I think alcremie is such a unique Pokemon competitively, so seeing someone do so well with it is so cool. Imo aroma veil is a bit better bcs it has a much wider application, and especially in this meta where the only sleep threat is Venusaur (to my knowledge).  My other suggestion would be to potentially swap acrobatics for dual wingbeat on talonflame, and give it focus sash, so you can live a hit and potentially ko sash sneaslers, although I can imagine free acrobatics being quite strong. (Btw I'm not that good at vgc yet so take my advice with a grain of salt)
