There are 108 of the larger cards and 130 of the smaller cards. The dimensions of the large cards are 63mm x 88mm, and the dimensions of the smaller cards are 44mm x 67mm. If you happened to be going with Mayday sleeves I had previously written down that I think you would want mini euro's for the smaller cards and the green pack (for 63.5mm x 88mm size cards) for the larger cards.
Kickstarter copy arrived last Wednesday and we played a couple turns then. I love the historical artwork which is what made me buy it in the first place. The dice may be a bit too random as a first impression but we're hoping it will only be a problem in extreme cases where one side gets lucky and hits most of their rolls while the other side fails.
