Hey, I just saw your deck, i think it is a pretty interesting idea, similar to Djeru decks
I have just one question: where are the mana rocks and ramp? With just 31 lands you are going to get mana-screwed 100%. I would choose the Planeswalkers more selectively and get up to 38 lands or include at least 15 cards to ramp, or make something in between. The decks with the least lands that I own do have 33 lands at minimum and 15-17 cards to ramp, because otherwise it does not work. The thing is: you will have to cut a lot of interesting cards, which is always hard, but otherwise you will not get to play your deck, which is worse.
