Ruby Storm has no blue spells or permanents, so Red Elemental Blast and Pyroblast are not functional here — this matchup is a pure race where you need to be as fast as possible before they go off with Seething Song and Desperate Ritual into a storm finish. Instead, prioritize lowering your curve and maximizing early damage; Sazacap's Brew and Highway Robbery are too slow when the opponent can kill from a stalled board state once they combo off, so trim them for more direct burn access. Guttersnipe is vulnerable to their Breath Weapon-less removal suite being light, but as a 2/2 it can die to blockers before paying off, so one copy can come out for speed. Mulligan aggressively for fast starts and race before their engine comes online.
