Shandalar Sliver Deck

[doenerchef]

What is your ideal Shandalar Sliver deck?

My idea was to start out with the color that provides most Slivers, which in Legacy is green, but in Shandalar is white (because many of the green Slivers are not available or relatively poor/too expensive in mana cost). So I settled for a G/W deck that I subsequently upgraded to G/W/U. This is my current composition:
4x Savannah
4x Tundra
4x Tropical Island
4x Flooded Strand
2x Mox Emerald
1x Mox Sapphire
1x Mox Jet (until I find Mox Pearl)
4x Sidewinder Sliver
4x Plated Sliver
4x Sinew Sliver
4x Muscle Sliver
4x Predatory Sliver
4x Venom Sliver
4x Crystalline Sliver
4x Galerider Sliver
4x Metallic Sliver
2x Harmonic Sliver (so I'm not completely helpless against Prismats)
2x Swords to Plowshares (for generating lives in Dungeons)

Am I carrying any dead weight in your opinion? As you can see, I really like the 1-mana Slivers. I am considering a 5 color Sliver deck, but I don't think black and red have much to offer, honestly. Haste would be nice, but not worth adding more problems with mana availability, I think.

I am considering to build a larger deck (to prevent me from running out of cards to draw) with basically all the good Slivers in it (i.e. all those with no more than 3 converted mana cost plus maybe the 5-color slivers for fighting against Azarkon (and for the last castle, I guess).
