Left overs

So, I am just now starting to get into the game of Magic. I have a fiery deck that was made from 2 starter decks, and a human deck. I know that one might need a lot of work, but now I'm stuck with a bunch of white cards. I was thinking about making a white deck, but I also like the idea of making an angel deck, with a demon deck following it. Any help, suggestions or ideas?

you should think about making a white Exalted deck. its a card ability that lets an attacking creature gain +1/0 when its the only attacker. so say that you have a 1/2 exalter and like 5 other exalters- if the 1/2 creature is the only attacker, it'll gain +6/0 for its attack. meaning you can leave the other guys for defending.

Hmmm....seems interesting.I'm not sure how many cards I have to do that though. Most of my white cards came from a human deck
