Another thing that annoys me is the upped-unupped thing.
When you spin 3 of the same card, but some are upgraded, it doesn't give you the card. I think it should.
Ex.:
If you spin 2 unupped cards and one upgraded one, it should give you the unupgraded one.
If you spin 2 upgraded, 1 unupped, it should still give you the unupped card.
