There are exactly two with that weakness, Skarmory and Empoleon. Skarmory is of particular note because its main strengths are in defense and setting up the battleground to favor its trainer with moves like Spikes. A good Magnezone can counteract that nicely. Empoleon is more balanced, but is also a good target for a Magnezone. Unfortunately I don't know what Jasmine's team consists of, but I would consider it very likely she has a Skarmory at least.
