About This Manabase
Landroval, Horizon Witness is a Mono-White commander with a W 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 Landroval, Horizon Witness, 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, Rogue's Passage when they fit your identity — these are nearly auto-includes in any EDH deck. From the catalogued cycles, the picker pulled Windswept Heath, Flooded Strand, Marsh Flats, Arid Mesa , plus 3 more for Landroval, Horizon Witness'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.
