Jeskai Energy fills the board with small creatures and tokens via Ocelot Pride, Guide of Souls, and Goblin Bombardment sacrifice fodder, making Wrath of the Skies a strong sweeper to reset the board once you pay enough energy. Celestial Purge answers Ragavan or any other red permanent like Galvanic Discharge's controller's creatures cleanly. Force of Negation is less impactful since much of their power comes from creatures and recurring triggers rather than a single key spell. Keep Solitude and Prismatic Ending as your sharpest tools against their efficient one and two-drops.
