and Krosan Grip.
I played 4 color up until the EPIC tourney, which has been pretty much since the Running GAGG in the beginning of the year. The mana base really never hurt me, I just cut white because it wasn't giving me enough to justify playing it. Obv with Lorwyn it will be plenty to justify in Teeg and Doran. I wouldn't worry about the 4c mana base, as all you really want is 1 mountain in play anyway, and there's not any hard color requirements besides Doran. Birds are also extremely powerful, and play Quirion Ranger, he makes 4 colors much easier.
