Izzet Prowess wins by burying you under cheap one- and two-toughness creatures like Monastery Swiftspear, Dragon's Rage Channeler, and Slickshot Show-Off, so Pest Control's sweep of mana value 1 or less permanents cleanly answers Swiftspear and Mishra's Bauble while Wrath of the Skies scales up to catch Dragon's Rage Channeler and Cori-Steel Cutter tokens. Heartless Summoning's -1/-1 doesn't help against a deck with almost no creatures to cheapen and only shrinks your own Solitude and Overlord of the Floodpits, so it's cut alongside Momentum Breaker, which whiffs against a deck that rarely commits a single important permanent. Play around Consign to Memory-style counterplay by holding up Fatal Push and Solitude to answer Dragon's Rage Channeler or Cori-Steel Cutter before they take over combat math.
