Eleven elemental zones across three acts. Clear an act to unlock the next, then face the Convergence. Choose a zone to see its challengers.
A no-stakes spar against a bot. Pick any cards — nothing affects your collection.
You and an opponent field a hand of brokébois and battle them one at a time. Win a battle to capture both cards into your spoils zone. Capture opponent cards to add them to your collection.
The Elemental Wheel. Each element beats the one it points to and loses to the one before it. Unconnected types have no matchup.
Battle resolution. First check the wheel — if one card is weak to the other, it loses automatically, regardless of level (yes, even a Legendary). If there's no matchup, the higher Level wins (I < 1.5 < II < III < L). If levels tie too, each side draws a random card from the opponent's hand and those fight — the winner takes all four. A tie on the very last battle splits the cards.
Campaign. Start with 10 random brokébois. Climb the opponent ladder, capturing cards to grow your collection toward all 139. Beating an opponent for the first time unlocks the next and earns a bonus card. Your collection is never lost — you only gain.
