About This Manabase
Scion of the Ur-Dragon is a WUBRG commander with a WUBRG color identity, so any land that produces only those colors is fair game. Our auto-built manabase above starts at the Optimized $100 tier and ranks every pick by how often real EDHREC decks actually run it — so shocks and fetches show up where the budget allows, dropping to scry lands, gain lands, and tap-duals as the cap tightens.
Pick a tier above to reshape the manabase. The Budget ($25) tier mirrors what budget-deck players actually run — mostly basics and the cheapest utility lands; Optimized ($100) shifts to the “default” EDHREC variant with shocks, fast lands, and a couple of fetches when the budget allows; Unlimited uses the expensive-variant data — originals, full fetch suites, and premium duals appear when in identity. Filter out tap-lands for faster decks, or pin yourself to fetchable lands for a fetch-heavy ramp shell.
