also, you need to decide on your approach to building decks - are you going to start proxying copies of staples once you have four?  Definitely sounds appealing to pursue a karakas(e.g.) vs _another_ four copies of path to exile...  I guess avoid proxies when you can.  Rather than proxy a bunch of shocks and fetches, try building the budget land version of this (which does look appealing, even if not quite tourney level)
