Counter Tips

You need to capitalize on the fact that Young Link needs very specific confirms to kill. Things like fair or up b very close to the blast zone, or a f-smash call out. If you avoid these you're fine.

You won't win the projectile war unless you have a fully charged neutral B. This is because his fire arrows will cancel your missiles. This is why you shouldn't approach this way.

Young Link bombs will cancel any charge of neutral B, so make sure you shoot where you won't collide with them.

If you expect a landing dair, call out with an up b out of shield.

With a certain timing, your up air will actually win a trade against a Young Link dair.

If you can predict when a bomb Young Link pulled out will explode(it's 4 seconds) then you can use this to your advantage. For instance, grab and throw right before, and then attk after the explosion.

Heat seeking missiles can be good as an edge guard, as sometimes Young Link has no option other than travel in the direction of the missile. If this happens you can attack while he's in hit stun.
