Time to make another unnecessary long ass post.
This argument is completely flawed, let me give you another example of what you basically just said:
Code:
Player 1 sends out Keldeo
Player 2 sends out Charizard
Turn 1:
Charizard mega evolves into Mega Charizard Y!
Keldeo used Scald! It did 39-46%
Charizard used SolarBeam! It did >100%! It's super effective!
Keldeo fainted!
I've tried to effectively keep this the same. Scald is neutral after factoring in the Sun (this is assuming the SubCM Keldeo - probably its best set currently. The issue with this argument is that its very specific - why would you ever leave a Keldeo in on a Charizard if you run the risk of it being Mega Y? The same argument can be applied to Scizor and Lopunny - why would you leave Lopunny in on a Scizor to risk it having Superpower? I haven't even mentioned the fact that
@Gold 2.0 stated - Scizor, especially mega, has pretty amazing bulk, and almost all variants of Scizor run quite a lot of HP/Def investment to generally tank hits.
Your idea is on the premise that you are using Lopunny to sweep - as I've told you multiple times now, this is not what you should be using Lopunny for. It is primarily there for guaranteed revenge killing and late game sweeping. There aren't many things that can switch in AND take two hits from it in the OU tier, especially with P-u-P, so this argument seems fundamentally flawed.
Next up, you then compare it to another list of Pokemon, similarly to how you did so before. Again, like before, none of these Pokemon do what Lopunny does. Mega Sableye is a wall and support mon; Mega TTar is a tank; Mega Metagross is a setup sweeper; Mega Chomp is... well Mega Chomp, it's pretty crap however you use it.
You then go on about how Lopunny doesn't get SD, and yes you are correct, it does hurt it. However, the role Lopunny performs doesn't require it to get to +2/+4 - it just revenge kills and sweeps late game. If you're trying to sweep with it, you aren't using Lopunny correctly.
You said you've used it on one team - I've used it on many many teams, ergo I've had more experience lol.
