Aromatisse

Aromatisse is mostly a dex entry, with inadequate stats and movesets to be useful in the meta. Its moderately high STA stat does make it more appealing for gym defense, as resistance to ubiquitous Fighting-type attackers is valuable. As a side note, a Mystery Box (AKA Meltan Box) can be supplemented for the 1 Incense evolution requirement. 

Best PvE Offensive Moveset

• Charm is the stronger fast move for offense.
• Moonblast generally outperforms Draining Kiss on offense. 
• Psychic lacks STAB and is thus a downgrade, but still synergizes well against Fighting-types.
• Charge Beam could pair with Thunderbolt to fulfill a budget Electric-type role, but Electric-type Pokemon are better options. 

Best PvE Defensive Moveset

• Charm hits hard on defense thanks to its high base power plus STAB.
• Charge Beam is pretty poor for defense. 
• Psychic is generally the best charge move for defense, and also provides coverage against Aromatisse's weakness to Poison Pokemon. 
• Thunderbolt is decent for defense, but nothing extraordinary. 
• Draining Kiss doesn't deal a lot of damage even with STAB, but is more likely to be used as a 2-bar move.
• Moonblast is too slow for defense. 

Charm is generally recommended due to STAB and a more direct correlation to Aromatisse's role as a Fairy-type. Charge Beam can be used to generate energy quicker and access charge moves sooner, but generally underperforms. 

Psychic provides coverage against Aromatisse's weakness to Poison-types, while Thunderbolt can be useful against common Water Pokemon and is not resisted by Steel Pokemon. Moonblast and Draining Kiss both get STAB with the former being much stronger, though neither offer any additional coverage.
