Transformations/Stages are allowed, for example Ruin Dust or Emotionless Ink

Alternate versions are allowed, like Fellswap and GG!Fell

No prejudice is held, it’s a fight to the death.

If someone will lose a fight but can’t die, i.e Nightmare only killable from positivity, it also counts. They need to be able to win without just pure immortality.

No DT/Save hacks

Duos/Trios/Groups are allowed in reason (I.e BTT)

Nothing completely unheard of, like a AU nobody would know

I reserve the right to not allow a suggestion that obviously cannot win or is a joke.

No repeats.
