Zero Cost Attack

[Suortaw]

I am trying to play off of the concept of a quick kill combo of: land + Spirit Guide -> Flash -> Protean -> don't pay it's upkeep -> play all artifacts, Disciples & 2 Carrions -> sacrifice artifacts to Carrions -> Disciples do huge damage -> attack with Carrions -> Win!

Thoughts?
