Encountered a bug: Attempting to replace a card, after pressing re-roll, leaved the game just stuck with a single glowing orb in the center of the screen. Unable to navigate away from this screen without just leaving rift mode, and attempting to re-enter the run brings me back to this screen.
As a note: This mode is more pay2win than any so far, since you can convert IRL money into gold into orbs into spirit, which is consumed on card re-rolls. Meaning, if you pay more money, you have a better chance to get a deck constructed to your liking. This is.... dangerous territory, to say the least. Given that the spirit costs seem to increase exponentially, there is eventually a limit, but still, for the long-term health of the game, I think the ability to do so is problematic. As a short-term method of milking players for dollars, it's great, though.
