It's not finished yet, but any rough estimate for the Tier of the Magical Girl?

Rough list of class features:
- Costume points that grant various abilities, notably bonus weapon damage (up to 18, bonus elemental damage (up to 6D8). bonus speed (up to 60 ft), flight and Charisma (main-stat) to AC. Can't have all at once, but switch between them daily.
- Mettle and Constitution to AC
- Medium BAB, good Will&Reflex saves, 4 skillpoints/level, social skill list.
- Illuminations - supernatural effects that can be used all day, but must be resource-managed during an encounter. Notable effects: touch-attack ranged attacks with good damage. Melee attacks that prevent attacking or nauseate for several rounds. Auras that provide Mettle&Evasion, healing on melee-attacks or better saves.
