Boros Energy is a fast aggro deck that pressures us with Ragavan, Nimble Pilferer and Ocelot Pride before we can assemble Living End, but our large cycling threats backed by Force of Negation give us strong protection on the combo turn. Their primary post-board disruption is Rest in Peace, Damping Sphere, and Vexing Bauble — Force of Vigor answers all three for free and also hits mainboard Blood Moon, Goblin Bombardment, and Elegant Parlor. Foundation Breaker and Ingot Chewer cycle into the graveyard for free and clean up any surviving artifacts or enchantments the moment Living End resolves, making it very difficult for them to maintain hate through the combo turn. We cut Wistfulness, Brazen Borrower, and Sink into Stupor as our weakest flex pieces — bouncing a single creature is far too slow against a wide board, and this is a matchup we win by racing to combo rather than trading resources.
