The Mss. got me the Premium Slivers Deck, and I built it from there. I think it's pretty solid, and it's is very fun to play :p
I've contemplated a bit between the general(s), either Sliver Legion , Sliver Queen or Sliver Overlord .I've chosen the Legion finally, because as an castable whenever-i-can Coat of Arms seems too good to pass up. I might change my mind, because the Sliver Overlord can tutor-up which-ever Sliver you might wanna go get... but I've tried to take care of this through some spells such as Tunnel Vision , Survival of the Fittest , Vampiric Tutor , Demonic Tutor , Diabolic Intent , Wild Pair , while then profiting from the Coat of Arms effect the Sliver Legion keeps on giving.
Amoeboid Changeling for notorious shenanigans with Sliver Overlord .There's a good bunch of from-graveyard-to-hand or to-battlefield for making Tunnel Vision more awesome in this deck, as well as reaction to boardwipes.
For the Mana-base, I've brewed the best I could with lands that I actually own. Sure, you can start putting in oldskool duals and the fetchlands but, yeah I feel this suffices and doesn't force me to go through multiple thousands of bucks.
