Specials
Neutral: Fire Rod
Quickly waves the Fire Rod and shoots a little fireball toward the ground, which erupts into a pillar of flames that moves toward the enemy. Basically, it's like Pikachu's or Ice Climbers' neutral-B in that it hugs the ground so you can't crouch to avoid it. It's a tall pillar, so it has the most vertical range of this kind of attack. It's meant to replicate its utility in A Link Between Worlds. If the little fireball hits the opponent instead of the pillar, it erupts for a brief second dealing vertical knockback.
*side note: I chose the Fire Rod and not the Ice Rod because the Fire Rod was in 2 of his games (A Link to the Past and Link's Awakening, the latter under the name "Magic Rod"), while the Ice Rod was only in A Link to the Past.
Side: Pegasus Boots
Basically Wario's Shoulder Bash, but goes much faster and farther, deals less damage and knockback, and the hitbox is located on Link's outstretched sword rather than the whole front of his body. Like Wario, it gets stronger the farther you get when you connect with a hit. It works the same way in the air, but with gravity. It makes you go into special fall.
Down: Spin Attack
Works much differently than the other Links' Spin Attacks. Its duration is about a quarter as long, it has half the range, and it's visually a single spin instead of multiple. On the ground it's a panic move for getting somebody that's up in your face away from you--it deals little but fixed horizontal knockback. Then, Link holds up his shield to reflect projectiles, unlike the other Links who simply block them.
Have you put it together yet? I've turned the spin attack into a shine
It's only a rudimentary one, though, to compensate for it's bigger range, so you can't jump-cancel it or use it to stall your fall. In the air, it's the only downwards angled Spin Attack (Twilight Link aims his up while Toon Link aims horizontally) before going into shield mode, and it acts as a spike if used up close at the base of the blade. Otherwise it's just a meteor smash.
Up: Roc's Cape
I was originally going to make this a glide, but I decided against it since Pegasus Boots already give you horizontal recovery. Instead, it works like 2 extra jumps. The first jump has Link spin; it goes the highest and he holds his sword slightly out during it, like Meta Knight's N-Air but with vertical recovery. The second jump has Link spread his body out; this gives him an extra vertical boost via a tiny hop the jump makes. The second jump also changes the momentum from vertical to horizontal, but only for a brief moment before Link puts his body down. Another thing: Link doesn't go into special fall during any of this so he can still act out of it with aerials and specials.
Normals
Jab: a simple one-two sword swipe. Basically Marth's jab but with more horizontal reach and less vertical range. The jab is supposed to reference his games' sword always covering a wide area so it made sense to base it off Marth in this instance.
Dash Attack: Past Link hops while kicking forward with the Pegasus Boots. The same as, say, Zero Suit Samus' dash attack.
F-Tilt: Leans forward while stabbing. Similar to Roy's f-tilt but it comes out quicker and has a lingering hitbox.
D-Tilt: same as Toon Link's d-tilt, but with a fire effect instead of an electric one.
U-Tilt: does a sword swipe above him. Good for juggling.
F-Smash: Past Link does a powerful swing with his sword that has great horizontal reach. Like ZSS' f-smash, it reaches behind him, too.
D-Smash: Past Link drives his sword into the ground. The hitbox covering the sword is very powerful, so this is Past Link's strongest smash. You can interrupt the sword planting if you're quick enough, though.
U-Smash: Toon Link's old u-smash, a single upward strike. Like Past Link's f-smash though, it covers a little more range to the left and right. It's also punishable, with a little more endlag
Aerials
N-Air: a sex kick with the Pegasus Boots. Pretty much the same as Twilight Link's, except with cooler footwear.
F-Air: a sword swipe like Toon Link's but it sends at a diagonally upward angle. Awesome combo starter if SHFFLed.
B-Air: a backwards sword strike. Good for edgeguarding, it works like Meta Knight's b-air but has more range and less knockback.
D-Air: Toon Link's old d-air
U-Air: Past Link stabs the sky like the other Links, only much quicker.
Grabs
All of his grabs use his Bug Catching Net from A Link to the Past, though he uses it in a similar way to the Villager's net grab from Smash For (a grab that covered both behind and in front of you like the Bug Catching Net did in ALttP would be really scary). This means he can grab people even if they're not on the ground. This is to keep the theme of every Link having a more utility grab than most other characters.
Pummel: The fastest in the game, like vBrawl Lucas'. Basically he kicks the grabbed opponent with the Pegasus Boots. You can hit a maximum of 8 times if the opponent makes the mistake of not struggling. Realistically, You'd only be able to get in about 5 kicks at most if the other player button mashes his / herself out of the grab.
F-Throw: Past Link picks his opponent up with the Titan Mitts and throws them at a fixed angle forward. This throw doesn't really allow for DI so it's rather strong.
B-Throw: Past Link turns around with the opponent and stabs them away. Like Toon Link's b-throw, it has fixed knockback.
D-Throw: Past Link sets the opponent down and slams his sword into them. Sends at a vertical angle and is quicker than it sounds.
U-Throw: Tosses the opponent up and does a swipe above him. This has a lot of vertical knockback.
Taunts
1) Takes out the Magic Mirror to look at it.
2) Takes out an ocarina-looking flute like in A Link to the Past and Link's Awakening. If regularly pressed, you hear the flute song like in A Link to the Past.

(this version is the long version. The 4 second version is what I mean)
If you light-press it, you get the Ballad of the Wind Fish instead.

(you hear it about 8 seconds in. Basically, the short version again.)
3) Does a quick spin and raises his sword in the air like when he beats a dungeon in A Link to the Past.
