^thisI'm gonna post one of the most broken megas which should be banned, a brief analysis.
Lopunny-Mega @ Lopunnite
Ability: Scrappy
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Return
- High Jump Kick
- Ice Punch / Baton Pass
- Power-Up Punch / Fake Out / Encore
Mega-Lopunny is insane, even if looks like is outclassed by Gallade-Mega (both are broken btw). Lopunny-Mega unlike Gallade one can run an Adamant nature easily (in my opinion is the way to go) since Lopunny is already fast, access to Fake Out and is not relevant the speed lost between Jolly or Adamant; only Dugtrio and opposite Jolly Lopunny-Mega and still even using Adamant Nature you are outrunning Whimsicott max speed which is like one of the fastest mons in the tier.
Another thing that deserves be noticed on Mega-Lopunny over much other megas his his great coverage in only two moves thanks to Scrappy, Return + HJK is a perfect coverage unlike Mega-Gallade you're hitting super effective against Doublade and Spiritomb, which otherwise could be huge threats. Great coverage only with two moves means that you have a lot of room to support your Lopunny or the rest of your team.
Power-Up Punch helps to beat way easier defensive teams and along with Scrappy means that you're not walled by ghost types so you're getting +1. Baton Pass is great specially if is paired with Power-Up Punch so you can sweep with yourself and still support your temmates after all. Ice Punch is one of the best option for the last two slots on a Gligar metagame. Encore is really good since Lopunny is so fast so will work pretty well against any kind of booster, wall etc
I also wanted to add that HEALING WISH is another great option in the ice punch/bp slot to revive something weakened like a doublade or escavalier (w/e really) especially in a gligar less metagame
