Void list? So be it. I compiled a universal void list that comprises every aspect from each void list available and combined into single list that is very similar to the same guidelines that the jinchuuriki use on the forum.
-Izanami
-Swift Release
-Claims of immunity to Ototon and Liquefying Super Senjutsu Ototon.
-Anything that does not have a reasonable explanation within the Naruto/SL lore
-Non Zetsu Mayfly
-Any of the recent Rikudo powered abilities
-Body Revival Technique (when used to survive the Hachimon Tonkō no Jin)
-Claiming to use an "undodgable/unavoidable/unblockable" attack
-Any custom technique that has no prescribed flaw (auto-hitting/character control)
-Kotoamatsukami
-If you have Kamui with other MS Jutsu (Such as Amaterasu or Tsukiyomi). It's either Kamui/Susano'o or Tsukiyomi/Amaterasu/Susano'o. Pick one set of techniques or the other.
I would like to add banning using Izanagi to circumvent the negative effects of Eight Gates Release Formation, the idea of it is already OP enough as it is and besides anyone can do it. The easiest way to do this legitimately is to go Seventh Gate and use Izanagi at some point while in that state. As soon as you activate it, go Eight Gate Release Formation and the match will be entirely set in your favor for that duration that Izanagi is active. Now this is all a very overpowered strategy that I thought up in as little as five minutes, the concept is sketchy but everything should doable; this is if they go by the steps above. So I would like to cut out the middle man here and just add it to the list above, which I hope no one has any quarrel over.
If anyone would to add any input or suggest something to add to the list, go ahead and fling out those suggestions my way.
