I'm really feeling it! Not that I can play with you or anything, but maybe I can give some tips (though these may seem obvious if you've played enough):
-memorize the colors if you want to play him, it's really not that hard
-be aware of your cooldowns and the stance order, you can't be a sitting duck and slowly shuffle through stances
-take advantage of the monado's range, it's Shulk's best tool.
-Buster at low percents, Smash at high percents, Shield when you're at high percents vs a character that can easily launch you, Jump when you're at high percents vs a character that can't.
