Great way to get additional cards for your EOJ game. You can search online to see what you'll be getting in a specific Theme pack. With booster packs all you know is that you'll get 5 common cards, 2 uncommon cards and 1 rare / ultra-rare or phantom card. Be sure to download the Biolith Rebellion Set 2 extention on Playstation Network, or you won't be able to use the set 2 cards when playing the game. Too bad that there aren't any playtrade parties offering these cards as play.com only sells to people living in the UK.
Im only knocking a star off due to the slimmer chance of getting ultra-rare and phantom cards. I bought 10 of these puppies the other day and got a whole ONCE ultra-rare card.
But obviously you cant truly play hardcore unless you buy booster packs...and atleast they are relatively cheap.
I just wish play.com would sell the set 1 booster packs!!!1 COME ON!!!
