I've seen Manabond suggested before and tried it myself, and my honest opinion is that it's garbage. But if it works for you, all the power to you.
I am not sure if this build takes full advantage of the red splash. You have Anger, which is obviously *the* reason to play red, and REB in the board is solid too. But access to removal is also important. Fiery Temper has much better synergy with the deck than does Cursed Scroll.
I noticed that you are not running Wild Mongrels. I think this is a big mistake.
Anything else I would have to say about this build I've touched on before in the primer written by myself and Brad Granberry. You can find the original
here, and the post-January update
here.
