0683 Aromatisse

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. 

As a Fairy-type, Aromatisse competes very closely with Clefable and Slurpuff, with almost identical results due to similar bulk and charge move timings. Aromatisse's flavor compared to its Fairy rivals is its access to Electric-type coverage in the form of Thunderbolt (and Charge Beam for a different style of play). This lets Aromatisse threaten Water Pokemon and perform slightly better vs Steel-types (when shields are down) that Clefable is walled against, while also having a hope against Poison-types. Charge Beam is likely not the most optimal use of Aromatisse, as it gives up strong fast move damage output to chase its rather costly charge moves, but can throw a curveball against unsuspecting opponents. 

Aromatisse and Clefable are almost identical in this league, and their performances are very similar due to their similar playstyle and stats. XL Candy is required to enable Aromatisse to reach the CP cap of this league, and like other "Charmers" Aromatisse can swing a lot of matchups to its favor if given both shields. However its shield pressure is quite lackluster. 

With at least 1 shield Aromatisse can claim some wins against the popular Dragon-types in this league, but Togekiss is more suitable for Master League.
