They'll ban Saheeli once she's not a marquee card if it comes to that. And we can expect to never, ever get a flicker any permanent effect again.
Saffron Olive's article yesterday was spot on. The issue isn't powerful cards, it's a lack of equivalently powerful answers. 3 mana counters, 5 mana wraths, and every single removal spell having some kind of shit ass drawback isn't going to cut it anymore.
You know what would have kept Emrakul legal? Rest in Peace pre-Marvel, and Stony Silence post-Marvel. Shocking how INN-RTR, one of the best loved standards in years, had both.
Frankly, Saheeli would be less scary if Copter came off the banlist, and Copter wouldn't be scary if we had fucking Lightning Strike, nevermind Bolt. Or, again, Stony Silence.
There are a million ways to keep these decks from getting out of hand, and reasonable hate cards are part of the balance.
