What I did here was look at EDHREC, went down the lists of most popular cards, and selected cards that I don't run at all or only in 1 or 2 decks.
The resultant deck is very unfocused, but is amusing enough for me to play, because I'm using cards I don't normally run.
The Sliver Hivelord is simply because it's a 5 color general I haven't ever used; it has nothing to do with slivers, and it's just a vanilla creature in the deck.
Long ago this used to be called the "Anti-Don" deck. At the time it was before EDHREC existed, and I just guessed which cards were popular that I wasn't using.
That old version of the deck ran a lot of wraths and indestructible creatures, so I split that idea into another deck here.
