PokeChamp said:Yes, you can. You can play any card from any set as long as it has been reprinted in a current set. In most cases, you would need an official card-dex translation if you play an older card, such as Base set Charizard (reprinted in Stormfront). However, seeing as basic Energy haven't changed in... well, since the beginning of the game, you can play Basic Energy cards from any set without fear of penalty.

PokeChamp said:You can pull them from Diamond & Pearl, but the cards in there suck so bad it really isn't worth it.
