I think Sorcerous Spyglass should be legal. If my opponent's can drop a turn 3 Nissa, Who Shakes the World every game, I should be able to play an answer to it. At least make them run some artifact removal. I don't understand the philosophy of letting degenerate strategies go in Brawl, and then banning answers to those strategies. Planeswalkers in particular need more cheap answers available.
