The Freeze Card is one of the msot powerful and the most dangerous cards of all. (I know I've said this before . . .and it's true this time too) It has the ability to change the atmosphere temprature so it drops below zero, then it moves in and freezes whatever it pleases in a strong incasement of ice. It resembles a large whale, (and I mean large!) with a red jewel on it's head.
In Episode 33, it attacked the rink, causing everyone in Sakura's class to become incased in ice, except for herself and Li. After a long battle, Li forced the card to give chase to him, while Sakura prepared to, and sealed it into it's card form. When summoned as a card, it will freeze whatever the summoner commands it to.
