Dair U-tilt is generally good.
Laser him a lot when nothing's happening.
Dair Grab to B-throw can often link (not actually, but if you call the air-dodge) to Nairs or Fairs and proceed to gayness.

Keep your distance or be really close. His F-smash like launches him across the screen.

U-smash to kill at medium-high percents. You can set it up with Dair and then wait for them to try to buffer a defensive option to avoid the grab or U-tilt and then call them for it with U-smash. Only do that at kill percent though, there's no sense staling your best KO move when you have potential pseudo-combos. Failed combos will give you time to laser spam too, so keep that in mind.
Alternatively, you out-camp him so if you force him to approach you can probably powershield U-smash him for a lot of his stuff. Or powershield U-tilt at lower percents for those needed U-tilt --> U-tilt / Fair "combos".
