Battletag: Zolgear#1470 Region: NA Trade Only?: Yes, you go first.
For reference, Naxxramas had 30 cards, Blackrock Mountain had 31, and League of Explorers & Karazhan had 45 each.
Blackrock is the closest to the 35 cards we'll be getting in the upcoming expansion. So, I would expect 2 class cards each and 13 neutral cards. Those 4 other cards I hope go to the "Explorer" classes in a way to balance out the Legendary count since the EVIL classes got Galakrond.
They could be hero cards themselves or maybe new Legendary Spells. Either way, something to level the playing field lore wise would be fun.
Is there any specific situation when you're supposed to use Nozdormu the Timeless? Do you usually just play him on turn 4 and hope your opponent doesn't have much to play or wait until you have a board clear in hand? I haven't had the chance to try a deck out with him in it, but giving your opponent the first chance to play with 10 mana doesn't seem so great.
Chameleos is considered whatever card it's currently transformed as instead of what it normally is, a 1/1 Beast Priest card.
So, when it transformed into the Neutral card Lightwarden, Vendetta correctly sees that you don't have a "another class" card in your hand anymore. Everything seems to be working as intended unless there's more to it than the screenshots show.
