Anyone else tried choice scarf / choice band earthquake attackers?
the current meta favours them a lot, as there are limited ground immunities that are also high usage.
corviknight, dragonite, rotom-w and.. maybe orthworm, balloon gholdengo and hydr?
here’s a visual representation of the most common
this means lots of teams rely on great tusk or maybe dondozo, hatterene, etc, as the earthquake check after their immunity is gone. This is assuming they have an immunity in the first place.
this is pretty excellent for the choice ground attackers, of which there are some good options:

hits hard with its EQ and some switch in potential to come in

the best choice user, thanks to its ability to switch into lots of things from iron moth to gholdengo, it can also trade hits with great tusk as early as its third switch in, thanks to its ability

its niche is that it can also pivot out of the ground immune Pokémon that might switch in.
a sample set is below:
Garchomp @ Choice Scarf
Ability: Rough Skin
Tera Type: Ground / Ghost
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Stealth Rock
- Spikes
- Earthquake
- Dragon Claw
There really isn’t a need for coverage moves, except maybe rock slide due to the prevalence of bulkarona everywhere.
Dragon claw is literally only there for four main reasons:
1. OHKO roaring moon/dragapult (EQ can OHKO if it has taken some hazards damage),
2. 2HKO most dragonite/hydreigon or at least hit them on a switch,
3. Deal ~30% or more to most rotom, puts it into KO range from strong neutral attacks from partners, and,
4. to break Gholdengos Balloon. Not a fan of fire fang/Aqua tail etc, as they’re barely ever needed or used. Maybe on banded set.
choice band over choice scarf to 2hko hatterene, do a bit more against dondozo stall teams and Tera fairy garganacl, and reduce the switching cycles with great tusk from about 3-5 cycles to 2-4 cycles. It’s supposed to give you reliable OHKOs on kingambit and iron hands too, although you’ll find they often have Tera flying anyway, so the value isn’t really there.
Scarf is better otherwise thanks to the revenging ability, being able to switch into faster Pokémon like pyro ball cinderace, checking all types of misc threats at the fringes of OU, and forcing out/ forcing Tera with lots of Pokémon’s from gholdengo levels of usage to iron hands. Importantly, You also get 3 switchin cycles with most iron moth due to the higher speed, whereas band only gives you 1-2.
This is a big deal for offensive teams because there are no other high-viability, and reliable, offensive switchins to iron moth. Unless we are counting banded dragapult, because ceruledge ain’t it.
Tera ground for scoring critical KO thresholds, and Tera ghost to give immunity to extremespeed and rapid spin in some miscellaneous niche matchups. Tera steel iron head also has perks against all the Tera fairy Pokémon’s running around, although it might need band to actually put in work against garganacl and dondozo. Terablast electric allows you to do notable damage to corviknight, toxapex and dondozo as well as the Tera flying/water users.

ps , I have a feeling when Chien Pao goes.. dragapult will be filling the hole. A high speed shadow ball with choice specs boosted power and potential Tera ghost support is something that’s already excellent, and it will be more obvious when chien pao banded crunch is no longer taking the limelight. Do you think dragapult might be ban worthy? With a modest nature it can respectively OHKO and 2HKO a long list of offensive/defensive Pokémon, and there are almost no high viability checks.
