SUrprisingly, this works. I've seen it being used to good avail. I just think you need some Kor Skyfishers in there, to bounce Cartographer. And, of course, that the deck is cute and can catch some people off-guard, bit it'll still roll over to most tier 1 decks. This being said, it IS a nice metagame call if you're expecting to face Naya and Jund, mostly, and can't build either one yourself.
