Red Deck Wins aims to kill you before your engine comes online, so your primary goal is to survive long enough to chain Snaps and Ephemerates into an unassailable life total. Hydroblast is your best card in this matchup — it counters or destroys nearly every threat and spell in their deck, so bring in all four. Last Breath cleanly handles their one-drops like Voldaren Epicure and Goblin Tomb Raider at a low cost. Stonehorn Dignitary is a game-winning trump: blinking it with Ephemerate or Ghostly Flicker locks them out of combat entirely, buying you the time to stabilize. Cut the reactive counterspells like Negate and Prohibit that are too slow or too narrow against their aggressive, low-curve game plan, and trim Murmuring Mystic since a 2/2 that costs four mana is too slow and Bird tokens don't block profitably against Bushwhacker turns.
