My grandson came over one day with Pokemon cards. I was so surprised to see that Pokemon was still circulating with the children. I remember when they first came out. It was the rage. My children were much older when they hit the market but I remember my nephew always talking about Pokemon.
The first Pokémon games, Pokémon Red and Green Versions, came to the Nintendo Game Boy system in Japan on February 27, 1996. Then the first set of cards was released on October 20, 1996, containing 102 cards, and became very popular. 
I assume the children just collect the cards and maybe exchange cards with other kids. I remember collecting cards but these cards were Beatles cards. I did not exchange these cards, I just collected and collected. Have to go up in the attic, I think that is were I last saw them…
Anyway, I don’t truly understand what each Pokemon card represents but I do know they represent something. Pikachu and Braixen Cards are special to my grandson
I also never understood the craze of Pokemon but now that they are, once again, popular with young children I want to learn what these cards are really all about.
It would be beneficial to me to learn since my grandson comes to my home holding on to these cards, very tightly I might add. He really doesn’t play with them he just holds them in his hands. So cute! 
I am not sure if I really will understand what your suppose to do with these cards or why they are once again popular. 
What I do know is the I may have missed the first Pokemon craze but I certainly am not gonna miss the resurgence of Pokemon…thanks to Christian.
