Playing more is definitely the right advice. Aggressive play can really play hell with some players and work well with some characters, but it's not a merit of skill or the best thing to be doing at all times. Branching out with your Ganon would be a good idea. Get used to not always pushing on your opponent but also feeling them out and punishing their mistakes, or taking advantage of their bad habits. The game is very thought based, so while tech is nice, the smarter player will always win. Work on your ability to process during your games, and you'll go far.
