Wanted to share a funny story about my nephew’s collection. He is 7 years old and loves Pokémon! I was FaceTiming with him recently and he was showing off his new cards.
He then pulls out a Charizard Lvl. X from diamond and pearl! Somehow acquired it from a family friend I think. Anyhow…I asked him to put it in a card saver, but he only had one around at the time. He had a machamp holo from champions path in it. He refused to take out the machamp for the Charizard because Machamp was stronger(200 top damage) than the Charizard.
We eventually came to a compromise and he put both the machamp and Charizard in the card saver 
. Just reminds you what collecting is all about!
