It's about as predictable as a choice would get, but whatever, in my opinion it's clearly the next best step for Team 1 based on Team 2's current choices. While it's obviously a hard counter for both Sub Heatran and Scarf Keldeo, Jellicent's purpose extends much further than that. As Kyurem-B is very dependent on hazard support in order to be functioning most effectively, we'll need a solid spinblocker in order to try and keep Team 1's hazards up for as long as possible, and SDef Jellicent is perhaps the most reliable spinblocker in OU. It also has very good defensive synergy with Kyurem-B: taking the Fighting and Steel attacks frequently thrown at it, and in return Kyurem-B resists the Electric and Grass attacks aimed at Jellicent.
