Four and Five Color Aggro brings a powerful multi-color threat suite backed by removal across multiple colors. Your existing Deceit, Requiting Hex, and Bitter Triumph removal package is well-positioned to handle their diverse threats. Annul handles key enchantments and equipment they may bring. Duress strips their best threats and removal from hand proactively. Cruelclaw's Heist steals their most impactful creature and flips the board state. Oildeep Gearhulk and Malboro are too expensive and slow for matching the pace of an aggro deck, Archenemy's Charm is too situational, and Stock Up is cut as too passive when you need to be generating proactive interaction rather than card draw.
