Things I've noticed:
-Dair uses the same animation. A downward thrust the same as the other two Links. No confirmation yet on the fire sweetspot
-Neutral Special is still fire bow, and the fire gfx seem to be more pronounced while charging.
-Up Special in the air uses the same animation, still shared with Link prime and presumably Toon Link. No idea if the grounded version is still a multi-hit move.
-Fsmash is still the same animation as Link's (but not Toon Link anymore), looks closer to Brawl/Smash4 than the original Melee animation. Still a two-hit move.
-Usmash is still the same animation as Link's, still a three-hit move.
-Grab is still the classic hookshot tether, shared by Toon Link but no longer shared by Link prime. Presumably still has a Zair as well.
-Uthrow is the same animation, presumably still shared with Toon Link (but not Link anymore).
