Mono Red Madness wins by burning you out fast, so lifegain from Weather the Storm and Pulse of Murasa buys extra turns while Pulse also recurs a creature. Breath Weapon deals 2 damage to each non-Dragon creature, sweeping Voldaren Epicure, Kessig Flamebreather, and Guttersnipe, which are the key payoffs that must die on sight. Cut the slower, clunkier cards like Annoyed Altisaur and the Repurposer/Rumble package since they do nothing to stop the damage race. Keep your efficient mana ramp and cheap creatures to pressure them back before they assemble lethal.
