High Noon locks Boros Energy's low-curve aggro plan to one spell a turn, which cuts off their explosive turns of Ragavan, Ocelot Pride, and burn spells being cast together. Wrath of the Skies is a clean sweeper versus their token army (the Cat Warrior tokens from Ajani, the Cat tokens from Ocelot Pride, and the Warrior tokens from Voice of Victory's mobilize) and their small creatures like Ragavan and Seasoned Pyromancer's Elementals. Quantum Riddler is a sturdy 4/6 that survives Galvanic Discharge, but at five mana it is too slow against this fast clock, so it comes out, along with some Ephemerate copies since you have fewer ETB value targets worth doubling up against this fast clock. Keep Solitude and Orcish Bowmasters for their efficient interaction against the go-wide game plan.
