Didn't Scott Limoges already do this for Waterbury with 4 TFK over Phids and a Tinker/Colossus as a secondary win?
It doesn't really matter if anyone has already done it, I just think its a good idea for right now and no one seems to be discussing it. I haven't seen anyone siding Orchards vs Oath yet though...
Also, @Negator, I board out 4 Phid and 4 Island for 4 Orchard and 4 Seal of Cleansing. I have not been boarding in Seals vs those decks, although I have been boarding in Seals w/o Orchards vs Belcher and other assorted combo.
