I don't really play very much. Never even played online outside of friends and tourneys on PC, haha. I almost never fought Robbin in Classic mode. It used to be that back in the day, Brawl, I was absolutely beast with Peach. Not so much any more though lol. I'll probably play more in the coming year.
Gg to you too! Don't worry, Robin's not that common of a character to fight online, and I also don't like fighting Peach's because they usually spam that counterattack but yours was good! Maybe work on using different techniques and strategies so opponents can't predict where you're going to land etc.
