Really cool game.
With the new decks, now I can upgrade cards that are not in my deck and cards higher then 6 I cant upgrade. (Masters deck doesnt have 1 or 2) In the cursed card upgrade the higher cards are there but again the low cards i dont have... and all the cards are shown in weird order on that screen.
Also noticed on Master deck run: Tile says Destroy up to 3 cards but I am only allowed to destroy 2 cards.
