I must disagree Poppy. Theorymon gave me a perfect example for Freeze Shock.
You're using a Kyurem-B against a Stall team, that has Chansey, Giratina, and Skarmory up. Fusion Bolt is resisted by Giratina, Outrage is resisted by Skarmory. The best choice for you right now is Freeze Shock - it guarantees that something is going down, without thinking much. It's a good filler move, in my opinion.
