I'm delighted to see discussions revolving around niche mons in the OU metagame thread lately; it warms my heart to see people experimenting with Pokemon that have a lot of untapped potential, especially with all the Tapu Bulu discussions recently. So I want to share a few niche sets on niche Pokemon that I've been using to surprisingly good effect in OU lately.
Duraludon @ Choice Specs
Ability: Light Metal
EVs: 4 HP / 36 Def / 252 SpA / 216 Spe
Timid Nature
IVs: 0 Atk
- Draco Meteor
- Steel Beam
- Thunderbolt / Thunder (for rain teams)
- Flash Cannon / Body Press / Stealth Rock
So Duraludon is an absolute monster with Specs for several reasons, and I've been using it as a lure and unconventional answer for unique combinations of threats across OU. Let me explain the EVs quickly before I jump into the other attributes. 216 Speed EVs with a Timid nature bring Duraludon's total speed up to 286, enough to outpace Timid / Jolly base 80 speeds such as DD Dragonite before a boost. 252 Special Attack for full investment, and a little HP and Defense investment to compliment Duraludon's excellent physically defensive profile. No investment is needed for Duraludon's Special Defense as no amount of reasonable EV investment would save its specially defensive profile without running Assault Vest. (As a heads up, I highly recommend running Duraludon with Grassy Terrain support from a Pokemon such as Rillaboom or Tapu Bulu).
So now, why would you use Duraludon? There are three reasons; power, STAB combination, and specific critical resistances on the Physical side. First, let's look at some damage calculations against some bulky threats (only bulky calcs, you can imagine what would happen to more frail targets).
252 SpA Choice Specs Duraludon Thunderbolt vs. 248 HP / 92 SpD Corviknight: 286-338 (71.6 - 84.7%) -- guaranteed 2HKO after Leftovers recovery
252 SpA Choice Specs Duraludon Thunderbolt vs. 252 HP / 4 SpD Toxapex: 204-242 (67.1 - 79.6%) -- guaranteed 2HKO
252 SpA Choice Specs Duraludon Draco Meteor vs. 252 HP / 0 SpD Buzzwole: 499-588 (119.3 - 140.6%) --
guaranteed OHKO
252 SpA Choice Specs Duraludon Steel Beam vs. +1 (Calm Mind Boost) 252 HP / 0 SpD Clefable: 474-558 (120.3 - 141.6%) --
guaranteed OHKO
252 SpA Choice Specs Duraludon Flash Cannon vs. 252 HP / 0 SpD Clefable: 408-480 (103.5 - 121.8%) --
guaranteed OHKO
252 SpA Choice Specs Duraludon Draco Meteor vs. 248 HP / 0 SpD Multiscale Dragonite: 301-355 (78.1 - 92.2%) -- guaranteed 2HKO
252 SpA Choice Specs Duraludon Thunderbolt vs. 252 HP / 4 SpD Slowbro: 332-392 (84.2 - 99.4%) -- guaranteed 2HKO
252 SpA Choice Specs Duraludon Draco Meteor vs. 248 HP / 8 SpD Volcanion: 325-384 (89.5 - 105.7%) --
37.5% chance to OHKO
36 Def Duraludon Body Press vs. 252 HP / 252+ Def Blissey: 244-288 (34.1 - 40.3%) -- guaranteed 3HKO
36 Def Duraludon Body Press vs. 0 HP / 0 Def Heatran: 128-152 (39.6 - 47%) -- guaranteed 3HKO after Leftovers recovery
36 Def Duraludon Body Press vs. 0 HP / 0 Def Bisharp: 272-320 (100.3 - 118%) --
guaranteed OHKO
Duraludon outspeeds almost all of the Pokemon that it would be tasked with handling and fires off powerful attacks more easily than its Dragon-type contemporaries, thanks to the mind games that its Steel / Dragon typing brings. Compressing the role of handling numerous Dragons, Fairies, and Waters into a single slot is vital within team building. It allows you to free up space for more specified coverage options on your other Pokemon, in addition to being able to run more specific archetypes.
Draco Meteor and Steel Beam are your nuclear STABs and will maim almost anything they come into contact with that isn't immune to it. Thunderbolt is Duraludon's best coverage option and should always be on your set (unless you're running a Rain team, in which case, run Thunder). The last slot is a toss-up depending on your specific needs. Flash Cannon is secondary Steel STAB that still nails some impressive damage thresholds and does not have the nasty recoil of Steel Beam. Body Press can be an interesting surprise for chunked Blissey and offensive Heatran sets (especially since Duraludon outspeeds both of them), while Stealth Rock provides some surprise utility (especially if your Choice Specs is knocked off).
Duraludon's naturally good physical bulk of 70 / 115 with Steel / Dragon typing and slight investment of 4 HP and 36 Defense brings its total HP and Defense up to 282 and 275. This investment is a nice additional buffer for taking certain physical blows from bulkier Pokemon sets, even super effective hits in some cases, which Duraludon can then OHKO in return from max health, or with chip in some cases.
0 Atk Buzzwole Drain Punch vs. 4 HP / 36 Def Duraludon: 186-218 (65.9 - 77.3%) -- guaranteed 2HKO (Dura outspeeds and OHKOs in return)
252+ Atk Choice Band Barraskewda Liquidation vs. 4 HP / 36 Def Duraludon: 94-111 (33.3 - 39.3%) --
guaranteed 3HKO (Dura OHKOs and can live two hits with a minuscule chance to live three, especially with Grassy Terrain support)
252 Atk Dragonite Earthquake vs. 4 HP / 36 Def Duraludon: 192-228 (68 - 80.8%) -- guaranteed 2HKO
252 Atk Dragonite Earthquake vs. 4 HP / 36 Def Duraludon in Grassy Terrain: 98-116 (34.7 - 41.1%) --
66% chance to 3HKO after Grassy Terrain recovery (Even less damage dealt with Grassy Terrain, Duraludon outspeeds and has a high chance to OHKO even through Multiscale, and will always OHKO with chip damage)
36 Def Duraludon Body Press vs. 0 HP / 4 Def Magnezone: 120-142 (42.7 - 50.5%) -- 1.2% chance to 2HKO, 252+ SpA Choice Specs Magnezone Thunderbolt vs. 4 HP / 0 SpD Duraludon: 210-247 (74.4 - 87.5%) -- guaranteed 2HKO (if Specs Zone is switched in to trap Duraludon, Magnezone will always be outsped and, with chip, always 2HKO'd)
252+ Atk Choice Band Rillaboom Grassy Glide vs. 4 HP / 36 Def Duraludon in Grassy Terrain: 51-60 (18 - 21.2%) --
possible 7HKO after Grassy Terrain recovery (Adamant Rillaboom is always outsped and OHKO'd by Duraludon's Draco Meteor or Steel Beam).
To summarize, Duraludon's power, defensive utility, and STAB combination have a good place on multiple OU teams.
Glastrier @ Assault Vest
Ability: Chilling Neigh
EVs: 252 HP / 252 Atk / 4 Def
Adamant Nature
- Avalanche
- High Horsepower
- Crunch
- Close Combat
This Pokemon can be nigh unkillable with the proper support, and under Trick Room is pure evil. While Ice is a notoriously bad defensive typing, its defensive stats of 100 / 130 / 110 is absolutely nothing to sneeze at. To show you what I mean, here are some specific calculations against it, along with the follow-up that Glastrier can provide. (As with Duraludon, I recommend Grassy Terrain support or at the very least Defog / Rapid Spin support)
0 SpA Heatran Magma Storm vs. 252 HP / 0 SpD Assault Vest Glastrier: 168-198 (41.5 - 49%) -- 78.9% chance to 2HKO after trapping damage
252+ Atk Glastrier High Horsepower vs. 252 HP / 0 Def Heatran: 472-556 (122.2 - 144%) --
guaranteed OHKO
252 SpA Blacephalon Overheat vs. 252 HP / 0 SpD Assault Vest Glastrier: 294-348 (72.7 - 86.1%) -- guaranteed 2HKO
252+ Atk Glastrier Crunch vs. 0 HP / 0 Def Blacephalon: 346-408 (140 - 165.1%) --
guaranteed OHKO
4 Def Ferrothorn Body Press vs. 252 HP / 4 Def Glastrier: 116-138 (28.7 - 34.1%) -- 1.9% chance to 3HKO
252+ Atk Glastrier Close Combat vs. 252 HP / 4 Def Ferrothorn: 246-290 (69.8 - 82.3%) -- guaranteed 2HKO after Leftovers recovery
252 SpA Choice Specs Dragapult Draco Meteor vs. 252 HP / 0 SpD Assault Vest Glastrier: 163-193 (40.3 - 47.7%) -- guaranteed 3HKO
252+ Atk Glastrier Avalanche vs. 0 HP / 4 Def Dragapult: 296-350 (93.3 - 110.4%) --
62.5% chance to OHKO
252 SpA Volcarona Flamethrower vs. 252 HP / 0 SpD Assault Vest Glastrier: 186-222 (46 - 54.9%) -- 61.3% chance to 2HKO
+1 252 SpA Volcarona Flamethrower vs. 252 HP / 0 SpD Assault Vest Glastrier: 278-330 (68.8 - 81.6%) -- guaranteed 2HKO
252+ Atk Glastrier High Horsepower vs. 0 HP / 4 Def Volcarona: 175-206 (56.2 - 66.2%) -- guaranteed 2HKO
252+ SpA Choice Specs Volcanion Flamethrower vs. 252 HP / 0 SpD Assault Vest Glastrier: 300-354 (74.2 - 87.6%) -- guaranteed 2HKO
252+ Atk Glastrier High Horsepower vs. 248 HP / 0 Def Volcanion: 212-250 (58.4 - 68.8%) -- guaranteed 2HKO
0 Atk Landorus-Therian Earthquake vs. 252 HP / 4 Def Glastrier: 118-141 (29.2 - 34.9%) -- 11.1% chance to 3HKO
252+ Atk Glastrier Avalanche vs. 252 HP / 164+ Def Landorus-Therian: 396-468 (103.6 - 122.5%) --
guaranteed OHKO
Those are high-powered, mainly STAB super effective hits. Now imagine what standard neutral hits accomplish? Glastrier uses its hard-hitting 145 Attack stat (same as Landorus-T) with its fantastic natural bulk and great coverage to maim teams and works wonderfully as a late game "slow-cleaner." Your opponent is either pressured into making decisions and risky switches they wouldn't want to make if they're aware of Glastrier's Assault Vest, or if they're unaware of the set, and then will lose their Heatran or Blacephalon because they went for Stealth Rocks or a STAB Fire move. Chilling Neigh also means that once Glastrier gets a kill and boosts its attack by +1, it becomes exponentially harder to switch into. It's a reasonably simple set compared to Duraludon but an extremely effective one.
