Build a deck of AI-made cards and battle a commander or a friend
The Card Arena is a card battler where the cards, the art and the play-by-play all come from AI. Start in the Card Builder: describe a card concept and the AI produces its art, abilities and stats. Build as many as you like, then open the Deck Builder to assemble your collection into a battle-ready deck, balancing the mana curve and the synergies between cards.
Battles are judged and narrated by AI. Play against an AI commander, describe how you use each card, and the AI narrates every clash and decides how it resolves. Prefer a human opponent? Challenge a friend with a shareable battle link and play a real-time match with the same AI narration and dramatic events in the middle of it.
Games in progress are saved so you can resume a battle later, and a match history keeps your wins, losses and draws with the turn count for each. The Card Arena is in alpha and under active development, so expect rough edges while it grows. It is part of the AI Games and Friends collection on Reality Fabricator.

Frequently asked questions
Do I need to design my own cards?
You describe them and the AI does the rest. The Card Builder generates the art, abilities and stats from your concept, so a full deck of original cards takes minutes rather than hours.
Can I play against a friend?
Yes. Play vs Player creates a shareable battle link. Your friend opens it and you play a real-time match, with AI narration and dramatic events during the game.
How is a battle decided?
The AI judges it. You describe how you use each card on your turn, and the AI narrates the clash and resolves what happens, in both AI matches and player matches.
Can I stop a game and come back later?
Yes. Battles in progress appear under Saved Battles with the turn number and environment, and you can resume them. Finished games are listed in your match history.
Is the Card Arena finished?
No. It is marked alpha and is under active development, so some things may break while features are added. Saved battles and match history already work, so progress is kept.
