Draining Kiss allows Primarina to recover itself in addition to the Grassy Terrain, while Moonblast is a stronger STAB. Hyper Voice is a great STAB that hits Pokemon behind Substitute like Iron Boulder or Iron Moth while improving matchups against Steel-types such as Gholdengo, Corviknight, and Heatran. Alternatively, Ice Beam can be used for a better matchup against Ground, like Great Tusk notably, Grass such as Meowscadra, Rillaboom, and Serperior, and Flying-types, while Shadow Ball hits effectively Gholdengo and Psychic-types like Hatterene and Galarian Slowking. Rest is an option to sustain itself in the late game. The spread allows it to outspeed Adamant Kingambit. Tera Poison is a great defensive Tera, allowing Primarina to get rid of its weaknesses to Grass, Poison and Electric-type moves, whereas with Tera Steel, Primarina gains valuable resistances to Fairy, Dragon, Rock for Stealth Rock damage, and Ice-type moves, and an immunity to Poison-type moves, to Toxic, and to Toxic Spikes, in exchange for weaknesses to Fire, Ground and Fighting-type moves.
This set of Primarina only works with Grassy Terrain so Rillaboom is a compulsory teammate for it. Fire, Ground, and Fighting-type will help Primarina to hit Steel-types effectively, while hazards setters and hazards removers will help Primarina respectively to weaken its counters and to get rid of entry hazards. Moreover, wallbreakers are also good teammates to weaken opposite Pokemon.
