idk if ur doing final smashes, but we really need Link to go into Fierce Diety mode, and just be all powerful. i kno ur making everyone great, but this final smash needs to be epic. Have the invincibility of super sonic with the speed of super Wario man and the power of Giga Bowser, combined with all of Link's awesomeness, and he really needs to be the most badass final smash u can make. just throwing that out there.
But if you really wanna buff link, use Light Arrows (super powered), give him super bombs (remember a Link to the Past), mirror shield, but all you have to do is duck, and it reflects all those energy attacks, moving up-b (like wind waker). and instead of the boomerang, how about the Deku leaf? It could be used like mario's cape, can still do the wind thing, and would be great for recovery.
