New Cards, New Cards Alert!

I have been trying to find out what cards will sell the best!  Why?  Because I want to eventually grow my shop so it brings in more income!  If you could if you are following let me know what you think, that would be helpful!

So final question, what would look for in a card shop?  Please share your opinions because it counts.

Here are a couple of the new cards.

Your opinion is greatly appreciated!
