Oh boy, just got back from fighting a really good Cloud. His up air is really good. Like really good. Fast falling up air into the ground and a second up air is a true combo up to mid percents that does a sweet 26% total. It's surprisingly fast as well given its massive range and power, making it a good kill move imo. Neutral air with a short hop is lagless too, so Cloud's spacing really puts Shulk's to shame. The unpredictability of his limit break is also really tough to deal with, since it's never really obvious which move he'll bust out unless he's off stage. Definitely a top tier threat.
