Izzet Prowess is a fast aggressive deck that doesn't care about land destruction, so Field of Ruin and one Demolition Field come out. Beza, the Bounding Spring comes in as a life-stabilizing, card-advantage-generating body that blocks well against Monastery Swiftspear and Emberheart Challenger while gaining 4 life if you fall behind. Chandra, Awakened Inferno's -3 sweeps non-Elemental creatures like Soul-Scar Mage and Screaming Nemesis for 3 damage each, and her +2 emblem grinds out a deck that lacks reach outside combat damage. Prioritize your removal (Get Lost, Erode, Avengers Disassembled) on Screaming Nemesis carefully since its damage-reflection ability punishes careless removal.
