IMO Bloodreaver Gul’dan is still the most powerful hero card. Persistent life gain and damage plus a full board is well worth 10 mana and warlock has little trouble getting to that stage of the game.
Favorite? That’s a hard one.
- Jaraxxus has great voicelines.
- Galakrond, the Nightmare is in 2 of my favorite decks (Galakrond and Highlander Galakrond rogue).
- Rexxar has the most varied hero power and can be super fun with the new quest.
- Getting a random weapon and attacking with The Amazing Reno is hilarious. “Pew-pew-pew!”
- Some days you just want to hit their face with yours. Galakrond, the Unbreakable is perfect for that.
I’ll have to go with Rogue Galakrond on most days. It’s Reno when I want to meme, though that’s partly due to Mage’s ability to go full-blown RNG.
Side note: I’d love some Neutral hero cards. They would be more generic than class ones. For instance, maybe one in the mini-set which deals with honorable kills. Battlecry: trigger your honoable kills. Hero power: trigger a friendly honorable kill, your honorable kills triger twice, or something like that. It’s not a class identity and it’s perfect for the theme of Alterac Valley. Granted, it wouldn’t be useful much unless honorable kill becomes an evergreen keyword at some point.
