Paldean Tauros itself is somewhat worse than Fire Paldean Tauros, or Water Paldean Tauros, however, it boasts a great 110 base ATK with a complementary 100 base SPE.
So I'll give you a few sets.
Banded 'Ros:
Tauros-Paldea (M) @ Choice Band
Ability: Intimidate
Tera Type: Rock
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Close Combat
- Earthquake
- Iron Head
- Stone Edge
This set utilizes Paldean Tauros' superior speed, and ATK to check foes in RU like Drednaw, Altaria, Copperajah, and more. Due to Paldean Tauros' wide physical movepool, Paldean Tauros can obtain some very good coverage moves, such as Iron Head and Stone Edge to hit hard.
However, Banded Tauros can be checked by certain Pokemon like Flamigo, who can set up a swords dance on the switch to punish your switch. That's why I prefer tera rock, to obtain Stone Edge stab, to reduce the risk of getting killed by the abundant flying stab in RU, and to eliminate certain foes who won't be expecting it, like Jumpluff and Masquerain, who would want to either want to Strength sap it (Jumpluff), or Hurricane it (Masquerain).
This set can be also used alongside Choice Scarf.
Bulk up 'Ros:
Tauros-Paldea @ Leftovers
Ability: Intimidate
Tera Type: Rock
EVs: 252 HP / 252 Atk / 4 SpD
Impish Nature
- Close Combat
- Earthquake
- Bulk Up
- Stone Edge
Rock tera is explained in previous set, however, this set takes Paldean Tauros on the more bulky offense side. With Rock tera being more used for defensive use, which also means that you can substitute Tera Rock with Tera Steel.
Leftovers are for passive recovery.
Bulk Up is the main theme of this, abuse intimidate to force switches on physical attackers, and use the time to set up a bulk up. This can snowball up pretty quickly on teams that lack the reliable special attackers.
This can be used with any Paldean Tauros variant with Raging bull replacing EQ.
Doubles 'Ros:
Tauros-Paldea @ Safety Goggles
Ability: Anger Point
Tera Type: Ground
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Close Combat
- Earthquake
- Iron Head
- Rock Slide
Although far outclassed by his cousins, Fire Paldean Tauros and Water Paldean Tauros as an Anger Point abuser, Paldean Tauros still does the job nicely, with access to Earthquake and Rock slide. But you must use this set alongside Frosslass.
Safety Goggles are there just due to the sheer amount of spore abusers in doubles.
This can be used with any Paldean Tauros variant with Raging bull replacing Iron Head.
Froslass (F) @ Aguav Berry
Ability: Snow Cloak
Tera Type: Ice
EVs: 248 HP / 8 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Frost Breath
- Destiny Bond
- Helping Hand
- Light Screen
The only thing Froslass does is use Frost Breath, which is a guaranteed critical hit on an anger point Pokemon, which is Paldean Tauros.
The second thing Froslass does is to set up Light Screen to help with Paldean Tauros' mediocre spdef, that means on the first turn, Paldean Tauros has to use Rock Slide.
Destiny Bond, Helping hand, and Aguav Berry are there to just make it an okay support if you choose to swap out into your flying type before Paldean Tauros terastallizes into ground and uses earthquake.
Fire Paldean Tauros:
Gen 9 RU/UU/OU Offensive Support:
Tauros-Paldea-Fire @ Leftovers / Sitrus Berry
Ability: Intimidate / Cud Chew
Tera Type: Dragon
EVs: 252 HP / 4 Atk / 252 Def
Impish Nature
- Body Press
- Will-O-Wisp
- Protect
- Raging Bull
This set focuses on using Will-O-Wisp to cripple physical targets, which means the EVs are more physically defensive.
If you choose to use Cud Chew, you would need to use Sitrus Berry for the more immediate recovery, although I would recommend you to use Intimidate.
Body Press is good stab that also utilizes impish with 252 defenses.
Protect is there for obvious reasons to help with predicting
Raging Bull is just fire stab that could be utilized to some extent.
I recommend this Pokemon across all three tiers of Gen 9 (when this was written, there was RU, UU, and OU) due to how useful it can be, with great defenses, great support moves and so forth.
It is a solid counter to Chien Pao, somewhat solid counter to many physical attackers that are usually not setup sweepers.
