Flareon and Leafeon are becoming better in Breeding Variants, but there is still one competitively-the-worst Eeveelution to fix; Glaceon.
Pokemon Name: Muddy Glaceon (Glaceon-Muddy)
Egg Group: Field
Stats: 80 HP / 60 Atk / 110 Def / 130 SpA / 95 SpD / 65 Spe | BST: 540 (Averaged HP)
Type:
New Moves: Scald, Hydro Pump, Earth Power, Sludge Wave, Recover
Abilities: Unaware | Ice Body
Height: 0.9 m |
Weight: 35.9 kg
Dex Entry: Being able to adapt on the river, Muddy Glaceon figures out how to melt its own ice in order to perform Water attacks. It tend to overdo the melting that result a scalding water. | Although looking a bit sillier looking, it is more resilient than a normal Glaceon.
Competitive Use: Although this Glaceon still have four weaknesses and only gain a resistance to Water, it compensates with slightly better HP (which can reinforce good Defense further with Scald's burn) and Unaware, making physical set-up sweepers much less effective against it, especially since Muddy Glaceon have access to Recover. With Freeze-Dry, most opposing Water-type (including Toxapex) wouldn't bother to switch-in, while Earth Power will make it dangerous against Electric-type. It can serve as a wallbreaker who can ignore stage-based defensive boosts if it hold Choice Specs, or a physical wall with Scald and Unaware to ignore Attack and Special Attack boost.
Is it Overpowered?: It's Special bulk still isn't impressive, so strong Special wallbreakers can at least deliver a 2HKO or even a OHKO (though Unaware means that one should not set-up on Muddy Glaceon as it will just not work). It is also slow, which means it can be easily finished off if sufficiently injured outside of the semi-uncommon Trick Room. Migale Vikavolt will work the best does to naturally very high SpA and Compound Eyes Thunder.
Pokemon Name: Sumo Hitmonchan (Hitmonchan-Sumo)
Egg Group: Human-like
Stats: 97 HP / 105 Atk / 79 Def / 35 SpA / 110 SpD / 76 Spe | BST: 502 (Averaged HP)
Type:
New Moves: Earthquake, Heavy Slam, Iron Head, Knock Off, Poison Jab
Abilities: Thick Fat / Iron Fist | Inner Focus
Height: 1.8 m |
Weight: 223.6 kg
Dex Entry: It is revealed that his variation of Hitmonchan wasn't known in public until they get exported into the Galar mainland. They can deliver punches as much as taking them. | Although they seems more obese than standard Hitmonchan at first, they turned out to simply have another layer of muscle, allowing them to tank physical and ranged hits better.
Competitive Use: Hitmonchan is the competitively worst of the Hitmons, and the reasons should be obvious; Hitmonlee have far better firepower while Hitmontop is better at supporting and use of Technician or Intimidate. With the bigness of Hariyama, Hitmonchan's Special Defense will be put into better use. Iron Fist allows it to power up Drain Punch, Bullet Punch and the elemental Punches to a more reasonable fire power, and can use Bulk Up to both boost its Attack and patch up it's less impressive Defense. It could also instead run Thick Fat to deal with special attacking (and maybe even physical attacking) Fire and Ice threats, especially with Assault Vest equiped.
Is it Overpowered?: 76 Speed is still unimpressive, meaning that it wants to use Mach Punch to take out faster opponent or have speed control supports. It's 105 Attack isn't really all that mighty and will not stand Burn, meaning that Conkeldurr, a fellow Fighting-type with Guts, still overshadows it in term of wallbreaking prowess. That being said, Conkeldurr itself is slower, and Sumo Hitmonchan is comparatively bulkier (combined with Thick Fat), especially if it managed to use Bulk Up, and Sumo Hitmonchan have access to Iron Head to deal with Fairy-type not having a problem with Poison moves.
Pokemon Name: Shock Cursola (Cursola-Shock)
Egg Group: Water 1
Stats: 85 HP / 95 Atk / 50 Def / 145 SpA / 130 SpD / 30 Spe | BST: 535 (Averaged HP)
Type:
New Moves: Thunder, Thunderbolt, Thunder Wave, Yawn, Sludge Wave
Abilities: Static | Perish Body
Height: 1 m |
Weight: 11 kg
Dex Entry: The Shock Cursola had been known for causing a combination of petrification and paralysis on anyone who touched it's electroplasmic body. | New species of Cursola had developed static shocks, allowing it to generate electricity for self-defensive purposes.
Competitive Use: Cursola isn't really horrible, for sure, but it's definitely overshadowed by Galarian Corsola thanks to the pre-evolution's access of Eviolite. This whole new variant of Cursola now have what Galarian Corsola don't, namely Electric-typing which allows resistances to Steel, Flying and Electric, higher HP making it's Special bulk more usable, access of Thunder Wave and Yawn, and of course, BoltBeam coverage. With a Choice Specs or Assault Vest set, it can also play as a terrifying wallbreaker with BoltBeam coverage (with Assault Vest tanking even boosted Special Attacks). Or it can also mess with Yawn, Stealth Rocks, Thunder Wave or Will-o-Wisp to punish switch-ins. Once on a Trick Room, it can become a terror as not many are slower than it.
Is it Overpowered?: It's Speed is still very low, making it prone to be revenge killed, and it's Defense is still problematic, especially now that it is weak to the Physically oriented Ground (though most of them have to watch for Ice Beam or Giga Drian). It would only really shine in a Trick Room team (which is uncommon but more prominent in Doubles), or as a Specs wallbreaker, as Galarian Corsola is still better as a Ghost-type wall than Cursola ever could. In any case, just don't let it face a physical Ground or Dark outside of Trick Room (and watch for Sucker Punch), and you would be fine.
P.S. I definitely won't mind having Sylveon-Protector banned/removed from V2, seeing that Sylveon by itself is in Galar OU at the moment.
