RE: Diamond and Pearl TCG: The online RPG. Game begins 3/10!
XD, nice idea. Anyways, I also thought something about PokeMarts. Maybe you could sell packs that include 5 cards if people don't want to buy singles. You know, another option. The problem is I don't know how you would randomize the cards that the packs would include. There ARE these things that you put a list on and it randomly chooses something, but it's sort of complicated. If you know of a way to do this then doing packs might not be such a bad idea.
And just to clarify, the packs wouldn't guarantee a Rare, because then there would be no luck involved. If you're guaranteed a rare, there really isn't VERY disappointing stuff you can get.
