Chorus of Might

Green's go-wide instants usually pay you in raw stats: an Overrun for the team, a fight spell for one body. This one folds the whole board into a single pump, which makes it a finisher dressed as a combat trick. The math scales with creature count rather than mana, so the spell is dead weight on an empty board and a kill on a developed one: cast it on a token swarm and the +1/+1-per-creature bonus turns one attacker into lethal damage past blockers, since the trample rider means the defending player can chump only so far before the overflow lands. The design tension is that it counts your creatures, not your attackers, so a board parked on defense still feeds it; the reward is for going wide first and finding the one window where a single unblocked body can carry the count. Compared to the team-wide pumps in green's lineage, the all-in-on-one structure makes it more fragile to a single removal spell in response and more explosive when it resolves, a glass-cannon profile that rewards the player who has already committed the board and just needs a way through.
