Put around 10 0's in the back of your deck, attacking sleights in the front and around 10 cure cards of which 4 are 2-4 the rest 7+. Use Curaga and dont waste the high leveled Cures.Use Beast Often. You dont need any summons. 2 beasts and one donald at times causes major damage and if lucky, some healing. Put your heartless cards to good use you may want Oogie and some other.And recharge as soon as your low on cards. Though you need high CP for deck, it works like a charm. Also, break alot and attack the flames she breathes before aiming for her, Beast CAN take out the flames for you since he damages almost everything on the field. Hope this helps. :3
