Rakdos Madness Burn's creatures are almost all small (Sneaky Snacker 2/1, Voldaren Epicure 1/1, Kitchen Imp 2/2), so Breath Weapon's 2 damage wipes their entire board, Kitchen Imp included, slowing them down while they try to burn you out with Fiery Temper and Lightning Bolt. Weather the Storm's lifegain is critical against a deck built to drain and burn you directly (Alms of the Vein, Vampire's Kiss, Grab the Prize), buying time to stabilize. Cut slower, higher-curve cards that don't help you survive the early onslaught for this cheap interaction and life buffer. Keep your efficient beaters to pressure them back once their burn is spent, and be aware that Breath Weapon will also kill your own Arbor Elves, so time it accordingly.
