Figure I'd throw in my ideal BotW link moveset (Toon Link staying the same in order to preserve classic link gameplay).
I'd focus him around having as many runes and champion abilities from the game as makes sense, but not pushing to have all of them.
A moves (only listing ones of note), are
Down smash: Spin attack
Up Smash: Urbosa's fury, acting like a long charge-up pikachu downb but the lightning bolt travels instantly.
Side tilt: Shield bash, which reflects projectiles and causes the enemy to go into an unusually high amount of hit lag if you clash with an attack.
Activated similarly to Peach's flight, he can pull out his paraglider.
His shield is daruk's protection, functioning like yoshi's egg in that it does not shrink.
Grab: Magnesis
Neutral B: Arrows. Tap to switch arrow types and hold down to charge up a shot, releasing to fire. He has infinite normal arrows, plus a limited number of fire, ice, thunder, and bomb arrows. He also has 1 ancient arrow, which kills at low percents. He can find extra arrows of special types if items are turned on. Unlike old link, he has control over the arrow's trajectory.
Side B: Master Cycle 0. Essentially it's Warriors bike.
Up B: Revali's gale. Flies up while generating a windbox that pushes other people up, and then gets to glide on his paraglider immediately after. This does not put him in free fall.
Down B: Remote bombs. Like his current bombs, but with no timer. Will only detonate upon reactivating the special, similar to snake's C4.
Final Smash: Stasis. Link freezes an enemy in front of him and can hit him as many times as he wants in the time limit. Afterwards, the knock back is combined and the enemy is sent flying.
Edit: Also, wall cling+wall climb as an option for recovery.
