Not sure what you're asking, but here's what I know about Modified. The first Modified was Rocket On!, meaning that the Team Rocket set was the earliest set you could use cards from. This Modified no longer exists. The current Modified I call Neon. This Modified allows cards from the Neo Genesis set and later, as well as Promo cards #21 and higher. This Modified will be replaced soon, but we don't know by what. There are two formats we think might become the new Modified. The first, which most people on this board would prefer, many call Eon. This is because the earliest set you can use is Expedition, which was the first Pokemon-E set. I'm not sure what the Promo barrier would be. The other we call Exxon. This one starts at EX: Ruby & Sapphire, and the only Promos allowed are the ones made by Nintendo.
