This game desperately needs an auto save/hard save and same screen multiplayer mode. I would love to play this with someone, not just their deck and a computer playing for them. Don't really play locally, but same screen? I would love that. This game is just too cool not to have that.
Perhaps even a way to swap a card or two. Crafting is a bit much when drops aren't coming and you get spammed with same cards. You can farm and all, but you definitely need to make your card chest way big, as some cards need 5 or more cards to make just one card.
