I fail to see how this deck would be any better than regular GAT. The Kobolds are basically dead draws unless you have a Skullclamp in play and even then you would have to pay 1 to turn it into something useful (2 cards).
Looks to me as if more Brainstorm-esque cards (Sleight of Hand, Opt, Serum Visions) in the main deck would do the same thing, but with more consistency. The Skullclamps could then be removed to get some extra slots...
To me, this deck list looks like a pile
