Really powerful. I suggest only one change, the mana gain. When she transforms, her abilities change but why not her mana? She’s stronger so shouldn’t her mana gains be as well? Heck even +1 to everything that’s not red/green would be better then nothing at all or +1 to red/green making it +4 when she’s transformed or something but no gain at all to the mana?
Or…even as a kind of nerf because of her being so powerful and having literally 3 more abilities then all the PWs have her mana be cut in half or something when transformed or something like “when she’s transformed she gets NO mana gain” as it could be argued as a werewolf she would be focusing on her fighting. Her abilities as a walker instead of her magic her ability to summon allies and such.
Or even give her more flexibility for those that don’t want to do anything with werewolves where her human side has her summoning the wolf tokens and the wolf side has her fetching the next werewolf instead and have the human ult be +4/4 to each creature you control and she transforms and her wolf ult not change.
why?
The only change needed without making her topsy turvy is to include wolves in her powers (see avacyn’s’post)
I understand the ideas, but they would make an unplayable PW IMHO
Her card pool of red and green means she would always be playable no matter what her mana gains are.
Either you over power her, and she’ll’get the nerf bat asap (option 1) or locking her out completely makes her unplayable after transform. No please even with red and green cards she isn’t’kiora 
lets just enjoy her first and then after some play decide if she need a small tweak…
