Does anyone know of a database where you can manage your card collection?
https://dtdb.co/ lets you build decks and select which expansions you own, so you don't accidentally build something with cards you don't own yet (expansions available via https://www.peginc.com/product-category/doomtown-reloaded/ and other stockists!). Not sure if this is quite what you're after?
I was looking for a download that would let me track my collection of cards. but thanks for the reply
