Studious is not a stackable keyword; a player winning the faceoff with multiple Studious characters will only gain 1 action token regardless of how many Studious characters were involved in the faceoff.
This card’s activated ability does not count as a Main Phase move action (which is when a player pays 2 action tokens to move one of their characters during their Main Phase). (506.4)
