There are ~11.5k cards, most are common / uncommon from Zendikar (2 boxes). There is 1/2 box of M10 and 1 row of Worldwake.
You can see a spreadsheet here: https://docs.google.com/spreadsheet/ccc?key=0AkfOxwGqr0pRdHdsOXprdmtCMjQ5OFVSQ1JlWTlRVkE&usp=sharing but it is not totally accurate. For one, WWK cards are not counted, and I already ran into an issue where I thought I had a card(s) because it was listed, but didnt actually have it. The exception is that the ones with numbers under the Kingdom column have been counted and verified. Even though Card Kingdom does not want most of my cards, I can still get ~$190 selling to them. If you are interested, please post or PM an offer.
