The rules for Challengers say:
And it says elsewhere that whenever a card is discarded, whether during drafting or deck clean-up, it's put into this compartment. My question is how does the BGA adaptation handle this? Does the compartment have a definitive size? Or are the discarded cards only reshuffled when a player attempts to take from an empty deck? Or perhaps these rules are ignored and discarded cards are immediately shuffled back into the deck?When no additional card fits in the compartment, shuffle all cards in it and place them at the bottom of the corresponding Level Pile.
