I confirm what NN-GroundZero said: yes, courage ability stacks up with other active bonus / ability. and yes, the only thing that can stop a Leader ability is the fact that another Leader is in the team (even if it's the same Leader).
We're very happy that everyone seems to like the new Ambre stats, now it's up to you to build some nice decks around her.
I think that if Bridget will be enhanced - it wont be much since her ability s much better than Timber's and Timber is 6/6... between 6/6 and 5/5 is quite a small space for enhancement i think
about new Leader I completely agree - one or two more with some fine abilities - maybe something like "damage cannot be decreased" or so...
about Ambre - its quite fair to be courage 3 now - assuming that you distribute pills equally you get 8*3 = 24 attack (same as Hugo) but if you try harder you can harvest up to 42 attack out of it and thats quite a lot (thats more attack than any clan except Montana could generate with their bonus) - but still 6/4 is quite worse than Hugo's 7/5 so i think theyre now equal
i think its good idea to make leaders a lot stronger than 5-level ordinary cards cos leaders feature no bonus which is quite a disadvantage in game
