I played in the Online Hyped Tourney for 3DS last weekend, I was surprised how far I got with Kirby 3233. It was also probably my 4th tourney online. The folks who got me were, Shulk and R.O.B. Though, I was matched against him again. (The Tourney went Swiss, then Top Cut makes it to DE.) From what I remember, Shulk rushed me down quite a lot and I couldn't get any ground on him. The match proceeded better when I used his Monado, I felt like I shielded too much and that gave him quite the advantage. I could of probably won the MU with Monado if I kept pressure on him, and made sure when to attack and pursue.
The match against R.O.B wasn't truly that well also, I perfect guarded all his projectiles but still got caught in his long lasting Aerials. I managed to grab a hold of his Laser, that majorly helps against this Match Up. My memory is quite fuzzy afterwards. I know my jabs couldn't beat his, and I had trouble thinking of ways to approach.
