Trading is half the fun of collecting. A good trade leaves both people happy. These rules keep it that way.

For everyone

  • Trade with people you know. Friends, family and classmates are the safest. Be careful with strangers, online and offline.
  • Take your time. Nobody should rush you. "Yes, I will think about it" and "no, thank you" are always fine answers.
  • Look at the cards together. Check the condition on both sides before you agree. Scratches, bends and whitening matter.
  • Check the price on both sides. Use an approximate price as a starting point, not a final answer. Prices are estimates, and a card can be worth more to you than its price.
  • Keep it fair. If one side is clearly giving much more, say so and talk about it. A fair trade is one both people feel good about.

For kids and teens

  • Always have a parent or another trusted grown-up with you or nearby when you trade.
  • Trade in a public place such as school, a card shop or at home with family around.
  • Never share your home address, phone number, school or where you will be. You do not need to for a trade.
  • If someone makes you feel uncomfortable, asks for secrets, or pushes you to hurry, stop and tell a grown-up. You will never be in trouble for that.
  • Some trades are better to wait on. If a card is special to you, ask a parent before you trade it.

For parents and guardians

  • Know who your child trades with, and be there for trades with someone new.
  • Talk about value: a shiny card is not always worth more than a few plain ones, and the reverse. Look up prices together.
  • Remind your child that it is fine to say no, and that undoing a trade later is often not possible.

How DeckMaster helps

  • Trades are between approved friends only.
  • For younger players, a parent approves friends and trades.
  • There is no open chat for kids.
  • A fairness score compares the approximate prices of both sides. It is a guide, not a ruling, and you decide.

DeckMaster does not buy, sell or ship cards, and it never helps people meet up.
