Thallid Shell-Dweller
Virulent Sliver

I felt very uncomfortable about this pool because none of my rares were very powerful, and the fat was basically non-existent.  I ultimately settled on playing WUr, and played the following:

White                                                                  Blue
Amrou Seekers                                                     Crookclaw Transmuter
Blade of the Sixth Pride                                          Sarcomite Myr
Fortify                                                                  Spiketail Drakeling
Knight of Sursi                                                      Telekinetic Sliver
2x Lymph Sliver                                                     2x Unblinking Bleb
Marshaling Cry                                                       Whip-Spine Drake
Outrider en-Kor
Temporal Isolation                                                 Red
Watcher Sliver                                                      Conflagrate
                                                                           Ghostfire
Other                                                                  2x Homing Sliver
Calciform Pools                                                      Undying Rage
Dodecapod
6x Island
3x Mountain
6x Plains
Terramorphic Expanse

Miraculously, I lucked out and went 3-0-1 despite playing against better decks rounds 2 and 3.  My round 3 opponent actually had a Sliversmith to complement a sliver contigent which put mine to shame (Sidewinder, Quilled, Spinneret, Fury, Bonesplitter, and I think some others.  I had to side out the TK and Watcher Slivers against him.).  I felt like I was really lucky to do as well as I did with this pool, but do you think I could have built my deck better?

Red, green, and black aren't as interesting as blue and white in your pool.

There are two configurations that I'd go with. One is blue/white and the other is blue/white/splash red. Either would work out pretty well with the main difference is the amount of risk you want to take with the mana base.

UW:

1-cc:
knight of sursi

2-cc:
blade of the sixth pride
infiltrator il-kor

temporal isolation

3-cc:
amrou seekers
outrider en-kor
blind phantasm
sarcomite myr
spiketail drakeling
whip-spine drake

fortify
leaden fists
wipe away

4-cc:
watcher sliver
telekinetic sliver
crookclaw transmuter

temporal eddy

5-cc:
2x lymph sliver

pact of negation

6-cc:
jedit's dragoons

walk the aeons


Land:
1 calciform pools
1 zoetic cavern
9 island
7 plains


16 creatures
18 land
average cc ~ 3.3

This version is very solid. There are multiple flying and other evasion creatures and good ground support with the lymph/watcher slivers and dragoons. The concern comes to the lack of removal; temporal isolation, leaden fists, and pact of negation are the main contenders with the temporal eddy and wipe away being used when necessary.


In the version that splashes red, these are the changes that I'd make from the decklist above:

-1 walk the aeons
-1 temporal eddy
-1 zoetic cavern
-1 plains
-1 island

+1 conflagrate
+1 ghostfire
+1 terramorphic expanse
+2 mountain

This version has a pretty unstable mana base and will probably give lots of trouble 1 in 5 games because of not having the correct mana. However, I'd consider boarding into this configuration if your opponent has multiple problem creatures that are overwhelming your removal suite. Siding in the flowstone channeler could be a strong option also in which case you'd probably want to SB out the calciform pools for an additional mountain.

The blue white version would probably be the best choice because it's not going to lose to itself.
