Anyone have any suggestions on how to improve upon this deck?

im already trying to finish off the rest of my lands with revised dual lands or shock lands as it speeds up the deck tremendously. My biggest weakness right now is the speed. I havent really encountered anything that beats it other than decks that are severly fast.

Slivers really help themselves all the time no matter what situation you get in. I recommend using firewake sliver or heart sliver for some haste. If you can get a hold of it a rare called Defense of the Heart worked wonders in my deck.

Here's a much better mana base, I use it on my sliver deck:
City of Brass
Gemstone Mine
Reflecting pool
Thran Quarry
Grand Colliseum

Then as far as the slivers go, 2 overlords, 1 legion, and since you've got the homing slivers and the overlords, you can go with a toolbox approach, like 1 of everything that is useful, (except you gotta stick with 4 homing, 4 muscle, 4 sinew, 4 gemhide)

Oh and BTW ---> ---> ---> Mana Echoes <--- <--- <--- How about infinite slivers (with the queen), or if you get the mana echoes with the overlord, gemhide, and heart sliver, then you can effectively pull out every non-mana-intensive sliver from you deck and put it into play in one turn! That's a real eye popper!

That's a lot easier to pull off than it sounds, I do it all the time. Once you get the overlord in play, it's inevitable. Even without the mana echoes, the gemhides in cooperation with the heart sliver (which there should only be one of) mean you're pulling and playing a lot of slivers per turn anyway.

theres a neat one called Toxin sliver, that gives all of your slivers deathtouch.
