I looked through one, but it was budget, so this doesn't really fit there.

Please help me fine tune this monster, right now I find myself comboing 10-15 cards, then not running into anything that I can use. I plan on running this at the next T1 tourney here, so any and all help is appreciated. The tourny is 3 proxy, so all my proxies have been marked:

//Red
Wheel of Fortune - Card Draw

//Green
Channel - Fast Mana
Elvish Spirit Guide x4 - Fast Mana
Tinder Wall x4 - Fast Mana
Land Grant x4 - Fast Mana

//Black
Demonix Tutor - Card Draw
Vampiric Tutor - Card Search
Yawgmoth's Will - Semi Card Draw
Yawgmoth's Bargin - Card Draw
Dark Ritual x4- Fast Mana
Cabal Ritual x4- Fast Mana
Tendrils of Agony x4 - Win Condition

//Blue
Time Walk - Turn Advantage
Timetwister - Card Draw
Ancestral Recall - Card Draw
Tmie Spiral - Card Draw

Mind's Desire - Card Draw
Meditate - Card Draw
Tinker - Card Search

Brainstorm x3 - Card Draw

//Artifacts
Black Lotus *PROXY* - Fast Mana
Mox Saphire *PROXY* - Fast Mana
Mox Jet *PROXY* - Fast Mana
Mox Pearl - Fast Mana
Lotus Petal - Fast Mana
Chrome Mox - Fast Mana
Mana Crypt - Fast Mana
Mana Vault - Fast Mana
Sol Ring - Fast Mana
Memory Jar - Card Draw
Chromatic Sphere x4 - Mana Wash & Card Draw

//Land

What should I take out to put in a Tolarian Academy? Also, in a deck like this would it be safe to through in a Charbelcher or 2 as another win condition in case of Crainial Extraction? Also what would be a good sideboard for this deck? I just got back into the game about 3 months ago and don't have alot of the new cards yet.

Again, thank you in advance, any help is much appreciated.
