A 3rd Blood Moon is strong against Izzet Prowess's nonbasic-heavy manabase of Steam Vents, Scalding Tarn, Fiery Islet, and Wooded Foothills. It turns their nonbasic lands into Mountains, which cuts them off from blue for Preordain and Expressive Iteration and slows their explosive starts. It is worth the swap given how fast this deck is. Wrath of the Skies sweeps their small creatures like Dragon's Rage Channeler, Monastery Swiftspear, and Slickshot Show-Off for a modest energy investment, resetting their board after they commit to the attack. Thraben Charm's damage mode depends on how many creatures we control and can be blunted by Mutagenic Growth or prowess triggers in response, so cut it for the sweeper. Static Prison only exiles a permanent for as long as we can keep paying energy, so it is a temporary answer against this deck and we can trim 1 copy. Keep Galvanic Discharge as premium interaction against their cheap threats.
