fthrow->uair owns him (if he has time to use his Reflector after the upair, you can shield it and regrab him for another fthrow->uair
at low percents, dthrow->uptilt or just uptilt juggling own him. Also, he's pretty easy to dthrow, chase, dthrow, repeat.
Take his power if you can, and use it wisely.
Watch out for his smashes, you should always be aware of when you're in fsmash range and you should probably jump to avoid it. You beat him in the air for the most part, just watch out for his Bair, it comes out fast, and I heard that his Nair has high priority. His Fair and Uair are pretty good KO moves, so be careful when you're at higher percents. Watch out for his Dair spike when you're offstage.
You can't really gimp his Side B, unless MAYBE you Stone him out of it. It can spike you, so be careful. His Up B has some starting lag, so if you put him in a position where he has to use it, you can gimp him pretty easily.
