Rakdos Madness Burn is even more aggressive than Mono Red, adding Alms of the Vein for direct life drain alongside the burn suite, and they can kill you from a relatively high life total with chained madness activations. Healer of the Glade is your highest-priority sideboard card here — three copies provide enough life cushion to survive the early turns and reach the combo window, since each trigger can offset a full burn spell's worth of damage. Fume Spitter picks off their 1-toughness madness enablers and discard outlets, disrupting the chain that enables Alms of the Vein and Fiery Temper at discount. Flaring Pain is a hedge against any Weather the Storm copies in their sideboard, ensuring the Lotleth Giant drain resolves for lethal rather than being dampened. The artifact removal and hand disruption pieces come out entirely because this matchup is a race decided by life total math, not interaction.
