Overrunfinisher$0.27A classic green combat pump finisher that turns a wide board into immediate lethal damage, similar to Biomass Mutation's team-wide power boost. It also scales your whole team for one turn, though it adds trample instead of setting base stats.
End-Raze Forerunnersfinisher$0.30A stronger finisher for creature swarms that gives the whole team a huge combat swing with trample and vigilance. It fills the same role of closing games by massively enhancing your board, though it is a creature instead of an instant.
Craterhoof Behemothfinisher$15.16One of the strongest go-wide finishers ever printed, often ending the game immediately by scaling the entire team. It serves the same 'pump the board and alpha strike' function as Biomass Mutation, but at a much higher ceiling.
Triumph of the Hordesfinisher$19.02A lethal team-wide buff that can turn any board into a kill, especially in creature-heavy decks. Like Biomass Mutation, it is used to convert a wide board into sudden lethal pressure.
Collective Blessingutility$1.50A permanent anthem effect that makes all your creatures substantially larger, serving a similar role of boosting your board presence. It is slower than Biomass Mutation, but a good long-term alternative in go-wide decks.
Kamahl, Heart of Krosafinisher$4.58A repeatable team-wide pump effect that acts like a powerful anthem and finisher in creature decks. It provides similar board-wide power scaling, though it is tied to combat and repeatable rather than instant-speed X scaling.
Defiant StrikeutilityBudget$0.09Not a board-wide pump spell, but it is a cheap combat-trick-style green/white adjacent comparison for decks trying to push damage efficiently. Included as a budget-friendly functional alternative in aggressive creature strategies, though it is much narrower.
Rootborn Defensesprotection$0.21A token and creature protection spell that can preserve a wide board for a lethal swing, which overlaps with the combat-finisher plan of Biomass Mutation. It does not increase power directly, but it supports the same go-wide strategy.
