Remember the days when Fluffy RM was a heat set...
OMFL Week 1 is done, and I've done well with it in friendlies/ladder, so here's a team showcase / sample submission. This team's win plan is pretty simple: Break down the core defensive pieces with Lucario, Zapdos and Moon, and
Get Enamorus-T or Roaring Moon in a position where they can clean up. Intim Corviknight and Regen Vest Meloetta form a potent defensive core while also serving to pivot in your
click the pokemon for the team!
I don't think I have to explain what Corviknight does. Intimidate stops most of the physical attackers in their tracks, Brave Bird chunks things on the switch so you can use U-Turn to get in your more threatening mons, and Defog keeps the field clear of Stealth Rocks for Enamorus-T.
MGLO Lucario is still good! Aura Sphere > Focus Blast because screw you, I like hitting my opponent. Close Combat puts immense pressure on the most common RegenVesters, 2hkoing most of them. Steel Beam, especially at +2, scares out almost anything else. Big Damage with the potential to tear the entire midgame apart.
Turns out, 100% accurate Thunder and Hurricane are really good! Zapdos is also a natural check to the powerful flying type offensive threats common in the tier-- Talonflame in particular hates to see this. It's hardly a permanent answer to its Galarian Counterpart, but it can switch in against non-banded sets and deal big damage. U-Turn again allows you to pivot into other threatening options. This is your main way to defeat most Corviknights in the midgame.
Has great natural synergy with Corviknight and Zapdos, sponging the special hits that they can't take as well. Low Kick puts pressure on opposing Goodra-Hisui and other Steels. Thunderbolt means Corv doesn't sit in front of you for days. I firmly believe this is the best Regenvester we have, with U-Turn being an amazing momentum tool for a mon that could otherwise be a momentum drain.
This is your primary win condition. Some prefer SFLO on it, but I'm quite the fan of Triage Enam-T. Priority is really nice on a team like this, and Enam's naturally good bulk means you're free to dump as much into offense as you want. This is EVed to creep 0- Hoodra and chunk it hard with Earth Power, but you can easily go full SpAtk or 36 Spe to creep base 50 mons. Draining Kiss + Earth Power hit most of the tier, and Mystical Fire hits the Corviknight that it doesn't.
Fluffy Moon fits on this team as all of a defensive piece, a wallbreaker, and a win condition. Fluffy + naturally good bulk give you great defensive utility and also let you set up much easier. Dual Stab is great coverage, only missing out on Fairies, but you can run Iron Head or EQ over Dragon Claw. Fire Fang is your only real way of dealing with Corviknight, if you haven't gotten rid of it with Zapdos.
The best part of this team is how it's relatively customizable: If different meta threats rise up, you can slot in different moves or EVs without losing the core ideas of the team. Meloetta has different moves it can run, and either of your wincons can be swapped for other threats if you desire.
short Threat List
Lucario and Enam-T put a lot of pressure on Ursaluna, but if Ursa gets a BDrum up it might be lights out. Solid play is enough, most of the time, especially since Ursaluna sets lacking Heavy Slam / Gunk Shot can't hit Enam-H for good damage. Still, though, Ursaluna (and to a lesser extent, TriageDrum Chesnaught) put a lot of pressure on you from the start of a match.
Gapdos' counterpart from Kanto is a relatively fake answer, especially against Band or BU sets. Enam-T will not OHKO at +0, but it will revenge with the slightest chip. Be very careful to preserve your Zapdos if you see a Gapdos on preview.
If you lose Corv early, you will likely lose several other team members to this. If it's running Dazzling, then Enam-T will have to
pray for an Icicle Crash miss to OHKO with Mystical Fire.
