Alcremie just runs sweet Veil and ur cooked, hat’s G-max Move is super bad (probably will run Normal Dynamax) lucario should run special this gen due to steel beam, zolt can use electric move to stop the sleepI'd like to open up a discussion about a Pokemon that might be uncompetitive: Grimmsnarl.
Standard set I'll refer to is the one I've seen on ladder and in roomtours: Drain Punch / Brick Break + Play Rough + Darkest Lariat + random status move.
Grimmsnarl's main attribute is its G-Move, G-Max Snooze, which prevents sleep. In most conditions, it uses it turn one and Max Guards on turn two to prevent being 2HKOed. After a Pokemon falls asleep, Grimmsnarl spams Fairy-, Fighting-, and Dark-type moves until the opposing Pokemon dies. Now this doesn't seem like much, but Dynamax gives Grimmsnarl enough bulk to survive most attacks.
Since Grimmsnarl is common on ladder, I've found that I have to run one of a select number of ways to beat it in order to be consistent on ladder instead of running, say, two Pokemon that require three turns of sleep to beat. Many Pokemon can 2HKO or 3HKO Grimmsnarl if they get lucky with sleep turns (e.g. Cinderace), but Grimmsnarl can win if it gets good sleep turn RNG. There are three ways to counter it: Fairy-types, Electric-types, and Steel-types. Fairy-type and Electric-type Max Moves set terrain that prevents sleep. Powerful Steel-types can OHKO Grimmsnarl. Problem is, many Pokemon that fit under these categories can lose anyway.
But can't Pokemon X beat Grimmsnarl? Here I'll list supposed hard counters and explain why Grimmsnarl can beat them (not a comprehensive list):
Edit note: Non-G-Max Alcremie and Hatterene can beat Grimmsnarl. But who'd use non G-Max?
- Poison-types: Poison-type Max Moves' power are capped at 95. Not enough power.
- G-Max Alcremie: Doomed by its G-Move, which does not have the Misty Terrain effect.
- G-Max Hatterene: Same as Alcremie.
- Dragapult: Although it is a fine user of Electric-type coverage, its Fairy weakness prevents it from beating Grimmsnarl.
- Dracozolt: Similarly doomed by typing like Dragapult.
- : Has Thunder but a nasty Dark weakness.
- (Jolly): No joke, I've seen Grimmsnarl survive this mon's Meteor Mash. Similarly with Alcremie, people are forced to run Adamant now to OHKO bulky Fairies.
- Not enough raw power to OHKO Grimmsnarl. Can be finished by Fighting-type moves into a Dark move.
- Same with Ferrothorn.
- Galarian : Again, same.
- Doesn't have the raw power to beat Grimmsnarl. Beaten by Dark-type moves.
This is akin to Gen 7 Mimikyu: we've only seen the top level, the standard set, like Mimikium Z. It's too early for many players to realize that Grimmsnarl can use various sets to defeat its normal checks, such as Fire Punch and Babiri Berry for Steel-types, Stomping Tantrum for Electric-types, and special sets for physical walls. Likewise, Mimikyu had Curse sets with Ghostium Z, Rock Tomb, or even berries, and its offensive Ghostium Z and Mimikium Z sets.
The problem is that this is uncompetitive: regardless of your skill at mental games, Grimmsnarl has the potential to defeat a majority of Pokemon in the metagame. Teams are forced to run a Grimmsnarl hard counter for consistency. Two RNG-dependent checks are no good because of the unpredictability of sleep rolls. You don't need skill at mental games, a cornerstone of playing 1v1, to abuse Grimmsnarl. You just need good luck to beat many teams. Skill is irrelevant because there's little room for mental games against Grimmsnarl.
Now this is only the Gigantamax forme. In the cartridge games, it's confirmed that Gigantamax Pokemon are separately coded formes than their regular counterparts. If we are to ban Grimmsnarl for its G-Max move, we can just ban the G-Max form and keep the Dynamax.
Edit: Added a lot.
