There are a lot of good moves in this game but I think the best 2 are definite shield advantage from gemini or toxic quills from SR3.
Toxic Quill, even if spinonyx gets this move it will easily be an elite high tier
I’d say Toxic Quills, although Decel Rampage And Run followed by a swap in move can be deadly.
I think some of the best moves in the game include Constricting Rampage, Lethal Rampage And Run, Revenge Definite Rampage, Cautious Cunning Rampage, Toxic Quills, Cautious Impact, and Fabled Fangs (I might be forgetting some other moves)
I say Nullifying strike/impact/rampage/counter and swap in nullify are the best moves.
I think instant buff is good too
Cautious Cunning Rampage & Lethal Rampage and Run-
Allow us to introduce ourselves
Strike is clearly the best move in the game
