1. What does "Revenge Killer" mean? I have seen it been used on the site but I don´t know what it means.

I thought Phazer were Pokes with Dragon Tail, Roar & such. Isn't what you said called a Hazer??

Its fine is sort of right, seen as phazing is used not only to abuse hazards but to play witht he foe and nuffle stat changes and subs though up is more correct haze is more support.
