https://www.pokemonsleep.net/en/news/313931363234363437343432313639383537/>Each time a Ghost-type helper Pokémon brings you ingredients during regular helping, it will have one extra.As an example, Gengar with 2x Herbs, 4x Mushrooms, 6x Mushrooms, will temporarily be 3x/5x/7x instead
>The chance of a Ghost-type helper Pokémon’s main skill being triggered will be multiplied by 1.5.>Main skill levels of Ghost-type helper Pokémon will be boosted by 1.These skill boosts are most relevant for Drifblim and Mimikyu, which are the most recently introduced ghosts, both being skill specialists which were previously absent.
However, being that they are so new, you're unlikely to have one ready to make the most of this bonus.
Gengar and Banette are Charge Strength S users, but it's not a priority for them. Skeledirge has Charge Energy S so it'll be a little more energetic if you have one.
So, I wouldn't worry so much about not having a ghost ready, I'll only be running my BFS Gengar myself, and having to roll with the other two berries. Best for me would be stuff like Electric, Fire, Water, and Grass.
E-Zzz Travel Tickets are there to reroll if you get an unfavorable set of berries, make sure you always have a couple handy since you can only get one per month from the regular sleep exchange.
