Eh Elwind has Normal type moves and with 37 Attack power could probably KO it due to a higher chance of Critical Hit. That being said, he's currently bogged down with Get Together Events(he's hosting the Video Game Music event and several other events if memory serves). Not sure what Caite has been up to but she's going to be one of the last ones to move, if at all.
I got to poke Aldo to move Mercy(Mimikyu), our Sloth, Cuddles the Wailmer and our Ice Cream blowout host for Felix(Shinx). You don't have to attack Karrablast if you don't want to. What I suggest is just that, a suggestion.
