Saw you post in the forums- I think you should jam as many coin flips into this deck. He's indecisive and what do people do when they can't decide? they flip a coin or let someone else decide.
Planar Chaos
Viashino Sandswimmer + Chance Encounter - dump all your mana into swimmer than go to town flipping coins lol.

Krark's Thumb to better your odds.

trixster87:Thank you!

I think a small amount of that will be a lot of fun, a nice spice for the deck. but I don't wanna focus the entire deck on it. Ithink there are better commanders for that and I really wanna (try to) do something super cool that only Yuan Shao, the Indecisive can do.

So do you realize that with the right mana base out, you get infinite combat steps using the B/G sword and Aggravated Assault? Because that is OP as hell.

TheRedGoat Oops.

Oh well, now it's really a commander deck!
