Pokemon Detective Pikachu in Pokemon(48)

Are trading cards for collecting or for game playing?

Both! When a trading card set is complete, most can be used to play games related to the topic or theme of the card. The goal is to collect the entire set, which can be as many as 60 cards or more. Instructions for playing are included with some cards or with the board game if one is required.

Are there any trading cards I shouldn't trade?

For game playing and collecting, any card that is a rare, super rare, or secret rare shouldn't be traded. They are typically the most valuable cards in the set. Check online to find out what cards fall into these categories.

Should I keep my trading cards in plastic sleeves?

If you aren't using trading cards for game playing and hope they increase in value, you should keep them in plastic sleeves or a storage case. Game playing cards collect the oil from fingers, so they don't gain in value as much as those kept away from hands, dust, and sunlight.
