Jeskai Energy combines Guide of Souls and Ocelot Pride's energy/lifegain engine with Ajani, Nacatl Pariah's counter synergies and Ragavan, Nimble Pilferer pressure. Engineered Explosives set to one charge counter sweeps away Ragavan, Guide of Souls, and Ocelot Pride before they snowball into a wide board. Giant's Boulder is cut since it's too slow against this aggressive, go-wide curve, while Warping Wail stays in to exile their small creatures (Ragavan, Guide of Souls, Ocelot Pride, and Cat Warrior tokens). Your removal suite (Kozilek's Command, Dismember) and Trinisphere remain important to answer their cheap efficient threats and tax their curve.
