You might want to take a look at corpsejack menace.

I personally recommend Wall of Limbs in here. I might just have a personal lice for that card, but it can cause some pretty amazing wins and is a strong defender. I think it would find a home in here quite well. Even without it in there this is a fantastic commander deck! Was thinking of making an Abzan commander deck around Doran, the Siege Tower . Might take some pointers from here.

This deck... WOW. After I was done reading it, I thought is would cost like $1500 or something like that. I don't know How you found the perfect combo of low-priced cards. This deck is just amazing, too.

Kalonian Hydra ? :)

Utopia Mycon

Life and Limb

Looks like board wipes and removal might be a pretty big problem for this deck. With the good amount of outlast you've added, I feel like Cauldron of Souls would be great defense for you.

O GOD I THiNK IM IN LOVE WITH YOU!

You get a +1 just for the name. Oh, and I love the deck too.

Cathars' Crusade works very nice with the outlast buddies. Also works very well with ghave.

What about Llanowar Reborn?

U might want to add contagion engine, Vigor, Juniper order ranger, illusionist's bracers, Phantom nantuko instead of rakshasa deathdealer, Mycoloth instead of nyx-fleece ram, And rings of the brighthearth.

Juniper Order Ranger and Cathars' Crusade are great cards
