Ice player here. I agree with zane actually. Scizor is free win vs Ice. Someone with decent GXE will weaken your checks before Scizor can sweep. U-turn vs Walrein and now Walrein can't check him again. Add in SR and things are a nightmare (good bug users will win the pressure war, I play bug as well). It's Scizor then Volcarona then Genesect. Only thing is Volcarona *can* be revenge killed by scarf Phys Kyu-B or scarf Mamo while the bug/steel pokes have great typing against anything Ice has.With your ice comment, at least scizor can be checked, specs lapras ans walrein do kill it. Genesect however outspeeds every mon thanks to scarf, so it's very very difficult to keep in check. As for Heracross, Avalugg can revenge kill it so long as you save it and keep it'd health up. So ice users do have a right to say genesect crushes ice. Period.
I've acquired the reqs now using basically just Ice and Bug. For my bug team I didn't use Genesect and it was fine tbh. I honestly don't know what's the point of having Genesect in this meta. It doesn't "help" Bug as a type, Bug doesn't need a lot of help imo. I've beaten Flying with Genesectless Bug plenty of times, it's just harder which should be given the matchup disadvantage. IMO you could ban Gene and Bug would still do well. Banning Pinsir for the sake of "nerfing" Bug is ridiculous seriously.
Bug is currently popular because it has great, straight forward mons that cover most of their weaknesses offensively (which is the preferred style on PS just by pace alone, like people prefer running HO than balance or stall probably cuz matches take less time, who knows):
- Scizor decimates Ice, Steel and to a lesser extent Rock (which should have an advantage versus Bug)
- Heracross can sweep Normal with Moxie Scarf if played right, helps adding pressure versus Steel, rk Fire mons, against Dark can either clean once Sableye is gone OR can break him with a Guts Band set.
- Mega Hera destroy balanced teams, mostly Water and Normal from my experience
- Mega Pinsir rapes Grass, Fighting by itself and plays a huge role on the mirror (otherwise Scarf Hera can sweep)
- Galvantula is usually MVP versus Water and it's very useful versus Flying (again a supposedly negative matchup)
- Genesect can be tuned to beat Flying, Ground, Water, Bug, Ice, Grass. This one should be obvious
- Offensive Scolipede can sweep Fire and Psychic
This is without mentioning good support like access to all hazards available (including viable users for Sticky Web), access to Rapid Spin (a must) and Baton Pass Scolipede into Mega Hera or Volcarona (Iron Defense) among others.
If you know what you are doing you are essentially reverting matchup advantages to your favor based on one of your mons. I wouldn't say Bug is the best type but its learning curve for someone decent is super friendly.
For the people still trying to argue that Pinsir creates autowins, is not that the mon is broken. This gen Flying as an attack type is ridiculously strong. Most people don't run Rock (cuz it sucks) and Steel is easy to cover.
