i think there should be a healing spell along with pixie that all schools learn from a quest, my idea was...
Last Resort~ Rank-X Description: Gain 100 health for each pip(changing of healing optional so it not as good as dryad) accuracy: 75-85 this way it isnt as good as dryad but gives wizards less chance of death, also i think you should be able to choose when to use a blade, such as balance blade, this way it seems more fair for balance students, such as when you are waiting for a card you want you can still use the blade late, as well for traps and wards(against enemies not pvp!)
