almost any real removal, so the doubled swing has to be set up and protected across turns rather than assembled instantly. Faster double-strike bodies exist, Fencing Ace and Boros Swiftblade among them, and the comparison clarifies what this design is actually selling: not the cheapest access to the keyword, but the cleanest. A bare 1/2 carries no first-strike combat math you have to respect on defense and no evasion that tempts you to swing into a bad block; it sits there as raw multiplier waiting for an investment. The whole design hands you a fragile multiplier and asks you to do the work of making it matter somewhere else.
