On the
trailer video YL comboed bomb into Fsmash; Link couldn't do that in SSB4 because the angle of bomb launches. I wonder how YL's bombs work; they might be incredible combo starters. He also Uthrowed into Usmash into aerial upB. I doubt the last part's a combo but Uthrow would probably lead to Nair/Uair combos at higher %s, if true.
I think YL will be a zoner with frame data close to Link's but maybe a frame faster, like how TL's jab is f6 in SSB4 vs Link's f7 jab. Having Zair is a huge boon when facing swordies like Marth. If YL keeps Link's incredible landing game (TL lacks) he could have a very streamlined chain/combo game once he gets started. Fair 1 (if it works like Link's in SSBU with no knockback)> kill move like Fsmash. Bair 1>turn around jab, etc. Nair/Zair>DA. I wonder if YL's DA is a kill move or more like TL's?
A big reason I never played TL was his floatiness. I don't like floaties. But a TL, more mobile and slightly faster, with Link's gravity (YL) could be a very good character.
