Magic: The gathering cards ebay bulk?

I bought a bulk of 3000 mtg cards off ebay in three pieces of 1000 for some $46 including shipping. It says it includes ten rares for every 1000 and commons and uncommons, plus no more than five of one type of card. Am I going to get a lot of shitty rares with crap cards, or will it it all be reasonable playable etc. What can I expect, will I really get a range of commons and uncommons, or just the crappiest ones from each set?
