Great game.
One detail, though: the deck edit and selection method (1 or 2) could try to prevent slightly heedless users like from going wrong. How many times have I built a bespoke deck in slot 2, for the purpose of a quest in particular, not wanting to modify slot 1 which I would like to stay generic, have I started a game, and have found myself having to fight with deck 1, lost and spoiled 25 energy/minutes? Countless.
