Mantis - party healer

Hope to get Mantis up as soon as possible and use to get other players healed. Leadership cards to give her more health and ready for several activations per turn. Groot and Rocket included as they are just great allies and help deal with minions.

Can also be used to keep Drax healthy in hero mode. He will be more squishy than in Protection, but I wanted to try to build a non-green deck for him.
