Your deck seems great and fun to play, The only thing is the mana curve, you don't seem to have alot of first draw.

You can always trade in your Sigil of Sleep for a Death Pits of Wrath. Here's a neat little combo with your pemmin's aura: Aphetto Alchemiste + Pemmins Aura + Gilded Lotus + Any wizard you've got = infinite tim!

Here's a better combo for you:
Gilded Lotus + Aphetto Alchemist + Pemmin's Aura + Suq'Ata Firewalker = infinite damage to creatures or players. Add in Death Pits of Wrath + Statecraft. And use Charisma for indestructibles.
Use a Demonic Tutor + Mystical Tutor + Fabricate and some Brainstorm's to speed thing up.
And don't forget Drowned Catacomb.

Trade your Freed from the real for Aphetto alchemist. Trade your Neko-te for Charisma. Take out 2 Extraplanar lens and add in 2 Gilded lotus (combo: Gilded + aphetto + pemmin's) You can tim your opponents to death in one turn if you have ths combo. Take out your Hankyu and put in 2 Death pits of wrath and 2 Statecraft. Remove your cancel and add in either 4x Death blow or 2 isochron scepter and 2 manaleak. The Deathpits of wrath is to kill off other creatures, and the charisma is to steal indestructible creatures from your opponents!

Trade in your Black Vice for an Iron Maiden.

All this deck is missing to make this perfect is a Statecraft a Death Pits of Wrath, and a couple of Fog Banks. Trade in Prodigal Sorcerer for Suq'ata Firewalker's.

humility, icy manipulator and Isochron scepter with: -holy light -orim's chant or -zealous persecution.
Low casting cost, quick, and painful. You can even add in a Caltrops. For creatures...you can consider either Godhead of Awe, Razor Golem, Wall of resistance, soul warden and nomads en-kor. And you can even throw in Ajani Goldmane and/or Elspeth, knight errant planeswalker. Glorious anthem is perfect, never thought of it. Enlightened tutor is a good way to get your combo out quickly. But Charge across the araba, might slow you down. Morale is also a good instant to have. Otherwise, very good deck, and fun to play with. It's the closest you'll get to a white control deck!
