Champion Concept- Magic Cat in a Wizard's Hat

The picture is a depiction of Blair, the cat from Soul Eater. I pulled this image from DeviantArt, it isn't mine.

Okay, so I don't have a lore- or even a name. I will refer to this concept as "Magic Cat". Magic Cat is currently genderless, I'm leaning more towards female- and I've name the abilities around that. (Fairy Moon would have been Silver Moon.. but maybe that's unnecessary). So Magic Cat is basically a walking, talking, spell-casting feline. Magic Cat wears a wizard's hat, and uses a magic wand. Magic Cat walks like "Puss in Boots". But, you might also be reminded of the cat from Soul Eater that was mistaken for a witch. It's good that you would think of that cat, because the Magic Cat uses "anime-like" magic styles. I even imagine Magic Cat would vocalize each ability as s/he casts them. But here's the abilities I imagine. I just want to use a spell-casting feline. Am I right??

• Magic Cat uses a wand to attack. Its Basic Attacks scale off Ability Power.
