Boros Energy is an aggressive midrange deck that generates value through Ocelot Pride and Guide of Souls while threatening explosive damage with Ragavan and Phlage. Post-board you want to maximize removal density and sweepers to contain their board development while Narset shuts down their card advantage. Celestial Purge cleanly answers Phlage and Blood Moon, and the extra Wraths give you redundancy against their go-wide plan with Goblin Bombardment tokens. Be patient with Supreme Verdict through their Blood Moon turns and prioritize keeping Ocelot Pride off the table early.
Jeskai Blink grinds through Ephemerate loops with Solitude, Phelia, and Quantum Riddler to generate overwhelming card advantage, while Ragavan pressures your mana. Post-board, Mystical Dispute is exceptional here as nearly every key spell is blue, and Consign to Memory handles their pitch spells and Ephemerate value. Vendilion Clique lets you strip key combo pieces from their hand at instant speed while providing a clock. Focus on resolving Teferi Time Raveler to shut down their Ephemerate shenanigans, and use Orim's Chant proactively to force through your own haymakers.
Affinity deploys cheap artifacts to power out Urza's Saga constructs and Kappa Cannoneer while Emry recurs threats from the graveyard. Your sweepers line up well since Wrath of the Skies can be tuned to hit their entire board, and March of Otherworldly Light exiles key artifacts cleanly. Post-board, Rest in Peace shuts down Emry recursion loops and weakens their graveyard synergies significantly. Prioritize answering Urza's Saga with Prismatic Ending before it makes construct tokens, and save Counterspell for Kappa Cannoneer which is their hardest threat to remove once resolved.
