Can you list the names of the formats and what they allow? We are both new at this. Thanks
There are three primary formats used for typical play:
Modified: The main format for official tournament play. It "rotates" every year after the World Championships to remove the 3-5 oldest sets so as to keep play fresh. The current modified format includes all sets from from Boundaries Crossed-On, as well as BW Black Star Promos 51-on, and all XY Black Star Promos. All other cards are illegal.
Extended: An alternative format also used for some tournaments, which allows, in addition to the sets legal in the Modified format, all sets from Black and White-On.
Unlimited: A format used almost exclusively for fun/casual play, which allows all cards that have ever been tournament legal (essentially only excluding jumbos and certain unplayable promo cards). Almost all leagues permit this format for casual play, but you must inform your opponent that you are playing out-of-format cards before a match to avoid conflict.
Besides those 3, there are some alternate formats that are more seldom used. There is the general class of Restricted formats, which are used for pre-release tournaments, and only allow cards pulled from packs distributed at the beginning of the tournament. Lastly, there is the Palace format, which includes all sets from Diamond and Pearl-On but places certain restrictions on the number of powerful cards allowed in a deck, which is based on a star system that you can research if you are interested.
Generally, if you're getting into the game, feel free to bring whatever cards you have to leagues and play unlimitted with those who agree to it, but you are encouraged to gradually change your deck (or build an entirely new deck) to satisfy the restrictions of the current Modified format.
Just remember to have fun!
