Take notes, aMSa.
This one in particular would hold merit if people actually knew how to use Rosy lol. Get that Luma away from her to follow up properly, a la PM Ice Climbers. While we're on the topic of Rosalina, even if throws ARE useless for comboing when done by other characters, I can guarantee that they'll get mileage from her.
This definitely connects before Mac's smoke even goes away. I'd like to say that it does before the smoke finished generating, but there's no way to tell that if that's the case since Mac got hit, obviously.
This doesn't look as solid as the above, if Coney jumped earlier and Uair'd again or even Nair'd it probably would have worked, but that Dair is too slow man.
Similar deal to the first Luigi GIF, but this time I can't tell if the smoke is still there or not, even when slowed down. Either way, I've seen Sonic do this same combo against ZSS at a lower percent so I'd say he's fine. Sonic can follow up anything because he's THE FASTEST THING ALIVE, YO!
But despite how much I advocate combos in Smash 4, buffered air dodges are still a thing and it's disgusting. My hope dies every time it increases I swear. That said this IS Bowser so if Mario did that to say, another Mario, he might have been able to follow up. Only time will tell.
