Challenge your opponent's last move: 50% their piece is marched back to the square it came from (if free) and stunned for 1 turn; 50% the call goes against you and your own last-moved piece is stunned for 1 turn.
You draft Manager's Challenge in Buff mode. Instant: it takes effect the moment you draft it.
As a tempo card, it buys time: an extra move, a skip, or a freeze.
“The red flag flies. The replay hood descends.”
