[EDH] Sedris, the Value King

The cut-throat meta that's kinda developed (mostly between me and Rod) in the more recent EDH games has begun to bore me. It was fun for a little while, but I'd rather keep overpowered crap to other formats, so I decided I'd go with a rather casual take on an EDH deck. Naturally there's some powerful cards, it wouldn't be EDH without them, but I'm not exactly playing Dream Halls, Enter the Infinite, Omniscience and casting my deck. In fact, I made sure not to include any of those, and the only combos I do have are ones I have no interest in actually using. I also felt that my EDH decks are too spell heavy, and my Teneb deck just has stupid tunnel vision and no real interaction with anything, so without further adieu: Spells-on-a-stick Sedris!
