Izzet Prowess is a tempo-aggressive deck that kills on turns 2-3 through spell-pumped creatures like Dragon's Rage Channeler, Monastery Swiftspear, and Slickshot Show-Off — your primary goal is to survive long enough to land Atraxa or Griselbrand via Goryo's Vengeance, which ends the game immediately. Fatal Push cleanly answers their one-drops and DRC before they snowball, while Wrath of the Skies as a sweeper clears a developed board if they flood the table. Thoughtseize comes out because taking resources at sorcery speed is too slow against a deck that can kill you through multiple angles in the same turn, and the life loss is relevant here. Solitude and Ephemerate remain central — Solitude can tempo them out of their attack, and Ephemerate protects your key threats while generating repeated value. Be aware their sideboard brings Consign to Memory and Hurkyl's Recall, which can counter or bounce your Goryo's setup — hold Force of Negation for those interactions on your combo turn.
