I'm not really used with those pronouncing. @_@
If the Gym Battle against Adrienn is going to be doubles, it can provide further support for most of... it's Pokemon?
Yes, it's kinda underrated with that somewhat decent base stat total, but Aroma Veil in doubles is disturbing, disabling the usage of Taunt which would otherwise shutdown Klefki if used into.
And since most of it's Pokemon are rather slow, Aromatisse might have Trick Room to ensure the slowness of it's team to become the reverse, aka. sweep time. (It probably has Intimidate Granbull.)
If it was singles, then it would be a different story. That's all, I guess.
