FireEmblemGuy has said all that needs to be said, but I'd like to add something.
Alternatives to Pokemon Trading Card: Asobikata DS:
- If you wanted the set for the card collection, then the sets are the Generation 5 Green Tornado, Blue Assault, and Red Frenzy starter packs. They can be bought separately, most likely for a much cheaper price than what they go for in this set (unless you want to import the Japanese card sets. That may get pricier).
- If you wanted the set for a Trading Card DS game, then move on to Yu-Gi-Oh! or emulate Pokemon Trading Card Game 1 or 2 for the Game Boy Color. There is not much of an alternative for the Nintendo DS, and absolutely no official/legal Pokemon-based alternatives.
- If you wanted the set for just another Trading Card game of any kind, then may I suggest the already-suggested official Pokemon Trading Card Game flash game at this website?
I must also say that there's a chance that this game teaches Japan's rules instead, if the rules between Europe/North America and Japan are different. It may not teach competition rules, either. So even if you DID want this to learn how to play, it may not be the exact way for your region or competition-friendly.
