This is what my manabase looks like
Land (28)
Mana Sources:
1x Bayou
1x Forest
1x Plateau
2x Savannah
2x Scrubland
1x Taiga
Fetch lands:
4x Windswept Heath
1x Verdant Catacombs
'Cycle' lands:
2x Tranquil Thicket
1x Horizon Canopy
1x Secluded Steppe
Manlands:
1x Dryad Arbor
1x Stirring Wildwood
Utility:
1x Dark Depths
2x Grove of the Burnwillows
1x Karakas
1x Thespian's Stage
4x Wasteland
3 important missing pieces of info:
1) 4x Mox diamond - fixing and acceleration, don't hesitate to 'throw away' colorless lands
2) The whole deck can be played off Scrubland + Plateau and all but 3 cards can be played off of any two of Savannah, Scrubland, & Bayou or a Forest+Scrubland. 2 colored mana sources is almost always enough. Over half my deck can be cast off just Savannah as a colored source.
3) I feel comfortable aggressively mulliganing to good hands because Loam, Chalice, and Depths are all ways to make the initial resource advantage not matter.
