Answer 1

For use in Gen 9 OU and most other singles formats. (Though not the best up there)

Cetitan @ Sitrus Berry
Ability: Slush Rush
Tera Type: Ice
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
-Belly Drum
-Ice Spinner
-Earthquake
-Ice Shard

Pair this with a snow setter (Chilly Reception Slowking is best for this) for best effect.

Making use of the snow defense boost, Cetitan can get an opportunity to set up a Belly Drum and threaten a sweep thanks to Slush Rush increasing speed. Ice Spinner is used over Icicle Crash due to the 100% Accuracy. Earthquake hits Fire-Types and Steel-Types that resist your Ice-Type moves. Ice Shard is on the last slot to out-prioritize certain priority move users like Mach Punch Breloom. Ice Shard also allows you to deal decent damage should snow end before the sweep is over. Ice Tera enables Cetitan's Ice Spinner and Ice Shard to deal more damage.

Comments

you could also give it heavy slam since its weight is 700.0 kg (1543.2 lbs)

My problem though is that I don't feel like Cetitan particularly bennefits from the steel coverage. Like Earthquake already hits Rock Super Effective and I don't see a particular need to hit any Ice or Fairy-Types Super-Effective.

Maybe if Clefable is added back to the game.

Answer 2

Gen 9 NU Belly Drum

Cetitan @ Sitrus Berry
Ability: Slush Rush
Tera Type: Ground / Dark
EVs: 4 HP / 252 Atk / 252 Spe
Jolly / Adamant Nature
- Belly Drum
- Ice Shard
- Earthquake
- Knock Off

If you feel like using Snow in NU, here is a Belly Drum set for Cetitan it can use on those teams. However, unlike the standard Belly Drum sets you usually see with Ice Shard, Earthquake, and a stronger Ice STAB, this set doesn't use Ice Spinner or Icicle Crash. The reason is because if it does so, Cetitan will run into Pokemon such as Bronzong and Tauros-Paldea-Aqua that can give it trouble. This set instead uses Cetitan's coverage moves to be able to handle those cores that would otherwise give it trouble, and you have Tera if you want to have a STAB move.

With Snow and Aurora Veil support, Cetitan can get off a Belly Drum so it can proceed to break through teams or clean through them if the opposing team is weakened or lacks an answer to Cetitan. Ice Shard is the only Ice STAB move on this set, being useful to vibe check faster Pokemon that don't resist it, which is useful if Snow isn't up. Earthquake allows Cetitan to hit Fire-, Steel-, Poison-, and Rock-types such as Chandelure, Incineroar, Hisuian Typhlosion, Klefki, Copperajah, Diancie, Iron Thorns, and Registeel, Toxicroak, and Tentacruel. Plus, Earthquake offers nice nuetral coverage for Cetitan to hit Pokemon that resist Ice Shard. Knock Off rounds this set's coverage, being able to hit Bronzong, who would otherwise wall you, and being useful to hit remove items from checks such as Vaporeon, and is useful to hit Pokemon such as Rotom-Heat and Tera Steel Flygon. You can consider Play Rough over Earthquake to hit Fighting-types for decent chip if Cetitan doesn't get off a Belly Drum, but Play Rough doesn't really cover anything that Earthquake doesn't already cover. Sitrus Berry gives Cetitan HP recovery back after using Belly Drum so it can avoid being put in range of powerful attacks. Jolly Nature lets Cetitan outspeed the relevant Scarf Pokemon in NU while Snow is up, though you can consider Adamant Nature for more power. Tera Ground is used to make Earthquake STAB, while Tera Dark can be used if you want Knock Off to be Cetitan's powerful STAB move.

You mentioned Knock Off as a tera

Answer 3

Gen 9 Monotype Choice Band (Ice)

Cetitan @ Choice Band
Ability: Slush Rush
Tera Type: Ice
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Icicle Crash
- Play Rough / Ice Shard
- Earthquake
- Superpower / Heavy Slam

A Choice Band set for Snow Ice teams in Gen 9 Monotype. Choice Band gives Cetitan immediate breaking power. Icicle Crash is used for a powerful Ice STAB that has a chance to flinch opposing Pokemon. Play Rough provides coverage against Fighting-types such as Quaquaval, Iron Valiant, Slither Wing, and Heracross. Ice Shard can be used instead for a priority Ice STAB that allows Cetitan to revenge kill weakened Pokemon. Earthquake provides coverage against Steel- and Fire-types such as Gholdengo, Iron Treads, Klefki, Magnezone, Iron Moth, Skeledirge, Ceruledge, as well as Pokemon such as Iron Hands. Superpower is used for a powerful neutral coverage move that is useful against Ice-types and can also OHKO Kingambit. Heavy Slam can be used instead since Cetitan is quite heavy. Slush Rush is used to double Cetitan's speed in Snow.
