Boros Energy is an aggressive go-wide deck relying on Ragavan, Ocelot Pride tokens, and Guide of Souls triggers. Crystal Barricade is a strong wall against their token swarm, giving us hexproof while blanking noncombat damage to our other creatures. Watch out for their two Blood Moon, which can strand our multicolor mana base, so sequence lands carefully and consider prioritizing basics when possible. Haywire Mite is cut as low-impact, though it can exile noncreature enchantments like Goblin Bombardment.
