Jeskai Energy is another fast aggressive deck built around Ragavan, Ocelot Pride, and Guide of Souls with efficient removal like Galvanic Discharge, so Summoner's Pact's delayed cost is too risky against their tempo and interaction. Dismember kills their small creatures cheaply even when mana is tight, hitting Ragavan or Ajani, Nacatl Pariah before they generate value. A fourth Boseiju helps answer their nonbasic lands and Goblin Bombardment, which is an enchantment. We keep our proactive ramp plan mostly intact but trade the slowest, riskiest card for efficient interaction.
