Four and Five Color Aggro brings powerful multi-format threats backed by removal across multiple colors. Your efficient spell-based creature suite in Eddymurk Crab, Hearth Elemental, and Sunderflock trades well against their individual threats. Abrade, Sear, Get Out, and Broadside Barrage expand your removal to handle their diverse threat base. Pyroclasm provides sweeper capability against go-wide openings. Ral, Crackling Wit generates card advantage while applying pressure. Multiversal Passage and Into the Flood Maw are too slow for this pace while Bounce Off is reactive, and Spell Pierce loses value when they have full mana to pay for it.
