Season 7 of GO Battle League is heading toward its first Ultra League and Premier Cup session in Pokémon GO. The next two weeks will consist of battles limited to the usual CP cap of 2500 CP. These two are some of the most popular and toughest sections of the entire GO Battle League season, so you have a challenge ahead if you want to level up. To help here’s our Pokémon GO Ultra League and Premier Cup guide showing you the best Pokémon for your teams in March 2021.
Best Ultra League Pokémon for March 2021
The Ultra League will begin in Pokémon GO on Monday, March 15th at 4pm Eastern Time. Players will be able to complete for the next two weeks with Master League taking over on March 29th at 4pm ET. Below we have broken down the best Pokémon to use on your Ultra League team in March 2021. Some of these will require Candy XL to power up fully to their most competitive level. These are marked with (XL) if they would not appear on the list otherwise. You always want to get as close to the 2500 CP cap as possible, with the ideal IVs usually being low Attack with high Defense and HP.
For your team you usually want to pick one or two from this list then fill in type gaps using the other fields. See what damage they will resist and what they might be weak to. Then try to make sure you have no clear type that will wipe out your team or you might struggle against in other ways.

| Cresselia | Psychic | Psycho Cut | Grass Knot, Moonblast, or Future Sight | Psychic, Fighting | Bug, Dark, Ghost |

Those are the best Pokémon for your Ultra League team in March 2021, but there’s another option available with the Premier Cup.
Best Premier Cup (Ultra) Pokémon for March 2021
The Premier Cup uses the same 2500 XP limit as the Ultra League but with two other restrictions. No Legendary or Mythical Pokémon are allowed. You would think that’d just mean the list above is good as long as the entry isn’t restricted. However, it changes the meta so much that the tiers get all reshuffled. To help, here’s our picks for the best Premier Cup Pokémon for your team in March 2021.
Just like above, some of these may require Candy XL to reach their full potential. We labeled with (XL) when they would not appear on the list otherwise.
