Iggy Pop is a fast combo deck that wins by chaining Ill-Gotten Gains loops with Lion's Eye Diamond and Cabal Ritual to fuel Brain Freeze for a lethal storm kill, often as early as turn 2-3. Your primary disruption is speed — apply pressure with your madness threats so they can't goldfish freely — and Tormod's Crypt, which hoses the Ill-Gotten Gains recursion engine by exiling the graveyard in response, breaking the loop. Compost turns their heavy black rituals and Polluted Delta fetches into card advantage, helping you refuel while racing. Savannah Lions and Sylvan Library come out because Lions doesn't pressure fast enough to matter and Library is too slow in a matchup where the game ends by turn 3-4; your discard outlets (Wild Mongrel, Tireless Tribe) remain critical for deploying Arrogant Wurm and Basking Rootwalla at flash speed to threaten lethal before they combo off.
