Welcome to Koi Fish Cards

Hello and welcome to Koi Fish Cards.

This is a place for Magic: The Gathering players and collectors who are looking for second-hand cards. My name is John (ヨン). I’m a Viking from Norway, now living in Japan. I started this shop because I enjoy Magic: The Gathering and believe all cards deserve a game. If you’re wondering, the Kaldheim set probably represents me best—as a true Viking at heart.

At Koi Fish Cards, I focus on giving used cards a new home. I check each card carefully so you know what you are getting. Whether you are building a new deck, searching for a missing card, or just want to play more, I hope you find something useful here.

On this site, you will find:

  • Second-hand Magic: The Gathering singles
  • Simple guides and tips for players and collectors
  • Stories from running a second-hand business
  • Updates about the shop
  • Videos about cards, decks, and life in Japan

I hope you enjoy looking around. If you have any questions or want to share your own story, please get in touch.

Koi Fish Cards: Every card deserves a game.
