Answer 1

But he doesn't even have a crown...

GEN 9 OU

Iron Crown @ Weakness Policy
Ability: Quark Drive
Tera Type: Fighting
EVs: 252 HP / 252 SpA / 4 Def OR 88 HP / 252 SpA / 168 Spe
Modest Nature
IVs: 0 Atk
- Agility
- Calm Mind / Endure
- Tachyon Cutter / Tera Blast
- Stored Power

He has great bulk overall, so Weakness Policy sets are pretty nice. One Agility allows him to outspeed almost everything in the tier. Calm Mind to set up, but Endure can be used to survive a Super-Effective move that activates the Weakness Policy. Tachyon Cutter is STAB and can break Subs and Sashes, or you can use Tera Blast [Fighting] to make sure that mons like Kingambit don't wall you. Stored Power for obvious reasons. The latter EV spread allows you to outspeed Booster Energy IValiant after 1 Agility, and the former one just gives more bulk.

Have fun using it!

Answer 2

I guess I just really like this guy, so here is another set:

GEN 9 OU SCARF

Iron Crown @ Choice Scarf
Ability: Quark Drive
Tera Type: Fighting / Psychic
EVs: 252 SpA / 252 Spe / 4 Def
Timid / Modest Nature
IVs: 0 Atk
- Psychic / Psyshock
- Focus Blast / Tera Blast [Fighting]
- Tachyon Cutter
- Volt Switch

Not really much to say here. Psychic / Psyshock is STAB and boosted by Tera Psychic. Focus Blast gives some really good coverage against opposing steels and darks, but if you hate Focus Blast (aka 95% of players), you can Tera into Fighting and use Tera Blast. Tachyon Cutter is a really good STAB move. Volt Switch is a good pivot move. This thing's movepool isn't that great, but it can still be somewhat viable.

Have fun using it!

Answer 3

Gen 9 Monotype Calm Mind (Psychic)

Iron Crown @ Leftovers
Ability: Quark Drive
Tera Type: Steel
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Calm Mind
- Tachyon Cutter
- Psychic Noise
- Focus Blast

A Calm MInd set Iron Crown can use on Psychic teams in Gen 9 Monotype. Calm Mind boosting Iron Crown's Special Attack and Special Defense allow it to be a potent wincon. Tachyon Cutter is used for the Steel STAB since it hits twice, meaning it deals more damage than Flash Cannon. Tachyon Cutter hitting twice is useful against bulky Pokemon such as Gliscor and Garganacl. Psychic Noise is used for the Psychic STAB since its Heal Block effect lets it work as a pseudo Taunt, pseudo Knock Off, as well as damaging move, allowing it to 1v1 Pokemon such as Corviknight and Articuno, making it a nice anti Flying tech. Focus Blast allows Iron Crown to hit Steel- and Dark-types such as Kingambit, Empoleon, Heatran, and Hisuian Samurott super effectively. Leftovers is used for the item to give Iron Crown a little HP recovery each turn.
