Nature's Balance 2

I think Dr. Boom and Emperor Thaurissian are 2 of the strongest cards in the game right now, and whatever deck can make best use of them will dominate.

I suspect Savage Force druid may take the cake, but maybe some crazy combo deck pops out there.. still, the being able to use innervate with cheaper cards just seen too good.

Cheaper Malygos + nukes new meta?
