Amazing defense team due to its ability to dodge attacks. May be the most used team in the game. Every player in the game should have a strong artist team because many players don't have the knowledge or team to take it down. You can substitute Flamenco Prissy or Penelope Couture if you can't get Tazinsky.

Nemesis - Pirates, Scoundrels 

The Dunker teams is overpowered in early to mid-level play. Lebron can destroy most teams by himself once he gets the ball. On defense, The Dunkers are a great way to stop people from stealing your chests because of Lebrons ability to kill. 

The Magic team uses Alchemist Frankenbeans to stall teams down and waits for Egghead the Knowing to unleash and banish the enemies, no matter how strong. This is not the best team for Arena but can be used in certain situations very well. You must tune up Egghead to level 30 before he starts banishing toons. 

The Pirates are a decent team, but you want them for one reason and one reason only, the destroy the Artist team like no other team can. Since you will run into an Artist team almost every time you do an arena, this is a must have team. Cannoneer Canasta can fill your team, but you will  want Dread Pirate Penelope as soon as you can get her. You can get a lot of the toons from participating in the Alliance Wars.

Nemesis - 

May be the best overall team. Some players like to use strong defensive teams, the Imperials will cut them down fast. This team has a lot of offensive firepower and great survivability. Foghorn's ability to knock down shields brings the Heroes to their knees.

The Divines have the capability of defeating teams way above their level due to their resurrecting abilities. They are bad on defense or auto-mode because Anubis has a tendency of sacrificing allies at the wrong time.  

This team is really good for pushing your campaign. When Monster Tweety gets to higher levels he is very formidable. 

This is another all-around really good team. Bugs provides good tanking and Marvin will destroy teams. 

Masterminds are a great anti 3-star team. A strong Star-Pharaoh Marvin can wipe out any single toon preventing your opponent from getting 3 stars from you and stealing your chest. The team is a great overall team and many players suggest to aim for this team as one of your first. This team also does very well against a dodge team.

This is a decent team, but their true power lies in their ability to knock off the Artist team. This is the second best choice to kill the Artists.

The Villain team is a great quest clearer. They will wipe through quests super fast with their AoE damage. At higher levels they are a force to be reckoned with. Nova Bunny is a huge damage dealer and is one of the best healers in the game. 

This team is very annoying to go against and can slow down attacks causing a lower score in the Arena. 

Boxers are a very strong offensive team. Hippity Hopper can wipe out entire teams once he is fully buffed.

I don't really play this team a lot. I will post more information when I get it.
