I've already had issues, when meeting up with mates to play games, of getting to the end and then going.... "Er.. Is this my Marksman card or yours"...
So I made up this little spreadsheet, you put in what packs you have and it works out how many of each card and ship you should have, (also gives totals, so you can go.. I have 65 upgrade cards).

(If someone that has Wave 3 can check the totals for the cards are right)
