I thought the best place to look for pull ratios would be youtube. maybe find someone who got an HGSS box and videotaped it. I could not find one. I think the best way to predict what the ratio will be is to look to the old EX sets and find that pack ratio. Since Great pokemon appear to have similar mechanics to EX pokemon then it would be safe to imply they would have the same pack ratio as EXs. I just hope it is not some rediclous number like 2-3 or even 3-4 because to even try and make a good deck you would have to pay a sick amount of money to get the 2,3,4 Great Pokemon you need to build a deck. If it is like that then I will never play this game again. Nothing says screw the players like making all the good cards only avaliable to the rich and the staff.
