User blog:Kevo411/Best Nen Ability for Heaven's Arena?

Okay, I know you can't really assign a "Best" Nen ability, so I'll make it a little simpler. Imagine everyone had the same proficiency in Nen. Meaning that with a good ability and a little luck, a character could beat even Meruem. Basically my question is "Which Nen ability would be the most effective if everyone had equal amounts of aura?" If you need more clarification, I'd be happy to provide it, just ask.
