Mono Red Rally wants to dump its whole hand and swing for lethal in one turn, so Weather the Storm's storm-copied life gain is excellent at absorbing an alpha strike, and Drown in Sorrow's -2/-2 wipes their entire board of 1/1s and 2/2s (Burning-Tree Emissary, Clockwork Percussionist, Voldaren Epicure, Goblin Bushwhacker, and Goblin Tomb Raider all die) before Rally at the Hornburg can close the game. Troublemaker Ouphe can bargain away a token to blow up Inventor's Axe, denying a key pump source. Cast Down and Pestilence are too slow or ask you to tap out into their hyper-aggressive curve, so they come out in favor of proactive life gain and a true sweeper; Fanatical Offering is cut since you need bodies and life total, not card selection, against a deck this fast.
