When an expose marker is removed (eg by an AI card) do you return it to the unused pile or discard it as if it had been consumed?
If discarded, do you reveal what the token was ?
If revealed, do you ignore the Battle Cumulation effect if it is that particular marker?
Whenever you have to remove or discard an expose marker, you put it back into the unused pile, not revealing it.
Instructions on the cards specifically tells you if you have to reveal the markers, like the Unstable trait card.
