So does anyone else absolutely hate dealing with Mega Lopunny? A 4 HP/252+ Atk/252 Speed set with PuP, Last Resort, and Fake Out in that order can just trash an inordinate amount of stuff in one hit, and most of the rest goes in two, the rest rest are some very specific bulky/defense steels/rocks. To put it in context, Unaware Pyukumuku gets guaranteed 2HKO'd by the combo without rocks, and thus is forced to burn Recover PP until Lop runs out of Last Resort, and it cannot switch in except as revenge. Besides this, your options are a very specific Mega Beedrill set that very easily gets ganked by basically the rest of the meta, or Trick Room, from my playing. So you have three options, two of which are running something that will have their potential greatly reduced and one of those requires either a free turn or a sacrifice, or an entire team format that really isn't something you can just pick up and play. So really, full accessibility in this meta is gated behind learning a mechanic that takes time to master, probably more time than this meta will be around.
For a format that's getting its attention as an OMotM, it's really not a healthy influence, and annoying as fuck to fight.
