Allow players to continue against AI after a human opponent concedes

I would like to suggest a feature where, when a human opponent concedes a game, MTG Arena gives the remaining player the option to continue playing against an AI opponent from the exact game state where the opponent conceded.

For example:

Opponent concedes → Match win is immediately recorded → “Continue against AI?” → Yes → AI takes control of the opponent’s existing board and hand/game state.

The original human match would still be completely finished and the win would be recorded normally. The AI continuation would simply be an optional, separate sandbox continuation and would have no effect on Ranked rating, matchmaking, rewards, statistics, or the result of the original game.

This would be particularly useful when:

• A player has assembled a complicated combo and wants to actually play it out.
• An opponent concedes immediately before the player can demonstrate what their deck is capable of.
• Someone is testing a new deck and wants to see how a particular board state develops.
• A player wants to practice sequencing or understand how their deck performs from a particular position.
• A player has spent several minutes setting up a board and would rather not have the game simply end without being able to use it.

The AI would not necessarily need to be perfect. Even the existing Sparky AI would be useful for this purpose. A stronger AI in the future would make the feature even better.

Ideally, Arena could offer two choices when an opponent concedes:

“End Game” — finish normally.

“Continue Against AI” — preserve the current game state and let the AI take over the opponent’s side.

This would not undermine competitive integrity because the human match would already have ended and the result would already have been recorded. It would simply give the winning player an optional way to continue playing with the board state they had earned.

Players have already discussed wanting this functionality in the MTG Arena community, so I believe there is genuine interest in it.

I think this could be a relatively simple value-add feature that would make Arena considerably more enjoyable, particularly for players who enjoy combo decks, experimentation and deck testing.
