0503 Samurott

Fury Cutter is generally more preferable for its faster energy generation, letting Samurott access its Charge Moves sooner. Waterfall can be effective when shields are in play due to its high STAB damage output, but will decrease the frequency of using Charge Moves. 

Hydro Cannon is mandatory for Samurott due to its low energy cost and high Damage Per Energy (DPE) value. Megahorn is the cheapest Charge Move energy-wise that provides some type of coverage, though this isn't always enough to fight back against certain meta Grass Pokemon. Blizzard is slightly stronger but unappealing due to its huge energy demands. Razor Shell is an interesting option that costs the least amount of energy possible, and has a chance to debuff the opponent, making it a decent move to bait shields. Since Hydro Cannon deals twice as much Damage Per Energy spent and is also quite cheap to use, Razor Shell is generally not recommended due to the lack of coverage and inconsistent debuff procs. Liquidation is just inferior to Hydro Cannon.

As a Water-type, Samurott competes with various other Water-types for a roster slot on the team, but is benched primarily due to its suboptimal moveset, and to a lesser extent, its unimpressive bulk. Access to Hydro Cannon following the Oshawott Community Day is a much needed improvement to Samurott's kit, but Samurott somewhat falls behind other meta Water-types. Megahorn gives Samurott a niche against certain Grass counters, as well as Psychic and Dark-types, but this isn't as valuable against the overall meta. 

Samurott is a few steps down from Swampert in terms of overall performance against the meta. Interestingly enough Samurott actually can beat Swampert in an even fight due to the latter taking neutral damage from Hydro Cannon instead of resisted damage, which is the opposite of the results from Great League. Access to Megahorn is a nice perk due to the common usage of Dark-types in this league, and the combination with Fury Cutter can flip certain matchups against Grass Pokemon if Samurott can successfully land Megahorn or bait with Hydro Cannon. 

Samurott falls behind Kyogre, Swampert, and Gyarados in this league.
