Exactly. Thats it. You'll only play with your brother and sister in your house. For that youre gonna buy an actual Trial Deck, playing with which, at least imo isnt even as much fun as using an actual deck. Plus you'd have to wait for shipping and pay a good amount. If you wanna play with Brother/sister at home either
1) online sims like CFA or Untap or wait for VG Zero hopefully coming in a few months
2) Color Printer. I've done this before. Either buy those RS. 10 Pokemon card packs, 1 pack has 10 cards 5 packs will be enough. Save images of Deck, go to a shop and get them printed on a sheet. Cut and paste on the Pokemon pirated cards and there you have a deck with nay card u want to play at home and it will not be expensive either.
