I swear by 1 land. The deck is so consistent as it is, I see no reason to lower the probability of the belcher kill SIGNIFICANTLY in order to make it more consistent. I will say outright that I haven't tested 2-land very much, but I have been more than pleased with this build. Everyone I know who started with 2-land is now playing 1-land.
In tournaments with over 40 people I have top eighted 4 out of 6 of them with this deck. Either I am lucky, have dumb metagames, or this deck is good.
My board is for an unknown metagame. Most matchups are an autowin, but blue is the only difficult match-up. Thats why the board is built with only blue hate. If I found my meta shifting towards stax and stompy decks, I would add Ingot Chewers and Shattering Sprees likely replacing RED and Pyroblast.
This deck preys on an unsuspecting meta. When people don't know how to play against it, it's nearly impossible for you to lose. I play this deck because it's fun and because it's still low on the radar. Once this deck is seen as a big threat, its value will plummet. It will still be good, but it wont be nearly as potent as I have experienced it. I don't think it has much value at high level tournaments with 9+ rounds, but I'll be playing it at a GP this summer hoping to prove myself wrong.
