Wish I found out earlier, but going to try online; havent any Earthrise Micromasters so thats safe and going to try for not-Grapple, presumably even if it takes a swap that will be another Starscream for a custom.
Hopefully more like Sunstorm than Skywarp but I'd take a Siege Starscream to do that after the way Phantomstrike went and now they're exclusives again :|
