Gonna go through and comment on some subs:
Spdef wall
Name of the Pokemon: Malamar
Role(s): Spdef wall, utility, hazard control, attacker
Type: Dark/Fairy
Abilities: Aroma Veil, Immumity, Wonder Skin [H]
Stat Distribution: 90/50/85/115/115/80
Movepool Additions: Moonlight, Moonblast, Knock Off, Haze, Defog, Agility, Recover, Defense Curl, Flamethrower
Movepool Removals: Hypnosis, Psybeam, Psychic, Psycho Cut, Reflect
Custom Elements:
Justification: This thing is just a good utility mon, maybe like a Clef in OU. Has a cool defensive typing to take on special attackers with the stats to back it up. Can recover, defog, knock, as well as stuff like toxic. Can also Calm Mind and be a fat special attacker, I guess. Overall a Splashable pick
Mostly a good sub, I'd just recommend a relative speed nerf or the removal of flamethrower to make an offensive set less appealing, as a set of CM/Moonblast/Flamethrower/Recover with immunity seems like a pretty decent setup stallbreaker that still holds up against offense with speed investment. Also Malamar already knows Knock Off so no need to add it to the moves.
Name of the Pokemon: Florges
Role(s): Special Wall, Cleric
Type: Fairy
Abilities: Flower Veil / Regenerator / Symbiosis
Stat Distribution: 88/65/78/112/154/75
Movepool Additions: Recover, Thunder Wave
Movepool Removals:
Custom Elements:
Justification: Florges, also of Generation 6, has become the definitive special wall. It is not as powerful as Avalugg, but its weaknesses are not quite as pronounced.
By virtue of Regenerator this is also a defensive pivot, huge special bulk+regenerator and few (uncommon) weaknesses may set a very high power standard (compared to Avalugg who can easily be lured with common coverage), and forcing Poison/Steel coverage on special attackers from the get go is... questionable. Personally I think that removal of Regenerator would be the best route to take, if not that then the addition of a secondary type such as Grass and removing Recover to leave it with Wish/Synthesis to give it more common weaknesses and less consistent would also fix the issue.
Name of the Pokemon: Corsola
Role(s): Special Wall, Hazard Setter, Offensive Pivot
Type: Water/Rock
Abilities: Rough Skin, Natural Cure, Regenerator
Stat Distribution: 95/55/75/95/115/55 (BST: 490)
Movepool Additions: Spikes
Movepool Removals: None
Custom Elements: None
Justification: That's right, another forgotten gen 2 Rock-type. I swear I just /randpoked a bunch on Showdown until I got some mons I thought would be cool, but I came up with Magcargo before I thought of a physical wall and I just happened to think Corsola would be cool for the special one. Either way, Corsola already has two great abilities, and Rough Skin made sense here and helps it punish physical attackers so I thought it'd be nice. Its movepool, like Magcargo, has some good and interesting options, like Scald, Recover, Stealth Rock, and Magic Coat, so I didn't think it'd be necessary to add much here, but Spikes just gives it that much more utility on teams that already have Stealth Rock users. Also, I thought it'd be interesting to give it a bit more Special Attack so it'd be an okay bulky offensive pivot with Choice Specs and Regen, it gets Earth Power and Ice Beam along with solid STABs and Hidden Power so that's cool, but probably not optimal so it'd be cool for surprises.
Access to Regenerator makes this a defensive pivot. Outside of that looks good, if your subs win we're looking at a lot of burns lol
Pokemon: Audino
Roles: Special Wall, Cleric, Trick Room Setter
Type: Normal / Fairy
Abilities: Non-Violent* / Regenerator | Magic Guard (HA)
Base Stats: 103 / 60 / 75 / 86 / 126 / 60 (510 BST)
Movepool Additions: Recover, Moonblast
Movepool Removals: Simple Beam, Knock Off
Custom Elements: Non-Violent (Thick Fat clone; receive half damage from Fighting-type and Dark-type moves.)
Uses: Plays similarly to Chansey in OU but less overspecialized and a bit more passive. With Recover, Audino is able to heal itself, especially if running Regenerator. Magic Guard allows it to worry less on passive damage. Non-Violent allows to take half damage from Fighting, essentially making a good counter to Ghost/Fighting coverage. However, its Defense is not that impressive and thus could have hard time dealing with more physical oriented threats, especially those with Steel or Poison moves.
I don't believe 3 viable abilities are necessary here, especially a custom one that will almost definitely be shunned in favor of Magic Guard. Also due to Magic Guard I'd nerf its bulk, the inability to be chipped alongside a typing that has very few weaknesses would probably make it an efficient physical wall (look at Clef in OU as an example of how Magic Guard and typing totally inflates relative bulk) and a very proficient stallbreaker with Calm Mind. You could also just remove Magic Guard and focus on Regenerator and Non-Violent, if you do do this remember to list it as a defensive pivot too.
Physical Wall - Claydol
(Other roles: Hazard control, Calm Mind user, Trick Room setter)
Type: Fairy / Ground
Abilities: Poison Heal / Levitate
Stat Distribution: 91 HP / 52 Atk / 117 Def / 104 SpA / 91 SpD / 52 Spe (507 BST)
Movepool Additions: Dazzling Gleam, Moonblast, Recover
Justification: First and foremost, I've decided the Fairy / Ground typing would be ideal for the main physical wall. Rock, Fighting, and Dark are commonly labeled as "physical types" due to somewhat of a lack of reliable special options for such typings. Fairy / Ground is also, in general, a fresh and solid type combo that provides lots of interesting resistances and weaknesses. In terms of ability, Poison Heal enables it to avoid Toxic and get considerable added recovery every turn, whereas Levitate not only allows it to take on Ground-types but also be a solid remover of Toxic Spikes. The combo of typing and Levitate is also key for it to avoid most STAB combos commonly associated with physical attackers, namely Rock + Fighting and Rock + Ground. Statwise, I wanted to keep things similar to OU levels for new players to be able to pick up with more ease. 100 / 100 would be good bulk, so 91 / 117 would be slightly above average whereas its special bulk in 91 / 91 leaves a bit to be desired but is still decent enough to take on weaker special attackers whose STAB are resisted. I decided it should be rather slow in 52 (again, assuming a metagame where 100 Speed is good) but it would have decent offensive presence with 104 SpA and Calm Mind. Finally, it keeps Stealth Rock and Rapid Spin, making it a solid form of hazard control, but picking both means giving up on a STAB move, giving it some sort of 4MSS (unless its indeed able to forfeit one STAB move without issues, but that depends on the metagame, this is somewhat circumvented by its typing being great offensively but its still dependant on the metagame). It can also run Calm Mind to threaten special attackers alike, but once again, must give up on a hazard control move or a STAB.
Mind nerfing its special bulk by a fair amount? Poison heal+Stealth Rock resistance makes it very resilient to chip and would make it a good counter to a large amount of special attackers too (think of how OU Gliscor, despite poor special bulk, is considered a premeir Heatran check). That or you could just remove Poison Heal entirely as it almost completely outclasses Levitate (neutral to ground already and being immune to Tspikes doesn't matter when you're Poison Heal). So either tweak that special bulk or remove Poison Heal.
Special Wall - Haxorus
(Other roles: Fast Wall, Set up Sweeper, Spikes setter)
Type: Dragon / Steel
Abilities: Bulletproof / Flash Fire
Stat Distribution: 102 HP / 102 Atk / 85 Def / 85 SpA / 102 SpD / 102 Spe (578 BST)
Movepool Additions: Slack Off, Coil, Iron Head, Spikes
Justification: From the get-go, I knew I wanted a Dragon-type as the special wall, resisting typical special types in Fire, Electric, Grass, and Water. Steel complemented it nicely, taking on Psychic-types and giving it plenty of resistances. Flash Fire can be picked to turn the now Fire-type neutrality into an immunity, whereas Bulletproof helps it take random special attacks like Focus Blast, Aura Sphere, and Sludge Bomb. For its stats, making it speedy gives it a Zapdos-like choice of whether or not to invest on Speed. Decent Attack gives it great offensive presence, whereas its special bulk can be pretty good, but could crumble if it goes Jolly. As for moves, Slack Off lets it keep itself healthy, Coil gives it yet another setup option, Spikes gives it a solid hazard choice, and finally Iron Head provides a more reliable STAB. So even though Haxorus is a bit more leaned to the offensive side of the spectrum, it still can be a staple special wall with some rather unique traits.
Bulletproof helping it take Sludge Bomb when it's already Steel-type
Outside of that a bit of a relative physical defense nerf and maybe the removal of Swords Dance and Dragon Dance would skew it more towards Fast Special Wall than "Sweeper with really nice bulk and typing". I just think it's much too offense oriented at this point for it to really be considered a true wall.
Name of the Pokemon: Celesteela
Role(s): Physical Wall, Defoger, Cleric
Type:
Abilities: Volt Absorb / Heatproof / Filter (HA)
Stat Distribution: 97 / 97 / 127 / 107 / 83 / 59 ( BST: 570 )
Movepool Additions: Whirlwind, Roost, Defog, Wish, Aromatherapy.
Movepool Removals: Autotomize, Superpower.
Justification: At normal OU this mon is usually used as a Physical Wall due to its limited amount of weaknesses and huge amount of resistances (Resists Psychic, Fairy, Dragon, Normal, Flying and Steel; strongly reisists Bug and Grass and it's inmune to Ground and Poison, and most of them are usually physically oriented). Now, it obviously suffered from some stuff, such as its weakness to the ever-present Fire and Electric types, which it no can avoidthanks to Volt Absorb and Heatproof. It also likes having a wider supportive monepool on Whirlwind, Roost, Defog, Wish and Aromatherapy.
Quite the power standard to start with. Huge special bulk+only one weakness+100000 resistances+reliable recovery+offensive presence in Heavy Slam+Flamethrower is very powerful. Remember that these original 2 walls are what sets the power standard of the rest of the mod, but if you really want a nearly-ubers level of power you don't have to change it. Also remember that you need a special wall.
Pokemon Name: Cofagrigus
Roles: Physical Wall, Anti-Lead, Calm Mind Sweeper, Trick Room Setter
Types:
Abilities: Mummy / Rough Skin /
Magic Bounce
Stats: 70 / 50 / 140 / 92 / 78 / 40 (BST: 470)
Movepool Additions: Parting Shot, Flash Cannon, Foul Play
Movepool Removals: Haze
Justification: I think that ghost types have a pretty good potential to become physical wall. They have a key immunity to fighting and they almost all have access to Will-o-Wisp, a really interesting defensive move. I choose Cofagrigus to represent that typing because his desing implies that it is more of a defensive-oriented pokemon. This new Cofagrigus has a lot of tool to punish physical attackers: We can think about W-o-W and his signature ability, Mummy, but it has now a lot more toys to play with. His newfound type only has one weakness to fairy, so it doesn't need to worry about the other types of coverage. He also has Foul Play and Rough Skin to help him out. But of you don't want to use it as a big, heavy physical wall, he can also perform a lot more roles. To balance this out, he doesn't have access to reliable recovery, and is pretty weak on the special side.
I think that removing Nasty Plot would dissaude from an OTR set over a wall, Magic Bounce seems a bit out of place compared to the power of his other 2 abilities and would probably always be used in order to dodge Toxic, bounce hazards, etc. I'd recommend removing it if you want the other 2 abilities to still see use.
Pokemon Name: Nihilego
Roles: Special Wall, Hazard Control, Sand Setter
Abilities: Levitate / Unaware /
Sand Stream
Types:
Movepool Additions: Rapid Spin, Haze,
Venom Sheath*
Stats: 101 / 41 / 67 / 127 / 131 / 103
Custom Elements: Venom Sheath | Baneful Bunker clone, but toxifies.
Justification: WIP
Still WIP but I'd just like to comment on A. Venom Sheath sounds super annoying especially on a 'Mon with poor physical defense and B. Is Sand Stream really necessary for something that already has 101/131 special bulk and 2 perfectly viable abilities?
Pokemon: Wailord
Roles: Special Wall, Special Attacker
Type:
Abilities: Water Veil / Oblivious /
Liquid Voice (HA)
Base Stats: 170 / 45 / 45 / 90 / 90 / 60 (500 BST)
Movepool Additions: Slack Off, Boomburst, Calm Mind
Movepool Removals: None
Custom Elements: None
Uses: Wailord is a bulky special wall with a great defensive typing and it isn't even that passive. Thanks to Liquid Voice it now has a powerful STAB in Boomburst and it can boost up with Calm Mind. Wailord's physical bulk is much worse though, so it requires some EV investment to survive powerful physical attacks.
Can't see this ever functioning as a pure Special Wall when it has access to STAB Water-type Boomburst. Would probably run CM/Recover/Boomburst/Ice Beam or whatever to be a slow setup sweeper, doesn't really appeal as a special wall at this point. Boomburst is the obvious suspect here, perhaps removing it and replacing Liquid Voice with an ability like Thick Fat would still leave it with Scald as a good utility STAB. Specs/Scarf Water Spout might also be a thing but that doesn't seem to powerful as it stands.
Overall the subs are looking great, don't take my criticism as anything other than constructive, it's amazing to see so many subs in less than 24 hours. Keep it up!
