Mabel's Mettle

Most combat tricks buy one big number; this one splits its buff, and the split is the point. The +2/+2 on a single body is the familiar instant-speed ambush: it eats an attacker or shoves a blocker past its weight. What the second clause adds is a second fight. Sending +2/+2 one way and +1/+1 the other lets the card trade with two creatures in the same combat, punishing a double block or letting a pair of attackers each survive their exchange. The "up to one other target" wording keeps the second buff optional, so the card never rots in hand when only one creature is worth boosting. That elasticity is what separates a spread pump from a taller single-target one: white aggro rarely needs a single enormous creature so much as it needs to win several small skirmishes at once, and a spell that scales its reach to the shape of the board fits a go-wide plan naturally. The rate is modest by design. +3/+3 spread across two bodies for two mana rewards a developed board rather than a topdeck haymaker, which is exactly the tension a combat trick built for a swarm should carry.
