http://www.gamefaqs.com/boards/633202-super-smash-bros-for-wii-u/72833545
Jab frame 5 that's easily shield grabbed since it moves forward
Forward Tilt frame 7(which is good) but has a long cooldown
Down Tilt frame 9 and ducks under a lot of moves(i.e samus' missles)
Up Tilt frame 7 with low cooldown so might be like lucario's but longer
Dash Attack frame 9
Forward Smash frame 19 with a massive hitbox
Down Smash frame 7 which is very good
Up Smash frame 17, massive hitbox
Neutral Air active 7 frames but has landing lag and bad angles so is bad for combos
Forward Air frame 15 and goes from leaning back to sword out immediately, meaning it's amazing for trades. spikes and has 15 frames of lag
Back Air frame 9
Down Air frame 11 that spikes and is active 26 frames, which is pretty good considering falcon's dair is frame 14 and relatively fast
Up Air frame 6 and active 19 frames
Neutral B frame 19 but active for a long time
Side B frame 8 and multihits
Up B frame 7 and a massive hitbox
Down B is limit break which takes about 6 seconds to fully charge
Cloud can then use limit break once on any of his specials.
Cloud's Neutral B becomes a multihit, much bigger, and much more powerful.
Cloud's Side B becomes more powerful and kills horizontally. Also gains invinc on startup
Down B becomes a swirling attack that KO's off the top and has a camera angle similar to Mac's KO punch
