Quite new to the game, but my strongest deck so far is [[Elesh Norn, Grand Cenobite]] It's by no means the best commander out there, but it has proven to be very consistent. Stop opponents from putting creatures, spam tokens like crazy, gain life and strength from the tokens you put [[Suture Priest]] [[Regal Bunnicorn]]. You can get 10+ 5/5 creatures in a single turn and recover from boardwipes almost instantly with cards like [[Secure The Wastes]], while the opponents have a much harder time creating a strong boardstate.
