I'm sorry to hear that.
Nice deck though. Arcane Melee might be good for the sideboard. I use it in my modern flashback deck and works wonders against heavy creature decks. I do, however, need LOTS of mana as I am utilizing Past in Flames and only have a turn for my Flashbacks. Might not balance well in this deck but worth a look.

I'm actually on the verge of ordering this deck...
Also, I think your mana balance is fine.

I love this deck. Great combos. I'm curious, is the mana curve too high/do you not have enough mana often?
Also, quick suggestion: Balefire Liege?

Inquisitor's Flail is fun for exalted too, especially with double strike. Quadruple strike!!!!!! Haha

so much fun. I used to use Hex Parasite for the combo before Gatecrash. Ooze flux made me drool. Check out my deck if you're curious how I use it. Still called Hex Hydra, haha...

No land bro.

Ooze Flux and Protean Hydra are deadly together.

Battlegrace Angel... not that you need more life gain!

Essence Harvest could replace Disciple of Bolas
Guardians of Akrasa is a great card in the deck. Exalted decks lack defence, this helps
Holy Mantle helps against your opponent just chump blocking
Inquisitor's Flail can replace Dark Favour. As you don't attack with multiple creatures and you are often tapping the opponent's creatures, this is a great double-damage card.

Just some cards to look at anyways.

marrow-gnawer
Pestilence Rats (although I guess pack rats are just better)
Ink-Eyes, Servant of Oni maybe not because your mana and mana curve is low. Worth a look
Crypt Rats (have saved my life numerous times)
Squee, Goblin Nabob - I always run out of cards to discard for pack rat. This card solves that problem.
Adaptive Automaton - I've always loved him for mono-creature decks.
Undying Evil would work really well with Desecration Demon

Anyways, just some suggestions :)

Darksteel Myr may be of help. Similar to my deck: http://www.mtgvault.com/izbiz/decks/no-myrcy/
Leonin Abunas or Indomitable Archangel can help with those pesky "destroy target artifact" crap

Few possible suggestions:
Bonds of Faith
Cathedral of War
Silent Arbiter
If you have the money, Sublime Archangel is awesome

Take a look at my exalted deck (B/W): http://www.mtgvault.com/izbiz/decks/exalted-want-2/

Burning Vengeance could be fun :)

Myr Galvanizer and Palladium Myr can give you unlimited mana. Also, Myr Battlesphere could also help

Check out http://www.mtgvault.com/izbiz/decks/no-myrcy/ for my Myr deck :)

Norin the Wary may be of help. Or Crusader of Odric.
Check out my similar deck @ http://www.mtgvault.com/izbiz/decks/human-11/. A little cheaper than yours in terms of mana costs. Those two aforementioned cards help a lot.
