Extend Bio, remove some moves and replace them. I think just Wish if you want to go healer type could maybe work.

For moves... I could sudgest this:

Helping Hand
Swift
Wish
And another move...
Maybe one of these:
Echoed Voice, Shadowball, Hidden Power

This way you would have moves that could be better, or add a uniqueness and look for a different typing move, like I did with my other caracter (Who can use a steel type move)

Also, instead of going for shiny, you could make it that she looks like she has whitish fur, but still have brown around some main parts like the legs and such.

Just some sudgestions.

Edit: Oh and... wish is kinda... chain breeding usually. So that is kinda something already big. Kinda why Lugia is on the fence with that one, as well as Hyper voice being a move that is tutored.
