I think Kylo scales similarly to Palpatine but for the opposition. He's the strongest card in the game against dengaroo (basically a 1 ship list) and almost a blank card against 8ball swarm. As stated above lists with multiple reasonably good ships and no key pieces will be fine, and 4-5 ship lists sound great. Honestly 3 ships may be enough assuming they're all approximately equally as good since most Kylo carriers will melt under concentrated fire.
Scum mindlink seems as strong or stronger than ever, imperial triple ace or miniswarm builds seem good, and rebel bombs or things with bwings seem good.
Kylo also has a weird situation where Kylo lists are best suited against... Other low ship count Kylo lists. This might lead to the meta not melting too hard because of him.
