Pokemon Go best Ultra League team | Go Battle League Season 9

Becoming an Ultra League champion in the Pokemon Go Battle League is no easy task, but a team made up of these best-in-class Pokemon should put you on the road straight to victory.

The Go Battle League is Pokemon Go’s competitive PvP mode that allows Trainers around the world to go head-to-head with their best fighters and earn some great rewards along the way. Each season, the ranks reset, so there’s always a fresh challenge to find.

There are three leagues to compete in – Great League, Ultra League, and Master League – but right now we’re focusing on the Ultra League. This is Go Battle League’s mid-tier competition, where XL Candy is essential and Legendaries start to emerge.


It’s not entirely without restriction, though. Pokemon must be under 2500 CP to enter, so you’ll need a team of fighters that reach their maximum potential just before that level. Let’s take a look at the best Pokemon to use in the Ultra League.


Best team for Pokemon Go Ultra League

Pokemon Go Ultra League

One of the best teams Trainers can use in Pokemon Go’s Ultra League is Registeel, Cresselia, and Swampert, as these are three of the strongest fighters in the meta and provide a good range of coverage against common enemies.

As always, it’s impossible to say what a truly ‘best’ Ultra League team is, as it really depends on the opponents you’ll go up against. For example, Registeel may be king, but it will always be weak against a powered-up Swampert.


Having said that, there are a few Pokemon that will perform well in most situations. Many of these require XL Candy to be viable, but not all Trainers have reached that level yet so we’ve included some non-XL recommendations, too.

Best Pokemon for Pokemon Go Ultra League

Registeel (XL)

Pokemon Go Ultra League Registeel

  • Fast Move: Lock-On
  • Charged Moves: Focus Blast and Flash Cannon
  • Resistances: Poison, Normal, Flying, Rock, Bug, Steel, Grass, Psychic, Ice, Dragon, and Fairy
  • Weaknesses: Fire, Ground, and Fighting

The Legendary titan Registeel is, in our opinion, the king of the Ultra League. It has access to the best energy-generating Fast Move in the game, an incredible amount of resistances, and a max CP of 2447, which is just under the Ultra League cap.

That Fast Move we mentioned? It’s Lock-On, and you’ll need it. With this, you’ll be able to unleash the powerful Charged Moves Flash Cannon, which benefits from STAB, and Focus Blast, which adds some useful Fighting-type coverage.


Galarian Stunfisk (XL)

Ultra League Galarian Stunfisk

  • Fast Move: Mud Shot
  • Charged Moves: Rock Slide and Earthquake
  • Resistances: Poison, Rock, Electric, Fairy, Flying, Bug, Steel, Normal, Psychic, and Dragon
  • Weaknesses: Fire, Water, Ground, and Fighting

Galarian Stunfisk has become an unexpected champion in the Pokemon Go Battle League, ranking as one of the best in both the Great League and the Ultra League. When powered up with XL Candy, it can take down powerful foes like Cresselia, Melmetal, and Togekiss.

Go for Mud Shot as your Fast Move, as it has really great energy generation. Then, for Charged Moves, you’ll want Rock Slide for its low cost to help you destroy your opponent’s shields, and Earthquake for some impressive STAB damage.

Abomasnow (XL)

Abomasnow Pokemon

  • Fast Move: Powder Snow
  • Charged Moves: Weather Ball (Ice) and Energy Ball
  • Resistances: Electric, Grass, Water, and Ground
  • Weaknesses: Fire, Flying, Poison, Rock, Bug, Steel, and Fighting

Abomasnow is one of the top performers in the Ultra League when powered up with XL Candy. It does have quite a few weaknesses, but it can now reach the league’s CP cap and benefits from a fast moveset that can take down opponents before they even know what’s hit them.


Powder Snow is the best Fast Move available thanks to its fast energy generation. Then, when it comes to Charged Moves, you’ll want a combination of Weather Ball (Ice) for its low cost and ability to be spammed, and Energy Ball for great STAB damage and extra coverage.

Trevenant (XL)


  • Fast Move: Shadow Claw
  • Charged Moves: Shadow Ball and Seed Bomb
  • Resistances: Electric, Fighting, Grass, Ground, Normal, and Water
  • Weaknesses: Dark, Fire, Flying, Ghost, Ice

Trevenant only just made its debut during 2021’s Halloween event, but it’s already lining up as one of the best Ultra League competitors with the ability to beat some of the biggest contenders such as Giratina (Altered Forme), Melmetal, Cresselia, and Swampert.

When deciding Trevenant’s Fast Move, it’s an easy choice, as Shadow Claw has better damage output and faster energy generation. When it comes to Charged Moves, start with the low-cost Seed Bomb for baiting shields, then follow up with the deadly Shadow Ball for huge damage.


Giratina (Altered Forme)

Giratina Altered Forme

  • Fast Move: Shadow Claw
  • Charged Moves: Dragon Claw and Shadow Sneak
  • Resistances: Normal, Fighting, Bug, Electric, Fire, Grass, Poison, and Water
  • Weaknesses: Dark, Dragon, Fairy, Ghost, and Ice

For many Trainers, the bulky and devastating Giratina (Altered Forme) is the ultimate choice in the Ultra League. It does have quite a few powerful counters, but if you can avoid them, it will have no problem taking down the majority of the Go Pokedex.

Shadow Claw has a good balance of damage and energy gain, so opt for that as your Fast Move. Dragon Claw is the superior Charged Move, as it has STAB and can be spammed, while Shadow Sneak is a good second choice if you can afford it.


Ultra League Swampert

  • Fast Move: Mud Shot
  • Charged Moves: Hydro Cannon and Earthquake
  • Resistances: Electric, Steel, Rock, Poison, and Fire
  • Weaknesses: Grass

Now for a more accessible Pokemon that doesn’t need XL Candy. Swampert is an excellent Water/Ground-type, which means it only has one weakness (Grass) and can take down powerful Steel-types like Melmetal and Registeel, as well as the Legendary Giratina.

Mud Shot is the best Fast Move for energy generation, so choose that. Swampert excels with Hydro Cannon, which you can only get from Community Days or with an Elite Charged TM, but Earthquake is a solid backup Charged Move otherwise.



  • Fast Move: Psycho Cut
  • Charged Moves: Moonblast and Grass Knot
  • Resistances: Fighting and Psychic
  • Weaknesses: Bug, Dark, and Ghost

While many Legendaries need the Master League to unleash their true power, Cresselia performs best right here in the Ultra League. With fantastic bulk and a max CP just above the cap, it’s perfectly positioned to take down big players like Giratina and Swampert.

Cresselia has two great Fast Move options: Choose Psycho Cut for solid energy generation or Confusion for STAB damage. Moonblast is the clear winner for Charged Moves, with Grass Knot as a second choice for extra coverage if you have access to it.


Snorlax in Pokemon Go

  • Fast Move: Lick
  • Charged Moves: Body Slam and Earthquake
  • Resistances: Ghost
  • Weaknesses: Fighting

Thanks to its resistance to Ghost-type moves, Snorlax is a brilliant choice to take down Giratina (Altered Forme), as well as Cresselia and Trevenant. Snorlax is also a relatively accessible option, as it’s been in Pokemon GO since the early days and many Trainers have one.

Snorlax only has access to two Fast Moves, and Lick is the only one you should consider. Body Slam is the superior Charged Move with a relatively low cost, so make sure you have that. If you can afford a secondary move, Earthquake is a good choice for dealing huge damage.
