I present to you, "TooOpPlsNerf": The Movie: The Sequel: The Game: The Light Novel: The Manga: The Anime: The Anime Movie: The Live Action Anime Movie: The Cast: The RPG: The RP: The Deleted Room: The Forbidden Fruit: Your Mom: The Omega Core.
Let's start with the start of the show; Marowak-Alola. In Trick Room (and in some cases, outside of it), is a monster. Most of the meta is 1HKO, yeah. Not 1HKO, 2HKO. There a few Pokemon that can tank its stabs, but that's assuming its unboosted. This thing is a monster if you can't get rid of the +2. Now, before we get into what this thing does, let me state something.
Belly Drum ISN'T better.
A big problem with belly drum Marowak compared to sword dance Marowak, is longevity. You already hit a lot hard, why do overkill? Not to mention you can't switch out since even if you remove rocks, it's risky sending it back in. You want to be healthy, since relying on wish support while being rock weak is never fun. There are other problems, too. Haze, Heart swap, you name it. You're overall just better off with SD, though sure in some cases (maybe as a late game sweeper) belly drum could be considered better. But, I think SD works way better for the most part.
Marowak Alola can one hit almost anything. It reaches over 1k attack the minute it hits the field. It's slow, which means it LOVES TR. It's faster than a lot of pokemon in TR, including other TR abusers. Marowak Alola is the hardest Pokemon to state in on, and switch out on. A lot of struggles to beat it, but here's the problem. If your team relies on Marowak Alola, you're in a bad spot. Marowak Alola can easily be played around, though if you can't handle it properly, you'll usually have half your team down, or most of your team in range to be swept by "x" Pokemon. However, No Pokemon doesn't have its checks.
Heart Swap
Only mag and Manaphy have it, both dying to one of its attacks, but. For removing its sd boost, allowing it to forcefully switch out, or not be able to demolish your team in one hit, is always nice.
Haze Pex
For sure a counter. Comes in on the Wak, gets rids of the boost, tanks one hit, and can 2hko with scald. With provided support though, Pex is easily beaten. If Pex is done, Wak can run much more rampant.
Stealth Rocks
One of Marowak's biggest problems is being rocks weak. With provided support, this isn't a problem, however. Rocks can just beat wak if you can force it to switch enough. If you want to make sure Alola Marowak won't come out on the battlefield; just keep rocks up. Since for the most part, unless Alolan Marowak has the provided support, it can be worn down easily.
