Recommended team:
Use the following trick to make a hard to kill team. Make a team consisting of Wolverine, Blade, Ghost Rider, and Luke Cage the Bad To the Bone team. The team bonus will be that 5 of all damage will regained as health. Also, all these characters have a way to regenerate health. Equip he following outfits. For Wolverine, Astonishing, Max Out Health Regen and Defense. For Blade, Ultimate, Max Out Health Regen and Defense. For Luke Cage, New Avengers, Max out Health Regen and Defense. For Ghost Rider, Original, Max out Resurrect Ally and Defense. It is also recommended that Ghost Rider be equipped with The Heart of Mephisto 10 of attack damage turned into health or a similar item because he is the only character without a Health Regen. Equip other characters with gear that increases defense or dodging capabilities. Not only will your team be difficult to hurt, but they will be absorbing and regenerating most of the damage they take. If a teammate dies, Ghost Rider will have a 50 chance of resurrecting them. Note that Ghost Rider is the weak point. He does not regenerate, and if he dies resurrection is lost. Also, Wolverine will regenerate the fastest because he has an inherit ability to regenerate in addition to the suit's bonus.

For easy money, health, energy, Extreme Momentum Orbs, and experience for leveling. make a team consisting of Luke Cage, Elektra, and Dr.Strange. When they each have a full Momentum bar, get a group of enemies around you. Then, use the power. Elektra will stun all enemies with her Curse of the Hand. Then Dr. Strange uses his Mystic Maelstrom to kill all stunned enemies, causing them to drop Extreme Momentum Orbs for each enemy killed. Then, Luke Cage uses his Sweet Christmas to kill any of the remaining enemies, giving you 472 more money for each enemy killed in the attack sequence. This trick is especially useful for leveling characters, unlocking costumes, and maxing out stats. The best place to do this is in the Shield training simulator on the Thunderball mission. Even if you run out of time you will still get the levels and money; do not worry about killing the Boss. Just get your momentum on Luke Cage, Dr. Strange, and Elektra
