Link is one of the most dangerous Smash characters.  That sword of his is about as big as his entire body.  Watch out for the flying crotch sword attack, where he tries to land on you with his sword pointed down.  Dangerous A attacks as well as a suitable combo of throwable B attacks. Link isn't to be fooled with.  Try not to get thrown off the edge.  If you do, your odds of surviving are slim.
