About This Manabase
Marvin, Murderous Mimic is a Colorless commander with a colorless color identity, so any land that produces only those colors is fair game. Our auto-built manabase above starts at the Optimized $100 tier. EDHREC doesn’t yet have deck data for Marvin, Murderous Mimic, so picks are ranked by a land-quality heuristic — Commander staples and the strongest in-budget cycles first (shocks and untapped fixing, dropping to scry and tap-duals as the cap tightens), with the rest filled by basics split across the identity.
Pick a tier above to reshape the manabase. The Budget ($25) tier leans on basics and the cheapest utility lands; Optimized ($100) adds the best mid-priced duals and untapped fixing the budget allows; Unlimited drops the price cap so premium duals and in-identity fetches come in. Filter out tap-lands for faster decks, or pin yourself to fetchable lands for a fetch-heavy ramp shell.
