You dont understand it either. The reason of banning Greninja is too op is nonsense, a 5 yo kid could find out a better reason. There are mons that can check it/counter it, Specially if its locked to a move due to specs. If you abuse it currently and you keep winning, why do you want to ban it? Its not that op. Just check a storm drain poke like Gastrodon, laughs at it. Gave me a whole book? It was nice, I understood it very well, but none of them makes sense since its not impossible to kill. Protean Greninja is far harder to kill, since while you can kill Ash-Greninja with a Mach Punch, until using Shadow Sneak with Protean Greninja, makes it far harder to kill. But thats just my point and be my guest to continue this without any offense.
