Sliver Highlander???

[ORIN]

Helou guys...

(btw,this is my first thread on this site,so just like to say all respect to you guys,so far best site I know)

moving on,I would be greatfull if I could get some advice on a 5-c sliver highlander.not so much on specific cards but on strategy itself.I designed my deck on a premises that slivers have answer to ewerything. So basicaly I just stuffed in all but worst slivers and a bunch of tutor spells.the mana base is working well so far,though not perfect but it basicaly has all alpha duals,all modern duals,bluff lands,all fetch lands and "any type mana" lands.

Now,I realize it doesnt work perfect like this,however I what I need is a voice of experience whether is it even possible to build a viable hard core sliver deck,or should I start putting in some other HL staples?

enough of that here,I will post my deck list in Deck clinic

thx for the time you will take to response
