How do you defeat duna and her team in fossil fighters

Well the you need is a level 6 or up team. I used a level 6 Alectro, a level 6 Venator, and ether a level 6 Spinax or a level 8 Shanshan (I'm not really shure what one i used.) My tip is get Duna out first and get the her rest of her team out right after Duna.
