I am so down on the Loam plan right now. Maybe it's awesome if everyone switches to Grafdigger's Cage, but I feel certain all the Snapcaster decks (i.e., the best decks in the format) will stay on Extraction. And if Loam gets Extracted, the deck won't be doing much. You have not THAT many slots devoted to the Loam package, but you are relying on it to fix your mana and to generate incremental advantage..

I really wonder if you'd be better served by replacing the Loam package and Intuitions with Tarmogoyf and something like Shackles or Threads. You aren't relying on your removal as much anymore because you can block. You have a more consistent way to generate late-game advantage. And because you can actually clock them, you have an improved matchup against combo decks.
