Mono Red Madness is a fast burn-combo deck that races; Weather the Storm's storm-copied life gain can swing the race by a huge amount since Ruby Storm's own rituals pile up storm count. Flaring Pain stays in the sideboard because it only stops damage from being prevented, which does nothing against their burn. Red Elemental Blast stays in the sideboard since their only blue card, Sneaky Snacker, is never actually cast; it comes back from the graveyard instead, so the counter mode has no target. First Day of Class is cut since this matchup is about surviving to combo off rather than squeezing extra haste damage.
