Neutral Tips for Cloud vs Rosalina & Luma

As Rosalina, you want to space at a distance close enough where the Cloud player isn't comfortable charging limit, but far enough where you can react to dash attack, down tilt, and dash -> cross slash. If the Cloud is inactive, you can begin to walk Luma forward with jabs to elicit a response. From here you can punish all grounded options on block or whiff. Aerial options often need to be anticipated. If Luma is walked forward, you can catch Cloud's jumps with a retreating up air. Otherwise, you will need to either find a power shield for the back air or micro-space outside the range to have a chance at punishing. Full hop downair can pivot grabbed or directly challenged with uptilt.
