theres no best team. Just well made teams.

Anyways, theres not THAT much difference in damage between each team. No team is gonna do AOE damage and just 100-0 another team.

You gotta be more specific in your question.

There are teams like built around Gaara that do massive damage, but may not be what you're looking for.

For starters go for Sasuke 3 stars for his mystery, which would amplify all your lightning characters' damage. The synergy from Sasuke is also great if you had Hinata or Neji. Guy also works well with Light.
