I know Stuka Joe has a series out there showing how to play card driven games solo...but, it's quite heavy (looks like a game in itself).
Anyway - I was looking at it but I wondered what was wrong with my old way - which I used for Memoir 44 - which was draw new cards each turn and shuffle. That way the opponent (you) doesn't know what you have when they are playing their cards.
It would seem that is over simplistic looking at Stuka Joe's instructions...but just wondered if there was any reason people knew of why it couldn't be that simple - as I don't often play CDGs so I'm not sure of the impact of being so simplistic?
Just throwing this out, for M44/C&C games:
Part of the strategy, and the challenge, is lining up your cards for a successful series of moves; e.g., if you have 3 or 4 cards that allow you to move in the right sector, you can act and follow through and hope your opponent cannot match your cards. Similarly, your attack often culminates (i.e., you run out of cards) with your units exposed or close to success, but you just can't draw that one last card because they are all depleted.
Reshuffling and re-drawing takes out that part of the game, as well as the increasing likelihood that you might deplete all of the "good" cards for one sector.
But they're just games, so enjoy them however you want--just throwing this out in response to your question.
