Why is Purple/Green allowed to be such an op color combination? They just send everything to the top of the opponent's library and then cast it to gain control.
Meanwhile, Blue/Yellow can't do shit. All Yellow does is turn everything into 3/3 Beasts and play fogs without a single good wincon except Venser, Resident of Eternity.
Also the Niv-Mizzet planeswalker is fucking insane. Why does nobody play it?
