It's a great starting point! This looks like a fantastic deck, and I think you'll have a lot of fun with it!
I will note that Mistbind Clique is extremely strong, except against decks that can go off at instant-speed. I had one game against Abzan CoCo that I was winning, but I got greedy and attempted to Mistbind them on their upkeep. They cast CoCo in response and went infinite.
I will note that you will have a tough time with this deck against aggro, since it's not the strongest against them. I don't have great answers for how you address aggro, but against the decks you listed, I think you'll do fine. Possibly pack your sideboard with more graveyard hate if dredge is something you're going to play much (I recommend Relic of Progenitus personally).
If you find yourself stuck on mana color requirements, I switched from Mutavault to Faerie Conclave because I didn't like all of the colorless mana. I still keep one Mutavault and two Ghost Quarter in my deck though, so your 1-of mutavault may be fine.
I also recommend Boomerang as a "catch-all" card -- it can bounce problem lands, planeswalkers, enchantments, etc -- it's a catch-all answer card that can be useful -- especially in the sideboard.
Your deck looks great -- I look forward to hearing more about how well it performs!
Thanks for the thorough answer! I will get some proper testing done tomorrow night.
In goldfishing, the land base seemed awkward so I made a few changes; namely, I barely have any black spells md so I don't need that many black sources, so I cut a grave and two catacombs, since the first hurts and the latter sucks on first turn. Sometimes I get stuck with two or three lands and mistbinds\swords in hand, so I might consider adding another land or two (possibly conclave).
I have a 3rd Mistbind coming in the mail so I might consider adding it as well at some point. I have to see how it goes, but the idea of a pseudo-timewalk attached to a sizeable flying body with flash is pretty good.
I like Echoing Truth more than Boomerang because I know the dredge players will summon armies of free Vengevines\Prized Amalgams\Bloodghasts, it's fantastic against tokens and also easier on the mana (not that I have trouble hitting double blue, but still).
