Commander’s Choice returns in the Proving Ground event

Proving Ground is a limited-time event available from Rank 5. In the “Commander’s Choice” mode, both you and your opponent build decks by picking from the same 3 options. Legendary Fighters — Cyber Ninja, Shaman, Cosplayer — and the Hero Nun Vera are available during battles and can be earned as rewards usable in all game modes. You’ll find the event under the “Events” tab. Good luck!
