Sandbox tournament
Sealed Arena: a temporary card tournament
Open 10 temporary boosters, fuse your pool, and build a 5 to 10 fighter deck to face seven opponents.
A pool for every participant
Arena cards are temporary and balanced. Everyone builds from their own ten-booster pool.
Fuse, then build
Upgrade compatible cards, save your deck whenever you want, and submit it only when it is ready.
Eight players, one ranking
Once participants are ready, the automated tournament compares decks and awards rewards.
