Natureborn Counters
Natureborn has two different forms that could be countered in a couple of various ways. In human form, she uses ranged attacks and grants Energy to allies. In deer form, she has a higher HP and grants an attack buff to allies. Both forms, however, rely on her Super to heal allies. So, having units that can drain energy and reduce healing will be an effective strategy to keep Natureborn from supporting her team. And to accommodate both forms, try to lead attacks on both the frontline and backline.
