Boros Energy floods the board with cheap creatures like Ocelot Pride, Guide of Souls, and token generators, so a second Wrath of the Skies and the second Supreme Verdict give you more sweeper density to reset a board they rebuild quickly. High Noon is excellent against their explosive multi-spell turns fueled by Ranger-Captain of Eos and Seasoned Pyromancer, slowing them to one spell per turn while your own deck can still function reasonably. Spell Snare is narrow since few of their key threats cost exactly two mana, and Prismatic Ending competes awkwardly with their two-color manabase for converge value, so trim both slightly. Keep Galvanic Discharge as premium removal for Ragavan, Nimble Pilferer and Guide of Souls, and prioritize timing your sweepers around Ajani, Nacatl Pariah's transform trigger and Ranger-Captain of Eos's spell-lock ability.
