So I recently lost a couple cards 
I have a couple spares but a few I only have 1 left. I have everything in a binder so I really have no idea where they could have gone. Anyways this got me thinking, why is there no app out there that let's you input your expansions and then spits out how many of each card you should have? I know about the squad building sites online but these don't give you an inventory of your cards. Does anyone know of a site or an app that allows this to be done?
