What would be some good teammates to complement Defog Mega Scizor on a rain team? I'm struggling a bit to try to come up with something.
If running MZor on Rain you'll Need to Change quite a lot of Things to make up for what you lose:
a) You lose MPert as your physical Rain abuser, next to Kingdra/Ash Gren as your Special one. A replacement would be Kabutops, I'd suggest Z-Stone Edge
b) You lose both a Stealth Rocker (MPert) and a Spiker (Ferro). Replacements would be running Ash Gren as your Special rain Abuser with the Specs + Spikes set, and maybe adding Clef as your rocker if you can fit it in, to still have a mon that can set up rocks vs Stall like MPert could.
c) Running Defog on MZor frees up a moveslot on Pelipper for Hurricane or another Utility move. Another Option would be going Specs + Knock Off to handle Chansey
d) You lose your way of dealing with fat Waters and fat Grass. MZor somewhat makes up for the fat grass part, but you definitely Need a way to handle Things like Toxapex, Mantine, etc.
