Ok, so I just put my first deck on the site, added all the cards to my inventory, then added them all to my deck. It's been good so far but I'm curious as to why the deck cost shows up as $10 more in the inventory list than it does in the deck...

Anybody have any idea's?

Differences in the version of the cards. Decks (currently) don't allow you to specify which version of the card you're using, so it just defaults to the most recent version, which is often different than older versions in price.

Ah, that makes sense. Thanks!
