0224 Octillery

None of Octillery's charge moves are cheap in energy, therefore Mud Shot or Lock-On are necessary for its superior energy generation. The former can provide some useful Ground-type coverage, but its damage output is still poor. Water Gun has much better STAB damage output, and could work to apply more consistent damage, but isn't likely going to get to use more than one charge move in a fight. 

Octazooka gets STAB, providies a debuff utility, and is among the cheaper charge moves energy-wise. Water Pulse isn't a good charge move at all, nor does it provide extra coverage, but its higher STAB damage enables it to close out fights slightly better. Aurora Beam isn't a good charge move either, but wide coverage against common typings is valuable. 

Poison-type damage isn't very relevant in PvP, but Gunk Shot has a niche in Great League against the popular Azumarill and other Fairy or Grass-types. The debuff utility of Acid Spray can be useful in certain scenarios, but it doesn't provide enough significant advantages for Octillery to justify a recommendation for it. 

Octillery is a mono-Water type with below-average bulk due to its higher ATK stat, and a very difficult moveset. None of Octillery's charge moves are particularly good, and they all require at least 50 energy to use, which makes Octillery very slow at applying shield pressure. The utility from Acid Spray and Octazooka are more of a gimmick at best, but Octillery lacks powerful moves to follow up and KO the opponent after they have been debuffed. Overall Octillery doesn't stand much of a chance in PvP, unless it gets a significant rework to its moveset. 

Octillery has a max CP of 2315, which isn't enough to reach the CP cap of Ultra League. The same problems that plauge it in Great League haven't gone away either. 

Octillery might be more viable as a seafood snack than an actual PvP candidate.
