Myracle probably replaces Odd Rogue as the aggressive Rogue of choice. (I think it's better than the Aggro Kingsbane or Kele/Hook Tempo decks).

Shaman is so wrecked. On the bright side, I think people will start experimenting with the dragon/elemental shudderwock decks more though. Those decks are close to having something there. Maybe it never gets over the hump, but more iteration is good.

Personally, I never liked Even Paladin as a ladder deck after the Druid nerfs. I recognize that the data says it was good. But, anecdotally, it never felt good when I played it, and I almost never lost to it. I like it even less now.

Even before the nerfs, I wasn't sure why you'd play the secret versions of Hunter over the non-secret Master's Call decks. (J/K! You play them because they high roll and you weren't a good player.) I certainly think now, you play the Midrange Master's Call deck instead of the others.

I'm not sure the equality nerf matters too much to late game Paladins. I suppose there's argument that it makes Prismatic Lens a bit worse. But it's better for Shrivallah. Some of those decks already used Shrink Ray anyway. If equality is that much worse, I can see the switch being pretty clean.

The decline of Odd Rogue and Even Paladin is a good thing for Resurrect Priest, which in turn is a good thing for Aggro Odd Mage. Which, in turn is good for the non-Secret Master's Call Hunters. All of these decks, except for the rising Aggro Odd Mage, already had a huge meta presence.

tl;dr I don't think much changes in the long run. I think Priest will be the default favorite for a few weeks. But I think that Resurrect Priest is equal parts frustrating to play because of how much RNG is involved and vulnerable to aggressive decks. And I think there are sufficient aggressive decks remaining to take advantage of it.
