Legal Pokémon Cards - The Basics

One of my main goals was to make sure that we don't inadvertently use cards in our decks that won't be legal for tournament plat starting Sept. 1st, 2007. We did some research to figure out which sets are legal. There was not one place that had it clearly laid out to say, "These card are legal to play starting Sept. 1st". So here is what we found.

The following card sets will be legal for play in tournaments and at gyms starting Sept. 1st, 2007.

EX Holon Phantoms
EX Crystal Guardians
EX Dragon Frontiers
EX Power Keepers
Diamond and Pearl
Mysterious Treasures (Due out in Oct. 2007)
OP Series 4
OP Series 5
Black Star Promos 37 and up
Any card printed in an earlier set that was reprinted in one of these listed sets (i.e. energy cards)

Anything I'm missing?

The following list are the sets that were legal in the 2006-2007 season, that will no longer be allowed in game play starting Sept. 2007.

EX Deoxys
EX Emerald
EX Unseen Forces
EX Delta Species
EX Legend Maker
EX Trainer Kit 2
OP Series 3
OP Series 2
Black Star promos 29 to 36
