I am level 40 school of which is the best bundle for me Thank you
I'd say Prehistoric is fairly good for fire. It gives damage boosting stats and fire item cards like Fuel & Fire Dragon, it's pet is storm though, and you don't get a castle, just 3 daily rewards. But I'd still say it's a good fire bundle.
It depends what you are looking for, but I would say either Winterbane or Pagoda Gauntlet cards would be the best for any school, because they give you dungeons that will reward you at every level as you advance.
