Ive always wanted to make a Young Link mod, so here are the moves I thought he'd have. *assume he's facing forward*
GF Sword: Great Fairy Sword
Jab: Like the Majoras Mask standard 3 hit attack, two slashes to the left and a wider one to the right.
F-Tilt: A forwards stab, like when L targeting and pressing Attack+Forward in MM. It would also be angleable.
U-Tilt: Kind of like Marth's.
D-Tilt: The crouching shield stab from MM.
U-Smash: An upwards thrust with the GF Sword.
F-Smash: He holds the GF Sword behind him while charging it, and slams it forwards from over his head, kind of like the vertical slash in MM.
D-Smash: A spin with the GF Sword low to the ground.
Dash Attack: Like Marths
N-Air: Like Captain Falcon's.
F-Air: A slash to the right, and then a higher slash to the left.
U-Air: A thrust of the GF Sword that's a little slower than Link's but stronger.
B-Air: Like Falco's.
D-Air: Same as the Upwards version, but downwards. He'd also hold it out for a little bit longer.
N-Special: Because Toon Link uses Fire arrows, I thought it'd be cool if he had Ice arrows instead they'd take a little longer to charge to max power, but would freeze foes when fully charged.
U-Special: On the ground, I thought of it being a single spin around Young Link with the GF Sword that can be charged to blue and then orange magic power, with orange being the strongest and widest. In the air, It would be two slow yet strong spins that send Young Link upwards.
F-Special: It would be like Links, but would pull opponents backwards at the max range of the boomerang, allowing it to hit twice.
D-Special: Instead of a bomb, how about a Bombchu? It wouldn't be as strong, but would be able to travel along the ground. Young Link wouldn't be able to hold it as long, being a better tool for bomb jumping.
Grabs: instead of using a regular Hookshot, he'd use the one from MM. The throws themselves are like Links
NOTE: These are just suggestions, and I don't expect someone to even consider them. However, If you want to use them, that's fine by me. I just wanted to make my contribution.
