Didn't realize that a few years ago I had bought one, forgot about it, and now I have two

I have other cards on the way but I am wondering: Is there anything I can do with just two core sets are are the cards 'lower class' and I should just mainly ignore them.

Thanks

If you start constructing your own decks, you'll probably be glad to have 2 copies of the Core Set. There are a lot of excellent, powerful and "utility" cards in the Core Set.

Thats what I needed to know.

Just gotta figure them all out...just waiting for some new cards to arrive and trying to convince my best friend and the one who got me hooked on ice and fire to try and play

The second copy of the core set is quite necessary. I also have two copies!
