Link is a very powerful character who's melee attacks are definitely the highlight of his arsenal. Using his button attacks are a very wise idea as he can do tremendous amounts of damage with them.

[edit] Special Moves

Button(s)	Attack	Explanation
	Boomerang	Link throws a projectile that returns to him, so it can damage an opponent twice in one throw.
+	Spin Attack	Link performs a circular attack with his sword. You can use it to propel yourself upward when in mid-air.
+	Bomb	Link pulls out a bomb to throw. Usually does between 5-10% damage and leaves opponent temporarily stunned.

+ Link does a 3 move combo hit that if your opponent is on you or right next to you will hit them 3 times with the last hit sending them to the air.
