Literally just crafted 2 Town Criers and Boom, Mad Genius yesterday as well after getting bored of quest shaman. I was wondering why I was getting such garbage discovers today but I guess that answers that. Classic Blizzard move to nerf cards/ decks in a way that avoids giving dust refunds.
It's not like those cards magically became good right now. They've been great for over a year.
This is a big deal, and it's probably the nerf that was needed all along.
It's an obvious nerf to Dr. Boom, Frightened Flunky, Elysiana, and Omega Assembly, which is excellent.
But it's also a stealth buff to something like Myra Rotspring. That will almost certainly not be relevant because that card's stats are straight doodoo, but it's worth noting. The buff to power of creation is certainly relevant. Ditto for Togwaggle, although the wand is still usually the choice.
Control Warrior will still have a role as an anti-aggro deck, but I'm not sure it stays in T1 anymore.
