So yeah I'd say you definitely need some basic lands for decks that run Blood Moon, Ghost Quarter or even Path to Exile. I did a copy of your deck and had a try at the mana base, I think your ratio for Fetches and Shocks is on point, so I went and removed the check lands for basics and added some Ghost Quarter for Tron match ups.

2x Arid Mesa

1x Blood Crypt

1x Bloodstained Mire

2x Flooded Strand

3x Ghost Quarter

1x Hallowed Fountain

2x Island

1x Mountain

1x Plains

1x Polluted Delta

2x Reflecting Pool

1x Sacred Foundry

3x Scalding Tarn

2x Steam Vents

1x Swamp

1x Watery Grave

So even with the check lands removed you should have enough mana in each colour to play your spells. Let me know what you think? Also was thinking maybe you should add another wincon? If Tasigur, the Golden Fang was to be removed or exiled your only way of winning would be to burn them out or beats to the face with Snapcaster Mage, so maybe a single Elspeth, Sun's Champion for a secondary wincon? Anyways hope this kind of helped a bit :)

Any thought to adding some celestial colonnades as alt. win cons?

Bean17 I think I might add a single Colonnade and Tar Pit, as I've had some difficulty closing games where I don't draw my creatures early enough. The last game I played I had 8 cards left in my library by the time I killed them.

StinjyJumpingJew It looks good, though I have to take the Ghost Quarters out for colored sources. Since I could need literally any combination of my colors out by turn 2 (okay maybe not BW) playing colorless lands isn't a luxury I can afford.

StinjyJumpingJew I decided to take out one of the Kommands for an Avacyn as an additional win con

While I like the Idea i'm not too sure how good this will perform in practicality.

I could be wrong do you have results from testing local tournaments or the like?

This is a cool deck!

Have you considered esper Charm somewhere in the 75? It's pretty sweet as an early game mind rott during the opponent's draw step and decent gas in the late game while most importantly giving another out to blood moon. Lol :D

Gaijin0 Hmm, that's a pretty good idea actually, Esper Charm is a pretty solid card.

I would consider Gitaxian Probe and some of the 0 mana instants. Pact of Negation and Slaughter Pact mostly

would you want to get rid of the more soft counters for more hard counters? for example cut the Mana Leak and Remand and add 3x Cryptic Command? Also possibly cut the Painful Truths and Utter End as well as Electrolyze. In turn adding another Kolaghan's Command and maybe a couple Supreme Verdict?
