GOD!, I'm fine with you trolling but please don't try to mislead people with inaccurate information. fox's vs. space animal chaingrab works until 50% with no DI, and if the opponent DI's to the side each time you can literally chaingrab until death (chaingrab to 90%, pummel, uthrow running usmash).
ALSO, utilt combos into another utilt until about 75%. try it in training mode. uthrow utilt an opponent that doesn't DI and try to continue utilting them. utilt will combo into itself until about 75%. then you can bair or something and boom they're nearly at 90%, with a chance for an edgeguard (50-50 if you set it up right). if you find a way to work a soft bair in there, you can even do soft bair into usmash or dash attack, or soft bair into fsmash sometimes. utilt into dsmash combos sometimes too, silent wolf had this weird dsmash phase where he would get dsmash out of the most random situations as a combo finisher and it ***** lol
edit:
uthrow triple usmash is pretty good on FD (you have to techchase for the 2nd usmash, but usmash comes out in 7 frames - as fast as a grab - so it's very doable on reaction), but the problem is that after the third usmash the combo is usually over with no chance of followup. plus, you get less damage than a chaingrab.
also, if they DI the chaingrab to the ledge, you can mix it up with uthrow dsmash, uthrow shine (off the stage), bthrow gimp or whatever (fits the theme of lucky "wanting him to get off the stage as soon as possible"), and even dthrow off the ledge lol. there's a bunch of mixup options that are all pretty hard to react to, so you might as well chaingrab. most opponents don't DI to the ledge anyway haha
