I open this topic to gather the never ending one on one line up. Example:
Yukigaaru (item: painkiller) vs Tori
Yugana vs Noubou

Anybody with painkillers 1 vs 1 with Tori is never ending.

I also Find Noubuo vs Dakia 1 vs 1 never ending.

Edit: Kurai vs Kurai both with 10 hp smh

Kurai Vs Kurai
Yuukigaru vs Daiki(Both have lots of HP and are doing low dmg)
..I know more but i forgot :D

Yuuki vs Daiki is not never ending. One side eventually wins.

EDIT:

Hahen Vs Hahen each with a drain on the other. (Yes, I've been in this situation before).
Megami vs Megami.
Jatai vs Jatai (Without snake trap or Poison darts)

Me and asmasm did a 10 hour match before with both kurai's unprepped at 10 hp. o-o But finally, I won.

Wouldn't one just stun the other?

And Jinsei vs Jinsei is forever attack then heal

The To Jatais would fear each other having snake trap up, thus never attacking each other.

Hahen Vs Hahen each with a drain on the other. (Yes, I've been in this situation before).

Wouldn't the first Hahen that pulls Poisonous Sickle win?

Niwa vs Niwa can be annoying depending on the person's energy. Tori vs Tori.. and well like elamento said, Anyone with painkillers vs Tori is never ending.

He means Leeching Sickle, not Poisonous...

The question is who is the retard who had enough energy to use Poison Sickle but used Leaching when he is being Leached?

Edit: Wait Fleur is right they still gain one energy a turn... So lowest health person loses.

Yeah, lol. Roach, did you use first or second?

yuki without kunai vs jun is never ending.nobuo vs yuki

Yeah there should be a time limit on games and if it lasts that long then the battle cancels.

Yuki vs Yuki isn't endless, I have already proven that. You have to attack yuki when he uses his counter. It sounds dumb but you get it removed and then you can damage him the turn after the next. You will take 10 damage but he will take 15 and over time you will win if the hp are the same to start or close.

Yuki vs Jun isn't never ending too. Yuki can't deal damage to Jun since this will use Focus, but Jun can. He attacks while Yuki has Swip Stance, get countered and Swip Stance goes in a cooldown of 2 turns. Then Jun is stunned by Hard Right and in the next turn can deal damage... even if Yuki goes invul in this turn, this wont be possible in the next cicle.

And what's taht: niwa vs niwa when both have the Metsubishi
