Alright, some small reviews:
The Corrupted Nest looks fun but not sure if Bearmantle's HP will make this fight too easy due to essentilly countering the boss one, I guess I'll have to wait to see both characters decks in order to find out. About the cards, I find Dark Eggs too polarising and RNG-dependant and while Cleanser is cool I'm not sure if demon tech is needed in your expansion. Still a good card, near vanilla statline silence. Dragons of Nightmares is good, nothing to say. Same about Phantom Menace, balance seems okay and it's a good removal. I like Nythendra and it must be fun to wreck it with an Enrage Warrior :P. About the cards, not sure why Onyxian Claws is rogue, it's always cool to have healadin support like champion of the dusk. About Ysera, you should make her deck full of expensive dragons because the HP only pays off if it's 4 mana or more. Verdant Drake is a good idea, I like your cards that give Dream cards. Ysera, on the other hand... It wrecks Zoo because if they have a full board they are screwed, and the card just costs 4. Honestly the effect is original but I don't like it, it could break the game by giving your opponent useless minions. And if you use her you'll most likely be prepared by the effect with Silence and such, while your opponent not.
Podling Seedspreader is good, the effect pays off with just one Treant so the statline is justified. I prefer the second broken mystic just like @McF4rtson due to the first one being useless if hero is at full health (so near always useless if played on curve). Change the statline though, too low. Both infiltrator dagger and unbrafen soulharvester are good and original, plus I love 1/3 1 cost minions (yes, I've entered hearthstone after the Tunnel Trogg nightmare, so I don't have PTSD from them). Funnily enough, while you said in the last wing that you were going to make an Ogre magi with a Spell Damage based HP, I was thinking about making an Elemental with a similar effect as your Oger Archmagi's effect. Maybe I'll still do it, I'll see. The minion is good, a better version of Ogre Magi (though I guess that's intended), but old magi was tash anyway so it shouldn't matter. Boss HP is like Kalec's one but written different, maybe you want check that out or just leave it with your own writing. Ashtongue Spy is cool and Akama interesting to destroy small minions.
Ok, so I've remade Vanessa's HP to something more interesting:
I was thinking about the best bosses of Galakrond Awakening, and Khadgar vs. Avalanchan came to my mind. I love to replay that battle from time to time just to see in how many turns I can defeat the boss and which overpowered combo I can make. So, I wanted to make Vanessa similar. That's why she'll have a deck focused in customizing your hero power. The following cards are the ones her deck will be formed with:
Hero Power explanation
You'll start with a useless hero power. When you play one of the above cards (except starting again, of course) you'll add an Enchantment to your hero power. Targetting your hero power will let you use the enchanted effects. However, there's a limit of 3 enchantments. If 4rth enchantment is added, you'll lose the oldest one (the first). Enchantments can stack, including Hakkar's cost, and if one Hakkar's blood leaves your Hp cost will reduce.
Not sure if it's easy to understand, so I would like a bit of feedback. Also, I'm not sure about the warrior common, which one of those you prefer?
The first one is more 'Piratey' and more suited for aggro, while the second one is more for control. The second card is more original but mostly useless and I'm not sure if there's enough Pirate sinergy in this set (Grim Blacksmith is pirate but not aggro) so I'm not sure which card I should post.
Also, why isn't that post on hearthpwn news?
