Considering werewolves are literally bloodthirsty monsters, I'm pretty sure the Selesnyans would have the same feelings about it as they would the absolutely most brutal and savage gruul.
And yeah, no extent of end to how inappropriate this character is for this section of the forum. I don't mean to sound mean or anything, but what you want to do with the characters is integrally different than how we're going to assess them. We're looking at how they fit and what stories can be told, but a lot of your concepts are sort of founded on how you can bend things around to make things novel. Which means a lot of your concepts are also running contrary to themselves since you want to make things that are mostly just different for the sake of being different.
This character has three core concepts that you're trying to wedge together, and none of them flow from one to another. Culiomancy implies a certain fascination with cooking, which would be interesting enough to carry a character itself. Lycanthropy has nothing to do with it and really really confuses the personality of the character since you want to make the character a beast half the time and... there doesn't appear to be any conflict about that with what she is. Then there's the preoccupation with elves which is... irrelevant to either other parts of the character.
One of the primary problems with your characters is that you take all these details and try to fit them together like a puzzle, but a character isn't a puzzle. It's a picture, and the elements to make it a good composition have to add up.
Most of the activities you want her to go through clash with each other. They are motivations that don't seem to belong to the same person and that's a big red flag. There has to be consistency and people can't balance such wildly different aspects of their life if they are presented as being as important to them as you present these.
If all that sounded harsh, it's a bit too bad, but softer criticism hasn't really seemed to work in the past.
I don't really have anything to say about its placement on the forum, perhaps there is a better placement for the thread, if so please let me know so I don't make a similar mistake in the future.
I'm not sure what you mean about the flowing from one to another. I'm aware a lot of MtG characters of late are really rooted in some obvious thing about their mechanical and philosophical color-coding, with a few degrees of uniqueness (sort of-- like Chandra for example) I've given her 2 interests/passions with 2 sets of 'abilities' only 1 of which is offensive/defensive (well, haven't really thought too deep about summoning, but perhaps) 2 things that are a constant part of her life (minus planeswalking) and 1 that was a silly thing she pondered about as a child that later pops up later in life and only on planes they are commonly found on (but in no way Sarkhan Troll level)
while I can see a disconnect between these things, but for somewhat believable characters, it's natural, especially for characters you might identify as "Red" characters. She has a practical everyday skill, 2 unusual traits that give her something to change who she is (lycanthropy = temporary ignorance to social norms and release of stress and anxiety, planeswalker spark = unbound from the "way things are" in one isolated area of existence, freedom to explore her curiosity and imagination and meet different people of different mindsets) and the interest in elves is just one thing for her to latch to to open her mind to how different other worlds are to her own before moving onto simpler things like "Ohh, different animals and plants mean different meal options, etc". I basically want her to have Blue's curiosity but not be Blue, just be "
Wow! Cool! I wonder... never mind, it's so more fantastic if I don't poke and prod andON TO THE NEXT THING!I'd forgotten to give any indication that the Selesnyan werewolf thing is planned to come after being able to at least quell the intensity of the influence her wolf form has on her own actions with the help of a boon of Pharika's (likely not from Pharika herself, only pointed in the right direction by her followers, considering Pharika hides stuff like that in all manner of creature) and for all I know, Gruul may be alluring to her inner wolf (apparently at least Innistrad's werewolves do feel a repressed wildness trying to get out even in human form) initially before she gains any semblance of control back, but ultimately I don't expect it to be a permanent fix.
The only relevance I see from her own PoV for her time on a given plane is
Innistrad: I was born here and up until recently I thought it was the whole world
Shadowmoor: Couldn't help it then I was a primal monster for a while.
Tarkir: Still new to this world-jumping thing, was hunted like I was some big animal--oh yeah. Then what?
Ravnica: Okay, this place is a LOT less like my home, but there's a couple of groups that like to riot, is that good?
Ravnica Continued: There's also what seems like a laid-back group with a lot of elves, I think they're cool too.
Theros: So, monsters I'm used to. More than one divine? That's new. Maybe this one can help me stop wolfing out.
Theros Continued: It wasn't easy, but I did what I was told I needed, maybe things won't be so bad now.
Mirrodin can go pretty much anywhere after Shadowmoor or Tarkir. It IS a toss up. Either she IS capable of transforming, and external mana from one of the so-called moons could still affect her transformation strangely, OR they can't be considered moons for the sake of lycanthropy and she is fur-and-fang-free. In addition, I would not intend her to arrive on Mirrodin at such a time that the Phyrexian-Mirran feud has reached a focal point.
For the elf thing specifically,
