I'd really rather they don't ban survival. It's a good card an finally has found a home in a competitive deck. It's been posting good numbers, but it's also been one of the most played decks at tournaments, and has been preying on other popular decks.

This article shows that the only other deck played more than survival is merfolk, which has a dreadful match up against survival. Only makes sense that it posts good results when the meta is either playing survival or playing decks that lose to it.
Heck, if you come up with a deck that beats both merfolk and survival with 55+% I think you'd sweep a tournament.
