And with a growing collection of cards, players can build meta-defining decks, earning them a spot on the leaderboard.

Features:
- 300 powerful cards
- Playback of all automated matches
- Full automation rules to automate any strategy
- Leaderboard with rewards
- Missions that reward card packs
- Challenges that reward rare cards
