Izzet Prowess is a fast, low-to-the-ground burn/tempo deck, so cheap interaction that survives Reckless Rage and Burst Lightning matters. Ray of Enfeeblement kills or shrinks Monastery Swiftspear, Soul-Scar Mage, and Screaming Nemesis at instant speed for one mana. Unlicensed Hearse blunts their Stormchaser's Talent and Arclight-style graveyard shenanigans while growing into a real blocker. Graveyard Trespasser and Sentinel of the Nameless City are too slow and die to the abundant burn, so trim them for faster, cheaper answers.
