185 Sudowoodo

Virtually any Pokemon blessed with Counter will have it at the top of their PVP moveset list. It has fantastic coverage and sports 4 DPT (Damage per Turn) and 3.5 EPT (Energy Per Turn), making the highest performing move in the PVP meta on average.

Rock Slide provides Sudowoodo with a great STAB move that has high power for a reasonable amount of energy. Stone Edge deals more damage, but its greater energy cost is discouraging. Earthquake rounds out this moveset by providing good coverage next to Rock Slide while being an objectively strong move despite its higher energy cost. The addition of Rock Tomb following the GBL Season 10 update is unimpressive, as its poor damage output and high energy cost discourages its use despite its new debuff utility. 

Sudowoodo has access to some great moves and a decent stat-spread, which means it can definitely operate in the Great League. Rock-type coverage is always in demand, and Sudowoodo can deliver it along with also-coveted Ground type coverage, and the stellar Counter as its quick move. However, other Pokemon in the tier such as Bastiodon and Probopass surpass it in terms of general utility. That said, Sudowoodo's pure rock typing leaves it without a double-weakness to Ground and Fighting, which can make it a better fit for some teams.

Getting closer to 2500 with the advent of Level 50 has helped Sudowoodo somewhat, and yet it still has issues. Notable wins against Pokémon like Talonflame, Galvantula, and even Empoleon make Sudo somewhat tempting. However, it just doesn't quite cut it in the format.

Sudowoodo finds itself in the same situation that it did in the Ultra League, but a bit worse. Forego Sudowoodo for a better Pokemon.
