Start in one minute

  1. Sign in with your email. You get a code and that's it: no passwords. If you don't have an account, one is created for you.
  2. Pick your player name. It's unique: it's how others see you in games and on the leaderboard.
  3. Build your deck and play. With any Leader, or add a meta list in one tap.

Get ready for tournaments

ARENA is built for practice before a store event, a Store Championship or a regional. Use it to:

  • test a meta deck before you buy the cards;
  • drill tough matchups against the AI;
  • play a full Swiss event to get used to tournament pace.

Official events in Europe are played with English cards (French is also accepted), so check our guides before you build.
