Blizzard Brawl

Fight spells live and die by the damage math, and the tax on green's version has always been the same: your creature takes the return damage, so you win the exchange and then hand the survivor to the next removal spell or lose it to a crack-back block. This one buys its way out of that tax with a snow threshold. Meet three snow permanents and the fight stops being a trade at all: your creature swings for one extra and cannot die to the damage it takes, so their creature dies and yours walks away untouched. That indestructible clause converts a symmetric fight into a one-sided removal spell, and it does it for a single green mana. The cost is buried in the deckbuilding rather than the mana: you commit to a snow manabase to unlock the good half, and if you fall short of three permanents, you are casting a plain fight spell that puts your own board at risk. It is a clean piece of incentive design, one that turns the snow-permanent count into a resource worth tracking rather than a flavor tax. The sorcery timing is the honest limit; you cannot hold it up as a combat surprise or an instant-speed blowout, so the removal happens on your turn, when you have already assembled the pieces, and never as a reactive trick.
