About This Manabase
Mastermind Plum is a Mono-Black commander with a B 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 Mastermind Plum, 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. The picker always includes Commander staples like Reliquary Tower, Bojuka Bog, Rogue's Passage when they fit your identity — these are nearly auto-includes in any EDH deck. From the catalogued cycles, the picker pulled Bloodstained Mire, Polluted Delta, Verdant Catacombs, Howltooth Hollow , plus 2 more for Mastermind Plum's manabase.
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.
