There once was a legendary grappler named Baki, he was able to envision his opponent's strengths and weaknesses in order to form a shadow boxing opponent so real that even people watching him could see both him and his shadowboxing opponent.

That said, shadowboxing with a tulpa is a very real thing, it helps to build your form as well as imagine where and how your opponent would stand. This is true to any sport, really doing it with your tulpa can help you envision and see what you're doing.
