Well, what are your guys thoughts on them? The three things that I had been working with were the Lance Formation (which, like Tobogan has mentioned is about bringing more guys in to attack), their vows (which would give them a benefit at the start of the game and on- I hadn't considered how to incorporate that), and questing, which I thought would be a fairly constant theme throughout the Bretonnian cards. Bonuses for quests being in play, bonuses for being ON a quest, the ability to attack and defend while questing, things like that.
I have not done too too much on this front, but I'd love to hear what else you guys are thinking of, regarding the Brets.
No reason there can't be a fan 'Deluxe Expansion', ya know
