I have been thinking about making the curent version into 5-color. I personally think that it whould improve the deck so much. With bazaar + Uba we each turn can dig for our bombs or fattys + we can shearch. We have a much more viable sideboard, especially against Oath. It already have been shown that it might work, even with an clearly not optimal list (not saying that mine is :
http://sales.starcitygames.com/deckdatabase/displaydeck.php?DeckID=15562

Here's my curent list:

5-color Uba Stax:

lands and manabase - 29 cards:
4 Bazaar Of Baghdad
4 City Of Brass/Tempo ice brigde, whats best?
3 Gemstone Mine
4 Mishra's Workshop
1 Strip Mine
4 Wasteland
9 mana acelerators

Creatures - 9
4 Goblin Welder
1 Karn, Silver Golem
1 Triskelion
1 Sundering Titan
2 Gorilla Shaman

Locks -15:
4 Smokestack
4 Chalice of the Void
1 Trinisphere
3 Uba Mask
3 Crucible of Worlds
3 Tangle Wire

Bombs - 4:
1 Ancestral Recall
1 Balance
1 Demonic Tutor
1 Tinker

Sideboard:
3 Choke
3 Ray of Relevation
3 Viashino Heretic
2 Darkblast
2 Tormod's Crypt
2 Seal Of Cleansing

We lose:
4 Barbarian Ring
3 Mountian (we lose some land stability, but will it really hurt us? I don't think so)
3 Null Rod (clearly a problem, but I think the bombs we can replace it with are better)
some SORs (good card but couldn't fit it in)
2 Duplicant (who cares, we got better fattys)

We get:
Karn and Trisk (both explosive creatures that i really think would improve the deck)
Balance (think you know this one)
Tutor and recall (think you know this one)
Tinker (always good )
and a much more viable sideboard with much more metagame choises.

Open for suggestions.

Before the Wires I were playing this:
1x Wheel of Fortune
1x Grim Monolith
1x Lotus Petal
1x Sundering Titan

The biggest problem with my build is that it's need to have Workshop to perform optimal.

1 Game vs Gift's.

I get early Uba Mask out, and for the next three turn he draw's counter. And I start building up a lock with atleast 1 of each lock component, and he scoops.

1-0

After sideboard we start again i resolve early smokey followed up by Crucible, then playing Tangle Wire (that actually won the game for me because the next 3 turn he was tapped out. And during these three turns i drop 2 Sphere of Resistance and he scoops.

2-0

Game 2 vs Oath

I start up playing SoR. He plays land 2 mox and lotus, go. I waste his land and play Null Rod. On my next turn i play Uba, and next turn again smokey followed up by Crucible. He scoops.

1-0

He starts, playing turn 1 Oath + Orchard. I get rushed.

1-1

I start, playing Chalice 0 and sphere. He plays land, go. I draw anohter Chalice, and play it for 2. Next turn I get Crucible + Waste lock. I draw Welder. And for the next many turns I just beat 1, go. And at last he scoops.

2-1

Game 3 vs. Oath (again but not the same guy)

First game I win, by playing Chalice 2, Crucible + Waste lock. Followed up by tangle and Uba. He scoops some turns later. But didn't see a sign of power.

1-0

First game I didn't see a sign of power, so I make this terrible decision take all my anti mox hate out. And side in my Oath hate. He starts Orchard + Mox (oh... he had power). I play Smokey, go. He get's first Angel, Time Walk. Extra turn anohter angel and I'am dead.

1-1

Side all mox hate back in, and hate myself for my big mistake. He has a hell lot of counter and duress. and removes all my dangerous lock pieces. And some turns later he find's Oath, and I die.

2-1

Game 4 vs Cool Cookie non-powered mono-black discard the rack deck.

He plays turn 1 The rack, and I kept an hand Uba, Chalice, Null Rod, some lands i cant remember... too bad.
He won that game.

0-1

Next game turn 1 Chalice for 1, with The Rack gone he basicly loses, because I just keep back upping my lock components.

1-1

He starts but dont play The Rack, Turn 1 Chalice for 1, Turn 2 Chalice for 2, Turn 3 Chalice for 3. Some turns later he realises "hm.. I cant win " scoop.

2-1

That's the matches i can remember.

Tangle Wire is an amazing card in Uba Stax nearly every time I resolved it, I just won that game.
So please don't dumb the card, just because Vroman hasen't fully confirmed the card yet.
It makes the deck so much better (even in non-powered builds ) because nearly every time you resolve it you get time time to find your most important lock pieces. Not to mention all it ohters synergies.

The list works for me, because in a other turnament I got 3rd place. I understand that you think it looks very unstable, because of Null Rod/Gorilla Shaman/Chalice for 0 don't harm myself, I can take total control of the game, with my extra lock piece that the powered version dont have. I'am not saying that my build is better than the powered version (not at all), but it works until i have got the money to buy power.

We Were about 20 people i think, nearly everyone (but me) got full power. I know it wasn't the biggest turnament but here is the deck list:

Locks/semi locks:
4x Uba Mask
4x Sphere of Resistance
3x Null Rod
1x Trinisphere
4x Tangle Wire
4x Smokestack
4x Chalice of the Void
4x Crucible of Worlds

Creatures:
4x Goblin Welder
2x Duplicant
2x Gorilla Shaman

Mana base:
1x Sol Ring
1x Mana Vault
1x Mana Crypt
4x Mishra's Workshop
4x Wasteland
1x Strip Mine
4x Barbarian Ring
3x Mountian
4x Bazaar of Baghdad
1x Tolarian Academy

SB:
2x Maze of Ith
3x Red Elemental (Dont like this card myself, but didn't got anything to swith it with that day)
2x Tormod's Crypt
2x Duplicant
3x Jester's Cap (lot of Oath in my Meta)
3x Viashino Heretic

Here last saturday, I were going to a non proxie turnament here in Denmark. Just before I went to the turnament i decided to take a look at the forum's. Then I saw Evenpence's acitle with the edia to fit Tangle Wire in Uba Stax (Btw. I have played Uba Stax myself since the first time I first saw it). I liked the idea and decided to fit in 4x Tangle Wire in my "Non powered Uba Stax build, tough with Shop's and Bazaar's", and the reason why I play non powered: I'am only 14 and running out of money. And with nearly no testing of Tangle Wire in the deck, I won the turnament .
