One enemy knight or bishop falls asleep for your opponent's next 3 turns. It wakes early if any piece adjacent to it is captured.
You draft Sleeping Draught in Buff mode. Activated: you choose when to use it, and using it is your move for that turn.
As a tempo card, it buys time: an extra move, a skip, or a freeze.
“Tastes like chamomile and lost tempo.”
