This seems like a very interesting format. So the Entire deck and sideboard can't exceed 10 bucks? How do you handle cards that have a printing that is say .80c but a different printing that's .50c?

I would shift from Aura and go more heavy on Equipment so you could run Kemba, Kha Regent. More equipment also means you could run Vulshok Battlemaster. Equipment is also a safer bet because 1 Smother or the l i k e s, etc loses you all your aura's. Where as equipment has to be dealt with individualy with a few exceptions

Some equipment for you

Silver-Inlaid Dagger, Avacyn's Collar, Harvest Hand  ^Flip(Kind of), Obsidian Battle-Axe.

I think it would be better to lean more into the equipments rather than the auras because none of your creatures are Hexproof so its a pretty big hit if they die. Plus, Sram, Senior Edificer is only 1.49$ so you still have a decent amount left even of you splurge for two of them. Than I would down the number of dudes a little but an replace them with equipments. Lastly I don't think Hazoret's Favor means all that much because it would be better in my opinion to get another dude rather than giving one a small bump. I love what your doing though and the format sounds kind of fun.

I love valduk. Nice to see someone building around him.
