Moves
Wish allows Spritzee to restore its own HP and pass 13 HP boosts to teammates. Protect allows Spritzee to receive its own Wishes when it would otherwise be KOed by a foe's attack, and it can also ease prediction against Choice-locked Pokemon. Moonblast provides Spritzee with a STAB move that hits the Fighting-type Pokemon it aims to check, and it hits most of the metagame at least neutrally, making the most of Spritzee's limited offensive presence. Additionally, Moonblast carries a decent chance to lower the foe's Special Attack, which can come in handy against checks. Covet allows Spritzee to regain an item after switching in on Knock off, which it will do frequently. Alternatively, Psychic allows Spritzee to almost always OHKO Croagunk as well as 3HKO Foongus and Mareanie, making it more difficult to switch into. Calm Mind is used to allow Spritzee to sweep late-game if its checks have been eliminated, as it can slowly boost up while healing itself with Wish. Aromatherapy heals Spritzee's team from status moves, making it the better option on teams that are susceptible to burns or paralysis.
Set Details
The given EV spread and a Bold nature maximize Spritzee's physical bulk and allows Spritzee to pass the largest Wishes possible to its teammates. Spritzee prefers physical bulk over special bulk because its role is to check Fighting-types, which are predominantly physical attackers. The remaining EVs go into Special Attack, Special Defense, and Speed. Eviolite boosts Spritzee's Defense and Special Defense stats, giving it greater bulk and longevity. Aroma Veil is the preferred ability because it gives Spritzee an immunity to certain stallbreaking moves, such as Taunt and Encore.
Usage Tips
Spritzee should be brought in against the Pokemon it checks, most notably Fighting-types that aren't Croagunk. From there, Spritzee can heal itself and its teammates with Wish and Protect. Despite its good bulk, be careful of allowing Spritzee to take super effective hits, especially if its Eviolite has been knocked off, as it can get worn down quickly. However, Spritzee can take most neutral hits, so don't be afraid to attack. If you're running Calm Mind, Spritzee should wait until late in the game to set up, after its checks have been weakened and it has a safe opportunity to set up. If Spritzee is acting as a wincon in a given battle, be careful about letting it get hit by Knock Off, which will limit its eventual setup opportunities. If you're using Aromatherapy, Spritzee can take advantage of the switches it forces by coming in on the Pokemon it checks to quickly heal its team. Be aware of the fact that Spritzee often requires using Protect the turn after using Wish to heal itself, which can give the opponent a free switch or setup opportunity, especially late in the game, and predict accordingly.
Team Options
One of Spritzee's greatest attributes is its ability to form defensive cores. Munchlax and Ferroseed both appreciate Spritzee's ability to take care of opposing Fighting-types and the recovery that Spritzee's Wish passing can provide, and in return, they can handle Steel-types, except Pawniard, and Poison-types, respectively. Mudbray can handle the Steel-, Poison-, and to a lesser extent, Fire-type Pokemon that give Spritzee trouble, and it appreciates the recovery that Spritzee provides it. Hippopotas also makes a good defensive partner for Spritzee, checking Poison-, Fire-, and Steel-type Pokemon and wearing down opposing teams with weather damage, entry hazards, and Whirlwind. Bulky Pokemon without recovery appreciate Spritzee as well. Skrelp, Timburr, Mienfoo, and Croagunk easily take on most of the Pokemon that threaten Spritzee and appreciate Wish support, as they tend to get worn down. Pursuit trappers such as Alolan Grimer synergize well with Spritzee on all team types, as they are able to remove Gastly, which would otherwise render Spritzee useless for a match. If you're running the Calm Mind set, Spritzee appreciates partners that can break down the Pokemon that resist Moonblast for an eventual late-game sweep. Diglett makes a fantastic partner, as it is able to trap nearly all of the Fire-, Steel-, and Poison-types in the metagame and remove them from battle. Ponyta and Larvesta double as Pawniard checks and can check many of the Pokemon that threaten a Spritzee sweep, most notably Foongus, but both are vulnerable to Skrelp and Mareanie. A Pawniard check is essential when using Spritzee, however, making Fighting-types and Flame Body users good partners.
