Let's Go Pikachu & Eevee Gloom Best Moveset

Don't let the NFE status fool you. Gloom with Eviolite hits bulk numbers that compete with final forms. Max HP and Defense EVs and Bold nature maximize that, and Stench handles the rest.

Best Build

Let's Go Pikachu & Eevee uses different battle mechanics.

Competitive build content is not applicable for this game. Select a main series game for builds.

Moves

The level-up pool tells the story here. Gloom learns Moonblast and Sludge Bomb naturally, plus enough variety that TMs feel like bonuses. Fairy and Normal coverage extends the reach beyond that.
