As of September 1, 2007 the New Modified Format will be Holon Phantoms On. (HP-on)

It includes the following Sets, although some earlier cards may also be used if they have been reprinted in one of these sets. If you are playing a card that has had text modified in later printings, you must have either a copy of the official Card Dex or a card with the most recent printing outside your deck available as a reference for your opponent.

DeckBuilding Reminders
You cannot use cards from the World Championship decks. These are pre-packaged decks which have extremely powerful cards based on winning competitive decks. These cards are identified by a silver/grey border on the front, a signature in the lower right hand corner of the picture on the card and a unique card back. None of these cards can be in a deck in a Pokémon Organized Play event; this includes the basic Energy cards from these decks.

Cards marked “NOT TOURNAMENT LEGAL” in the lower left hand corner of the card cannot be used in Pokémon Organized Play events.

If you use any foreign language cards you must provide either an English card from outside of your deck or a copy of the Card Dex (found at http://www.go-pokemon.com/op/tournaments/card-dex.html.)

If you use any Japanese Cards in your deck the set the card came from must have been released in your country/region in order to use them. It must also have artwork that matches the artwork of the card published by PUI. If you use a mixture of Japanese Pokémon Card Game and any other Pokémon Trading Card Game cards (from anywhere outside of Japan) you must sleeve your deck completely with opaque sleeves. Note that only solid color sleeves or official Pokemon sleeves with solid colored edges are legal sleeves for sanctioned tournaments, with the exception of Prereleases.
