Play online, practice against AI, open a private room, or create a 3-4 player Battle Royale table.
Use Quick Play to be matched with another waiting pilot, or open a private room and share the code with a friend.
Open a table for 3-4 players, share the code, and play on one shared board.
Play the AI anytime. It runs real starter and meta decks, so it's a good way to test a new build.
Pick your favorite card art in the Deck Builder and that's what you'll see in the match.
Tournament-style matches: first to 2 wins. Build a 10-card side deck in the Deck Builder and swap cards between games. Pick "Best of 3" in Quick Play or when creating a Custom Room.
Real screenshots from real matches: the board, card details, the log, and AI games.
Paste a decklist into the box above, or open the Deck Builder to create and save a supported deck.
Quick Play for a random opponent, a private room to play with a friend, Battle Royale for 3-4 players, or a solo match against the AI. Online modes can also be played as a Best of 3 with side-deck swaps between games.
The game runs each phase, effect and combat step for you in real time. Make your plays and take the win.
