Jeskai Energy is an even closer mirror-style matchup built around Ocelot Pride tokens and Guide of Souls energy synergies, so Wrath of the Skies is a crucial sweeper to reset their wide board of Cat tokens that our maindeck removal can't handle one-for-one. High Noon slows down their ability to chain Quantum Riddler warps and cheap spells alongside creature plays each turn, which disproportionately hurts their card-advantage engines. Boromir's counter ability is weak since this mirror mostly involves paid spells, and The Legend of Roku is a slower value piece that doesn't match the need for immediate board answers, so both come out. Prioritize racing their token generation with our own while holding up sweeper mana as insurance.
