Thank you for replying.
1) Atotomize makes my klinklang much faster and able to outspeed many mons. I get by Minior withouy taking any damage and higher speed, so I don't see why not to.
2) When golisopod is damaged by the hurricane from my oricorio, klinklang can take out golisopod, as it outspeeds it.
3) Yes, chandelure is weak to ground moves, so i figured Nidoqueen would get off some decent damage with an Earth Power.
4 and 5) Alll of my pokemon have items. And I think I can't level them past 50, I have multiple common candys too.
Klinklang - Metronome - lvl 49
Delphox - Charcoal - lvl 49
Greninja - Mystic Water - lvl 48
Sawsbuck - Black Belt - lvl 47
Oricorio - no item - lvl 49
Nidoqueen - Focus sash - lvl 48
Once again, thank you for responding, I never thought somone would :)
