Yeah he obviously wants to be in a heavy creature deck. Also I'm good with most planeswalkers being playable but wanting specific sort of decks to be good. Not every planeswalker needs to be format warping.
I can't imagine that Brady would leave. It's not like they have a Steve Young or Aaron Rodgers waiting in the wings or will be able to draft an Andrew Luck type player so I doubt the Patriots would get rid of him and they've been competitive every year for the most part so doubt he'd leave on...
Turn 1 Green land > Birds of Paradise.
Turn 2 black land > Domri
Turn 3 Twilight Mire > Obliterator.
Don't even need the new fetches! The idea is cool, but doubt it would work well in practice on average.
