Field notes
The import flow checks deck size and Forge support, while leaving Commander legality for the user to confirm. The site separates batch simulations, where AI plays every seat and results can be compared, from hosted Play mode, where the user pilots their own deck. Card collection features include assigning owned copies across decks and exporting a list of missing cards.
