There will be some new creations somewhere among the fold, however, the revival of some decks will happen. Also, there were decks that were on the rise prior to the nerfs and they will continue to be a force:

1) Even Shaman. It’s a pretty board heavy deck, but it will certainly benefit and there are already results garnered from this deck.
2) Control Shudderwock Shaman. Yep, it’s pretty control/removal heavy and will be more common.
3) Quest Dragon Priest. It’s a pretty strong control deck with added value in the arch bishop and quest. Expect it to be played more.
4) Odd Rogue. I’ve been tinkering with mine and actually found spiteful smith to be a good addition.
5) Warlock Zoo. I hope this deck comes back and becomes a decent force.

Also, tech choices will remain important in decks. I would tend to lean that double silences will be lessened and maybe only 1x or none will make it into decks and that could add to the strength of some decks. Weapon removal is still important I believe, but only enough to warrant a 1x. Also, death rattle might be a surprise factor here, namely skelemancer. I’ve been running a skelemancer deck along with devilsaur egg and they work wonders vs a heavy control meta, especially on a doomsayer turn.
