Wing mentioned that Zushi had one-in-ten-thousand talent among nen users, and Gon and Killua were more like one-in-a-million. Given the relatively small number of Hunters, it's safe to say the vast majority of nen users aren't even good enough to pass the Hunter Exam. When Netero and everyone said it was very unlikely for "rookies" to pass the Exam, what they probably meant was "people who don't know nen".
Anyway, back years ago when the CA arc was still on hiatus, thus before Leorio's nen powers were revealed, I invented one for him based completely around his bargaining skills.
Name: Let's Make a (Nen) Deal
Classification: Manipulation
Activation: The condition for activation is either:
1) The user makes physical contact with the opponent and says "Let's Make a Deal!"
2) Asks the opponent if he would like to make a deal (this would even work over a phone) involving nen, and the opponent agrees to it.
Use: Both parties are immediately transported to an isolated nen-space that resembles a small room, which contains only a green-felted poker table and two chairs, called the "Bargaining Room". The light is dim, there is a slight haze from cigar smoke, and soft jazz plays in the background. While inside the "Bargaining Room" both parties are in zetsu state (unable to use nen) and all weapons on their person disappear. In theory, they could still fist-fight, but that isn't the point. The user must completely explain how his ability works.
In order to leave the "Bargaining Room", the user and the opponent must make a "deal", involving temporarily shutting off one or more facets of their total nen ability. While anything imaginable involving nen can be laid down as part of the "deal", some common elements would be:
1) Nen classes, such as one's use of Manipulation, Reinforcement, Emission, etc.
2) Nen abilities such as En, Shu, Gyo, etc.
3) Hatsu techniques, in whole or in part.
The "deal" may involve any number of nen elements, and they do not have to be of equal importance or even exist (example: a hatsu class you don't use) but each party must sacrifice at least one. Sealing the deal is done by both parties agreeing and then shaking hands, at which point they are transported back to normal space. The agreed-upon nen abilities will remain shut off and inaccessible for a period of 24 hours, or until one or the other is defeated (killed, knocked unconscious, or surrenders) at which point abilities automatically revert to normal for both. Note: If no agreement can be made after a period of one hour inside the "Bargaining Room", both parties are transported back but will remain in total zetsu state for 24 hours.
An example of a simple deal between Gon and Hisoka would be: Gon sacrifices Emission, Hisoka sacrifices Shu. For the duration of the battle, Gon would be unable to use the "Paper" element of his Jajanken, while Hisoka would be unable to strengthen his playing cards (or anything else, for that matter) with nen to make them sharp.
Strategy: It is very important to have information on the opponent's abilities before attempting this hatsu, so as to be able to get the most out of it. Information can be gathered and revealed simply by what each party offers or refuses. For example, if the user proposes that Kurapika sacrifice Materialization, and Kurapika flat-out refuses, it would imply that Kurapika has a Materialization ability. The user is under no condition to offer anything useful, however, as mentioned before. If Gon sacrificed Materialization, on the other hand, he would lose nothing because his hatsu doesn't use it at all.
A simple advantage can be gained by the user if he has any team-mates, by refusing to make any deals, and emerging after one hour with both he and his opponent in zetsu state, whereupon his friends would have an easy time beating the opponent. However, he must be careful, because this could backfire if the opponent also has allies.
