IV91 Scizor with FC/XS

I have both variants, steel and bug moves. Didn't bother powering them up though. They are already serviceable at 2200+ CP. (For me)

I think it is, arguably, the best counter to exeggutor. It is probably not the fastest (I think either Gengar or Flareon takes the cake) but it is the most powerful (resists all exeggutor moves plus double effective into him).

The downside is that bug moves are resisted by a lot of types. You will not be able to use it for a lot of types. However, you do have arguably the best bug type in the game (arguable with pinsir with bug bite/x scissor). If I were you I would probably power it.

It's a beast.
I'm going to be original here, its best use? Blissey prestiger.
My 2400 CP FC/XS Scizor can take out a 2800 CP Blissey with a good chunk of healt left. Especially useful against ZH Blissey.
You won't get the max prestige points but it's definitely useful.

I honestly use mine to take out eggy, any psychic defender, or even blissy surprisingly does really well especially if they have Zen had butt and psychic. He is really fun to attack with but remember he's probably limited to those the defenders

I have the same one and like others have stated, I'd confirm that it's fun to use, but in terms of winning the battle, I think Flareon is king in knocking out Eggs even without the double SE. I haven't powered mine up yet, but may after I have a surplus of dust.

XS doesn't do that much damage so after a full energy bar charge, you still need like 10 seconds to unleash all 3 while a FS/O Flaeron will charge up 1 Overheat and destroy eggs after that...

The joys of powerful 1 bar charge moves like HP or Solar Beam (or old Thunder)...knock a Vap to half health, Solar beam with eggs...dead Vap...so satisfying.

I have a Bp/Ih one, that I got on my first evo...I have tried 4 times since to get that exact moveset you have.

For me, it would be going to lvl30-31 at least.

Amazing prestiger against Exeggutor. If it's too high for prestiging, there's not really any niche use for it that another Pokemon can't do equally well if not better.

For example it could be used vs Blissey, resisting all it's moves, but there's plenty of other viable options too, that either do it faster or use less HP, or both.

Against Tyranitar there's also other options. Machamp being the first to come to mind, but even if you don't have one, I'm sure everyone has at least one Vaporeon.

It won't be the #1 optimal counter to anything besides Exeggutor, but if you don't mind that, power it up anyway. It's a cool looking Pokemon and you don't always need to use your top 6 attackers to take down a gym.
