Kold War Sonya in faction

I don't know about you guys but unless I have a power drainer I can't seem to beat any Sonya team variations. The two I'm seeing the most are some with Jason and some with balanced kenshi and another spec op with wrath hammer. Even without the hammer, by the time I'm done with the first one I have two opponents leftover with two bars to try to beat. I'm not saying I can't beat them, just that any time I do lose is against a Sonya team. Is anyone else having trouble against her?
