0080 Slowbro(Galarian)

Confusion deals slightly more damage than Poison Jab, while the latter provides slightly more energy gains. Either can be viable depending the typing coverage that's more preferable. Poison Jab is generally preferable as it is unique to Galarian Slowbro relative to its Slowpoke-family counterparts, and is a slightly better move in general.

Surf is Galarian Slowbro's cheapest Charged Attack and offers additional coverage against Ground-type Pokemon. Sludge Bomb  is a good well-rounded charge move. Psychic could be chosen for its STAB Psychic-type coverage, which has similar stats. Focus Blast demands too much energy to see consistent use (especially with shields up), but its wide coverage and devastating damage may catch opponents off guard. 

Galarian Slowbro's interesting Poison/Psychic typing and movesets makes it quite solid against Grass and Fairy Pokemon in the meta (including Azumarill), picking various Fighting-types as well. However Dark-types with Counter and Deoxys Defense Forme tend to be more of a challenge. Access to Surf gives Galarian Slowbro a decent amount of spammability and damage consistency. The main obstacle holding Galarian Slowbro back is its weaknesses to Ghost, Dark, and Ground, and there are plenty of users of those types in Great League. Nonethless, Galarian Slowbro can find use in some themed cups to make use of its rather unique typing and coverage.

Much like in Great League, Galarian Slowbro's performance is similar in Ultra League. The decision on moveset options will have a meaningful impact on various matchups, with some favored over others. Its weaknesses still plague it in this league, further complicated by Giratina's omnipresence in the metagame.

Bro this G bro ain't got no stats for ML, bro.
