I want to know the answer to the following question:
What are a couple of styles of combat based on?
All the background I'm provided with is that "Taking the form of live events held by touring promotions, it portrays a unique style of combat based on a combination of adopted styles, which include classical wrestling, catch wrestling and various forms of martial arts, as well as an innovative style based on grappling (holds/throws), striking, and aerialism.". Is that enough to answer the question?
