Sliver Overlord toolbox (EDH / Commander)

I've disassembled this deck in november 2017.

Even though Slivers have a bad reputation, they're a really fun tribe to play.
They're not as explosive as Elves or Goblins, but you if manage to get the right 5-7 Slivers onto the battlefield the game will be over.
Knowing when to start playing your Slivers is very important. This deck has some redundancey, but every Sliver is valuable and each loss will weaken your final hive.
Building the right boardstate takes time. You'll have very little board presence during the first couple of turns and will take at least a couple of hits.
But, once you get enough of your protection slivers online the other payers will be hard pressed to stop you.
