I found myself purchasing all 3 boxes of Battle Star Galactica today and was looking for a simple card count so I knew how many sleeves I needed to get. Since there wasn't a simple answer here I decided to offer assistance to those people who might later be in a similar situation.
110 Standard American Sleeves (Green Package), 128 Small American Sleeves (Yellow Package)
82 Standard (Green), 64 Small (Yellow)
110 Standard (Green), 28 Small (Yellow)
302 Standard (7 Packs of Green), 220 Small (5 Packs of Yellow)
this assumes you want to sleeve every card the games come with.
