Overcome

Green has handed out flat team pumps at every size since the earliest sets, but a raw +2/+2 has a way of getting stranded against a wall of blockers. The trample rider is what stops that from happening. Once each of your creatures can shove excess damage past a single body, tokens and small attackers stop being chump-blockable, and a wide board that should grind to a halt against a defensive line instead rolls straight over it. That is the pivot that earns the spell its five mana: the math swings from "I need another turn" to "this is lethal now." An anthem that maintains a board is a value card; this one converts a board into a finishing blow. The sorcery-speed restriction is what pays for that ceiling. You cannot ambush a defender with it mid-combat; you precommit on your main phase with the alpha strike already mapped out, exposed if the board gets answered before you swing. That timing keeps a team-wide trample anthem from tipping into oppressive: full price, fully telegraphed, and worth nothing unless you already have the creatures on the table to point it at.
