Hello people,
I'm trying to build an artifact commander deck. As you'll see, lots of Sphinxes.
Very passive deck, I just gain life, and when time comes, I enable beast mode.
Got a combo or two to win in there.

Hope you can give me some feedback on how to improve my deck!

What about putting in a Urborg, Tomb of Yawgmoth?? Maybe use this for most of your swamp base...
