I just traded for a Big Furry Monster and want to try running it. Seems fun. It is certainly a lot of mana so I need some big ramp, a reasonable amount of protection while I get to 15 mana, and a way to actually find two specific cards. Not sure how well it will work but I want to try. Here is is my initial thought, would love some feedback as I've never run a deck that requires this much mana so I don't really know how it plays.
