Project National Dex OU: Break This Core

:hydreigon:

Hydreigon @ Leftovers
Ability: Levitate
Tera Type: Dark (not important)
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Substitute
- Nasty Plot
- Dark Pulse
- Taunt

Hydreigon returns! This time this is a more conventional set (if you consider only one attacking move conventional.)

Gameplan: Substitute in front of Toxapex. Taunt it. Set up. Remove it. Same with Ferrothorn. Both Pokemon can't break Hydreigon's sub in one hit, so they're set-up fodder. However, you only need a +2 to wreck both.

Calcs:

0 SpA Toxapex Scald vs. 0 HP / 0 SpD Hydreigon: 29-34 (8.9 - 10.4%) -- possibly the worst move ever

+2 252 SpA Hydreigon Dark Pulse vs. 248 HP / 48 SpD Toxapex: 181-214 (59.7 - 70.6%) -- guaranteed 2HKO

4 Atk Ferrothorn Power Whip vs. 0 HP / 4 Def Hydreigon: 67-79 (20.6 - 24.3%) -- possible 6HKO after Leftovers recovery

+2 252 SpA Hydreigon Dark Pulse vs. 252 HP / 0 SpD Ferrothorn: 225-265 (63.9 - 75.2%) -- guaranteed 2HKO after Leftovers recovery

Azumarill @ Leftovers
Ability: Sap Sipper
Tera Type: Steel/Poison/Ground
EVs: 252 HP / 212 Def / 44 Spe
Impish/Bold Nature
- Whirlpool
- Perish Song
- Protect/Substitute
- Substitute/Play Rough/Toxic/Knock Off/Aqua Jet/Ice Spinner/Scald/Defense Curl (You get the point, this slot is pretty open. I like play rough for Mega-Lopunny)

As should be obvious, this is a perish trapper. Step 1: Whirlpool, Step 2: Perish Song, Step 3: Profit.

Moveset:

Whirlpool and Perish Song are a necessity. You CAN play around with the last two moves. However, I recommend keeping Protect/Substitute in one of those slots, if not both. Protect allows you to stall out a turn of Perish Song, and gain leftovers recovery. Substitute cannot be broken by either Toxapex or Ferrothorn in 2 hits, which allows you to consistently avoid being Knocked Off. Even 2 crits dont necessarily break sub; from any common move, from either pokemon. More importantly, it allows you to avoid status, without wasting your Tera.

Most of the other moves are irrelevant to this core but, one move has the tiniest of niches. Defense curl lmao. If it is down to a 1v1, you cannot Perish song, as you outspeed both Toxapex and Ferrothorn, so Azu would faint first. It is possible to pp stall with Substitute + Defense Curl, just remember not to click Perish Song.

Tera Types:

Steel and Poison are mostly to avoid being hit by toxic from Pex. Ground can allow you to trap mons with Volt Switch.

Congratulations to Ineros for winning this week of Break this Core!

Our new core will be Mawile-Mega + Tapu Koko!

:sv/Mawile-Mega: :sv/Tapu Koko:

How will YOU break this core? Submissions end Friday!

Tapu Koko @ Heavy-Duty Boots
Ability: Electric Surge
Tera Type: Ice
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Thunderbolt
- U-turn
- Roost
- Hidden Power [Ice]

Mawile-Mega @ Mawilite
Ability: Intimidate
Tera Type: Steel
EVs: 116 HP / 252 Atk / 140 Spe
Adamant Nature
- Play Rough
- Knock Off
- Fire Fang
- Thunder Punch
 
Volcarona @ Heavy-Duty Boots
Ability: Flame Body
Hidden Power: Ground
Tera Type: Steel
EVs: 248 HP / 200 Def / 60 Spe
Timid Nature
- Quiver Dance
- Flamethrower
- Hidden Power [Ground]
- Roost
Just qd in front of either of them and you insta win because maw doesn’t have sucker and koko will lose to Volc just roosting and clicking qd. Maw clicking knock doesn’t matter because once you boost you can just win the game right there because most Koko offenses do not like a boosted Volc.
 
Great Tusk @ Choice Scarf
Ability: Protosynthesis
Tera Type: Ground
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Headlong Rush
- Close Combat
- Knock Off
- Ice Spinner

252 Atk Tera Ground Great Tusk Headlong Rush vs. 0 HP / 4 Def Tera Ice Tapu Koko: 300-354 (106.7 - 125.9%) -- guaranteed OHKO
gg
 
Gouging Fire @ Heavy-Duty Boots
Ability: Protosynthesis
Tera Type: Poison
EVs: 252 HP / 136 Atk / 32 SpD / 88 Spe
Jolly Nature
- Dragon Dance
- Flare Blitz
- Earthquake
- Morning Sun

Pretty simple set.
Gouging fire is a great check to M-Mawile and Tapu Koko. The given EVs spread allows Gouging Fire to outpseed Tapu Koko at +1 and OHKO it with Flare Blitz (Earthquake at +1 2HKO's Tera ice Tapu Koko). It also OHKO's M-Mawile with Flare Blitz at +1. M-Mawile can only hit Gouging Fire with Knock Off and Play Rough (it's not running sucker punch in the set) which are both resisted by tera Poison.

NOTE: You can use Earthquake but it is less effective for removing huge threats like this in one go.

CALCS:
+1 136 Atk Gouging Fire Flare Blitz vs. 0 HP / 0 Def Tapu Koko: 282-333 (100.3 - 118.5%) -- guaranteed OHKO
252 SpA Tapu Koko Thunderbolt vs. 252 HP / 32 SpD Gouging Fire in Electric Terrain: 79-93 (19 - 22.4%) -- possible 5HKO

+1 136 Atk Gouging Fire Flare Blitz vs. 116 HP / 0 Def Mawile-Mega: 408-480 (151.1 - 177.7%) -- guaranteed OHKO
136 Atk Gouging Fire Flare Blitz vs. 116 HP / 0 Def Mawile-Mega: 270-320 (100 - 118.5%) -- guaranteed OHKO
252+ Atk Mawile-Mega Play Rough vs. 252 HP / 0 Def Tera Poison Gouging Fire: 59-70 (14.2 - 16.9%) -- possible 6HKO
252+ Atk Mawile-Mega Knock Off (97.5 BP) vs. 252 HP / 0 Def Tera Poison Gouging Fire: 85-101 (20.5 - 24.3%) -- guaranteed 5HKO
