Super Smash Bros: Battle Techniques

When an opponent rolls, position your character next to where they will be. Then, attack. They can't do anything to stop you when in a roll.

When an opponent uses shield frequently, attacks may be hard to land. However, grabbing and throwing them is still effective.

Get used to using different attacks, so you can defeat opponents with a variety of different play styles. Also, using one attack repeatedly lowers the attack's strength.

Have one main character, that suits your play style. I usually use Pikachu, because he is fast and agile.
