4 Bloodstained Mire
4 Wooded Foothills
4 Badlands
3 Taiga
6 Mountain
1 Swamp
You'd definitely want 22 lands, and probably 8 fetches. Depending what cards you're running maindeck (Wort, Weirding, Hooligan?) and sideboard (Therapy, Grip?), and whether Wastelands are present, you can decide whether you need the off color basic. I personally like it, but it could just as easily be another Mountain.
Alternately, you could try adding Ancient Tombs to the manabase (-2 Mountain, -1 Swamp maybe). I think Eldariel had experimented with that in the past, and I messed around with it for a bit. It speeds the deck up a bit (dropping turn 2 Matron, turn 3 Ringleader is pretty sweet, as is a turn 4 SGC), but weakens your matchup against aggressive decks and the mirror. If you're not running any Wastes or Ports, Tomb might be a good option to consider.
