I'm going to get back into the Pokemon Card game.

well first of all, try find some cheap cards or find your old ones. you might be able to find old cards on a flea market, I managed to get my hands on some cheap cards that way.
that's the best tips I got, while I did collect the cards I ever for to play with them in my life ahaha.

 

All of my cards were fake but they were all pretty cheap I was really bad at that game though, I remember "never winning" to any of my friends when i was in elementary. Now that I see your post, maybe I should go try getting back into it as well. Kinda nostalgic i guess

 

There's an online version of the TCG on the Pokémon site. Maybe start there? Unless you don't have an account there, like it's been suggested already, I bet there are tutorials around the web, including YouTube. I was never into the game myself but I liked collecting the cards. I only have the ones from the first generation though.
