Your deck has to have exatctly 60 cards, and you can't have more than 4 of any one card other than basic Energy cards, in your deck (the basic energy cards are , , , , and ). A card counts as the same as another card if it has the same name--it doesn't matter what else is on the card.

To make a new deck, first notice that all the cards other than the Trainers have different Energy types on them. Your deck should probably include one or two of the basic Energy types, and you can choose to add some Colourless () Pokemon if you like. If you choose just one Energy type, you'll always have the right kind of Energy for you Pokemon, but you won't have as much variety to choose from. If you choose more than one Energy type, you'll have a variety to choose from but you'll run the risk of sometiems not drawing the right type of Energy for you Pokemon. And be sure your deck has enough Energy cards (most decks need 25 to 30).

Once you've chosen your Energy types, pick Pokemon and Trainer cards that work well together. Do you want to build up big Pokemon to crush your opponent? Then put in a lot of Evolution cards and some Trainers like Pokedex taht help you find those Evolution cards. Do you want to do a lot of damage to your opponent's Pokemon very quickly? Then pick Pokemon that don't need to be evolved and cards like Plus Power to do extra damage. Decks with a special purpose like the ones mentioned above would be great, so try to make decks with purposes and tell us the purpose.

After you've finished making your deck, test it out, battle it with other decks and improve it! Take out what you don't need and add what you need! Do what is needed to make your deck the best! Then you can battle others and see who is the Pokemon master! Put your deck on our site to see which deck is the best! We might put on a Best Deck of The Month soon...but PLEASE do not make up your deck, or else it's not fair for others and no fun for anyone because it's fake.
