Where's your sideboard and why are you running 1 Underground Sea if there is no black to be seen?

I run a similar list without any black. I like the idea and ever since I made the changes I haven't looked back. There are some major differences between our lists and mine are as follows:

-1 Trike
+1 Duplicant
Duplicant removes their creatures from the game entirely while Trike only deals damage (3 at the most) and sends them to the 'yard, where they can be recovered. If you are Welding Trike in and out for 3 damage to a player per turn you are missing the point of the deck.

-1 Underground Sea
+1 Island
No black so why bother to give Wasteland another target?

-1 Lotus Petal
+1 Mana Vault
Lotus Petal isn't very effective in this deck. It may give you another quick mana but that is only if you get it in your opening hand. It isn't something you Tinker for if you need more mana (I was really desperate) and doesn't put you an Island tap away from activating Slaver (the whole point of the deck). Speaking of Slaver...

-1 Cruicible of Worlds
+1 Mindslaver
For the most part your first Inutuition should be for 3 AKs because the third goes to your hand and should dig you into Thirst or the fourth AK. After that Intution-ing for Slaver, Slaver, Platinum Angel usually says "Good Game" considering that you can pitch whichever one they put into your hand through Thirst, which you will see plenty of since your deck is so thin at this point.

-1 Seat of the Synod
+1 Darksteel Citadel
Indestructable is a good thing. It can still be Welded.

Mystical Tutor should be in there too . Having Tinker whenever you want it is a good thing. Late game pitches to Force. Also I'm trying the 1 maindeck Cunning Wish with a board of:

1 Lava Dart
2 Rack and Ruin
1 Shattering Pulse
1 Pyroblast
2 Red Elemental Blast
1 Fire/Ice (not really sure on this one)
1 Misdirection
1 Echoing Truth
1 Darksteel Colossus
3 Sphere of Resistence
1 Jester's Cap

My version cuts 1 Intution (after 2 they're dead; there's nothing left to search for) and the Library of Alexandria. I never really think about the deck with it and don't really want to put it in. The deck has enough draw but uncounterable draw is a good thing.
