Place a clockwork knight on an empty square on your home rank. It fights like the real thing, then winds down and leaves the board after 6 of your turns.
You draft Wind-Up Knight in either mode. Activated: you choose when to use it, and using it is your move for that turn.
As a item card, it is a one-use consumable, drafted in either mode.
“Fully articulated. Batteries never included.”
