Thinking about maining Corrin. Any advice?

[Topaz Pikmin]

I tried out Corrin awhile back and I had a lot of fun with her/him/who cares!
So I was considering maining Corrin along side Meta Knight...only problem is I know jack squat about Corrin aside from what every move looks like.
That being said, is there anything that's super important that I should know about Corrin? What kills? What's his playstyle? What combos does he have? What else should I keep in mind while I play Corrin?

@PK Gaming submitted a really good guide just yesterday.... so I would start there.
