An ice dragon sweeps a chosen rank: every enemy piece on it (king excluded) is frozen for 2 turns, and its empty squares become ice walls your opponent cannot enter for their next 2 turns.
You draft Frost Wyrm 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.
“It exhales, and the whole latitude files a complaint.”
