Gruul Deck Critique requested.

Feedback is appreciated.

Basically a Gruul deck that includes unblockables and Varolz, the Scar-Striped.  Basic premise is bloodrush the unblockable then use Varolz to scavenge the bloodrushed creatures and give permanent bump to the unblockable.  I also threw in some Alpha Authority to give the unblockable hexproof.

Thoughts?
