Sky-types are the harder to control types introduced with the connection of Germa-66. Ichiji, Niji, Yonji, Reiju, and in Whole Cake Island Arc with Sanji, will all have ridiculous air time. You may also use this with Smoker, I believe. If you want to make this easy on you, you could always join an online session with someone for an East Blue Treasure Log mission to give you not one but two trophies (completing one East Blue Treasure Log mission) and play around with any of the Sky-types if you've got them unlocked.
