OP stolen from Gen 8 OU Break This Core

Amazing artwork by ASKid679!​

Hello and welcome to National Dex OU: Break this Core! In this project you'll be presented with a popular core in the metagame each week and allowed to submit a mon or core of your own to break the presented one.

Every Sunday a popular offensive or defensive core will be posted by your hosts.
Posting will last until Friday where you will have the chance to submit a Pokemon or core to break it.

Rules

• Submission Cycles will last from Sunday to Friday, and Voting Cycles will last from Friday to Sunday.
• You may reserve a Pokemon, however you must state what set you are reserving as well. You will have 12 hours before your reservation becomes invalid and is free to be taken by someone else.
• The same pokemon may be used by different people, however the sets used must be different. For example, if I wanted to submit specs Dragapult, K302 could still use Dragapult, but it would have to be a different set such as DD or Wisp.
• Submissions may only be of Pokemon that are in the current Viability Rankings.
• An explanation is required, although it doesn't have to be too long. Calcs and Replays are not required, however they help to better support your submission and argument.
• Make sure the mons that you've submitted, have viable sets and spreads and can also be prevalent support for a team.
• Please be respectful of others during submission and voting.

Timid Nature
IVs: 0 Atk

- Moonblast

Incredibly Simple Solution, but an effective one regardless. Able to revenge kill both from full health with its STABs, and even if they've managed to gather information that it was Scarf Earlier in the game, you can simply use it as an oppertunity to set up Future Sight, and keep them from trying to come in later, or set up one of your own wallbreakers. Psychic is chosen over Psyshock in order to OHKO Zamazenta through Dauntless Shield, whereas Psyshock would fail to do so.

Tera Type: Steel
EVs: 252 HP / 4 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Hydro Pump
- Volt Switch
- Will-O-Wisp
- Trick

This set doesn't necessarily threaten the core offensively, but it manages to cripple them, scarf makes it outspeed torn which makes it capable of vswitching on torn, for the other 2 it can trick and ruin them and for skeld it can hydro pump after the trick (or maybe even before it if skeld was chipped) it also can vswich if sked/clod tera'ed, and it can will-o-wisp on clod which pressures and also tera steel so it doesn't get toxic'ed.

EVs: 252 Atk / 4 SpD / 252 Spe

EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Substitute
- Waterfall
- Dragon Dance
- Crunch

Mgyara is surprisingly bulky SpDef, especially behind screens on HO teams like it usually is on, it generally doesn't care about any attack Torn-T throws at it and hits back harder. As long as you don't switch this into toxic or will-o-wisp this guy cuts through this core like butter.

Mgyara is surprisingly bulky SpDef, especially behind screens on HO teams like it usually is on, it generally doesn't care about any attack Torn-T throws at it and hits back harder. As long as you don't switch this into toxic or will-o-wisp this guy cuts through this core like butter.

The best way to stop Espathra from snowballing out of control is simply tera ting-lu. Just Tera into Steel, click Whirlwind, boom it's no longer a problem at that given moment. Worried about koko taunting you? Mental Herb has got you covered.

Careful Nature

Tera Dark Clod hardwalls Espa no matter what tricks its running, even if Cyc and Koko have supported it properly. Even Tera Fighting doesn't beat it.

0 SpA Tera Fighting Espathra Tera Blast vs. 248 HP / 252+ SpD Tera Dark Clodsire: 126-150 (27.2 - 32.3%) -- guaranteed 4HKO

Clod can easily break Espa's Cyc provided subs and apply Toxic without running out of Recover PPs.

Other HO teammates beat this Clod set but thats just how Espa HO goes rn so L.
