Eva_Blue definitely parallels UGb-Threshold. The major difference to me is (and this is not supposed to sound arrogant..) that it is slightly more aggro (Stalker) and slightly more controlish (Deed, EE+Trinket).
I couldn't mws-test it thoroughly since I'm a mac user now, I want to take this to an upcoming tournament and feel it needs some more tweaking, so fire away!

Eva-Blue (Oct. 2008)

4 Tarmogoyf
3 Tombstalker
1 Trinketmage------------debatable choice: Trinket sort of replaces Top#3 and creates a mini-toolbox (EE#2,Top#3,Crypt#4), while being the 3rd 3cmc (2 Deed) for CB. - I definitely don't want more than 1 T.mage because of his lack of speed.

4 Ponder
4 Brainstorm

4 Force of Will
4 Thoughtseize------------instead of 3 Spellsnare and Daze#4
3 Daze
3 Counterbalance
2 Sensei's Divining Top--probably should be a 3-of..

4 Smother
2 Pernicious Deed
1 Engineered Explosives
--> I like this mini sweeper suite, do you?

Land:
4 P. Delta
3 Floodedstrand
1 Bloodstained Mire--fetching the basic swamp_8 fetchies for Stalker
3 Underground Sea
3 Tropical Island
1 Bayou---------------makes the manabase semi-extirpate-proof, not sure about it's definite inclusion..
1 Island
1 Swamp
3 Wasteland----------not perfect here but making Daze playable

SB:
3-4 Krosan Grip
3-4 Blue Elemental Blast
3-4 Diabolic Edict...........(Yap!)
3 Tormod's Crypt
0-3 Flex Slots -----------(Suggestions?..)

Thx 4 reading!
