is not the best MU but also not the worst MU. The challenge here is that strategic Mario players almost always try and force an approach using fireballs rendering it more difficult to manually charge Limit so just keep that in mind.

is a pretty safe MU. If you have a strategy for racking up damage on him, getting a KO shouldn't be too hard since he is very light and easy to launch far. Like all characters going up against Mewtwo, just be carful when you're up in his face. He usually tries to brush off pressure with N-airs.

can heal off of Cloud's N-speical so don't spam it (I almost never use it other than in situations where he may not see it coming). Stay centered as much as possible on stage. Lucus has pretty devistating edge-guard potential considering his D-smash is a great tool for landing more consistent 2-frame punishes and it is even worse for Cloud since he has no ledge sweet spot. Create situations for him to go for a grab and then punish accordingly.

is not too hard. He needs to camp in order to have any sort of effective play so do the same and charge your Limit and if he tries to approach, go into defensive mode (against frisbees, shooters, and cans). Once you get him in the air, pay attention to his movement so you can maintain stage control. His recovery is also slow and predictable so use that to your advantage. Just watch out for frisbees when he is trying to land. Duck Hunt players love to throw those things out as they are trying to land in order to avoid more juggling.
Finally,

in my opinion is by far the toughest MU out of them all for

. Try your best to get rid of Luma first if you can. Like

, try and stay centered and play patiently. If she tries to use Luma as an approach, get that pest out of your sight and play on the defensive in case Rosalina tries to punish with an attack or a grab during the cool down of whatever you use to get rid of Luma. Camp on the edge, charge your Limit meter, and
keep it. DO NOT use your limit meter for anything else other than
recovery. Rosalina is very light and easy to KO similar to Mewtwo so there is no reason to use your Limit on anything else other than recovery. Rosa's edge guarding against Cloud is very dangerous so for that reason, keep your Limit for recovery usage.
