Forum:Night Asailant / Collosal fighter effect

So, I have been told that collosal fighter can bring itself back when it dies in battle, so I was wondering, can Night assailant bring itself back too?

Or were they cheating by bringing back their fighter? That may be the case, because in a type 1 game, they went to play raigeki, but when I countered with antiraigeki, they said that they were using it as a discard for their tribe infecting virus, which I doubt because they had monsters that were the same type as mine, and they could have gamed me by using raigeki.
