what i mean by this is it would be a better card game if you didn't just try to lvl up to get your next spell cause then everybody in your element has the same spells. what would be nice is if it was a moderate drop from enemy's a spell that can't be learned in schools so everyone has unique cards in there deck. they would still have lvl requirements on them though but then there is more customization to the game becuase you could have 100's of cards to choose from just like real card games in real life. who agrees?!? (I know this would take along time to do, but it would improve the game a huge amount)
Treasure Cards.. eventually you will have 20+ spots for treasure cards.. you could just make a deck and only use your Treasure Cards.. xpensive me knows but it would be a unique twist....
