So, personally I don't only use Bombslides for movement, even though it's really good for getting out in a jam. So I'm gonna list some cool combos, but no % because it varies a lot and I really can't be bothered.
First we have Links Bombslide -> Grab. A pretty good one but only at early %, either they get hit by the bomb and the grab becomes true or they shield the bomb at when you grab them because they are unsure on what to do, but if they are prepared for it... well you can probably imagine how free of a punish it is.
Next up we have Bombslide -> Usmash/Utilt. Good for building % and thanks to the large amount of hitstun the bomb deals you usually don't have to blind guess if you hit or not. Also, if you manage to get reverse Utilt instead of a normal one you can at some % get a true ish Uair.
Bombslide -> Fsmash/Ftilt. In my opinion not the best one, though you can get more damage out of a Fsmash then a Usmash it's most of the time better going for the Usmash as at least you know that one will probably hit all hits while Fsmash may only hit the 1st hit... and Ftilt just sends them away, not really worth.
Bombslide -> RAR Bair. Doesn't sound so good at first untill you realize that it can be comboed into a 2nd bair and sometimes UpB, even after the 2nd bair. It also works at a lot of varying % which is nice. I've gotten Dthrow Bombslide -> RAR Bair -> UpB at around 85% before with it being true, but I have no idea how to do that consistently. Oh yeah, it took their stock.
Bombslide -> Fair. My absolute favorite, after you've dealt a little bit of % it's true and still allows you to hit both hits of Fair a lot of times, and it stays true for a LONG time. It's an incredibly easy way to kill, If the bomb hits at late%... they're probably dead if you're close ish to ledge.
Bombslide -> Uair basically the only time when you should use this IMO is if you know that Fair will only hit the first hitbox to deal 3 extra %. Or Fair is unable to kill which happens at later % when the bomb sends them to high up or if they are at middle stage.
Bombslide -> Nair, Its a thing I guess, good knock back if you get the sweetspot but I most of the time so no reason to go for it.
Bombslide -> Dair. EVIL, if you can read someone getting up from ledge at around 40%+... it's over they are dead GG see ya. They will be spiked hard, and also this stays true for a long time though you may have to double jump at some point at which... just go for the fair, or Uair. C'mon.
Bombslide -> UpB, you get some nice% and usually sends them of stage... usually, sometimes you get the back swing which means they get center stage. Unless you were the one near ledge which in that case, you get center stage... YAAY
And then we have Bombslide -> Arrow/Boomerang/Zair. if you aren't able to reach them then this is ok for some nice %. No reason to let a Bombslide go to waste even if it's anti climatic.
Probably forgot some or left some incorrect information about some but that's life, and I hope someone can correct me on it
So yeah, Bombslides are really really good. Another thing that is good with them is that they to some extent is removing the option for the opponent to jump out of shield and grab the bomb because you're already up in their face and that would be an easy punish.
Edit: I forgot about Bombslide -> Dash attack. It has good damage and because it also has a hitbox during the over head swing it works for a respectable amount of %. But the same as Ftilt where it just pushed the opponent away.
Edit: Thank you to the one who removed accidental quote <3

On another subject, I'm dumb and just now realized that Link has a super easy kill setup which can be safe if spaced correctly... It's Landing Zair -> UpB If they shield the Zair, well they shielded the Zair, good job (applause). And if they didn't shield the Zair then the UpB is true. I'm sure you can also get Dsmash as it is 1 frame faster the UpB... but meh. Also, if you're close you can get Usmash but at that point you ave to be so close that they would be able to shield grab you which beats the point.
