Gaddock Teeg - Total Shutdown (EDH / Commander)

A fair few routes to slowing down your opponents from doing much. I've included a little bit of ramp to make it to the high end cards just a bit faster.
I've included Tooth and Nail without Surrak, so you'll have to be a bit more creative with your finds (don't rely on haste-y attacks). Included are Kamahl and Elesh Norn, so if there's a board wipe or your opponents are getting a little to feisty you can pick off their lands.

Cute little combo for this deck is Pariah with Stuffy Doll (there are several other indestructible creatures in the deck so there isn't just one target). If you feel just that little bit cheeky, exchange for Guilty Conscience for an infinite damage combo.

Additional locks include Archetype of Endurance with Avacyn to make things extremely difficult to deal with. Platinum Angel is in their half to make it more difficult for your opponents to deal with you (and half for the satisfaction of seeing the frustration on their faces).

As always if you want to make this more competitive lower the curve by removing more of the high end cards and combo pieces and put back in low CMC game stalls/locks.
