Edge-guarding is the act of attacking your opponent in any way so as to prevent them from returning to the safe ground of the stage. In Brawl, proper edge-guarding is crucial to getting kills at more reasonable percentages. The degree to which you can effectively edge-guard depends on the characters involved.One good example of edge-guard would be to use a ray gun on the opponent to keep them knocked off the stage.
One of the best and most common methods is to jump off of the stage yourself and grab the edge. When the opponent gets to your level, they won't grab the ledge and they will descend down and die. Be careful of who you use this method on, because characters like Ike will push you off the edge and you won't be able to recover.
