Guardian Revival

Adam Warlock has a one-of-a-kind passive ability with his Regenerative Cocoon. It allows him to move his soul around after dying to choose a place to respawn directly to. His Guardian Revival Team-Up allows him to share this ability with both Mantis and Star-Lord.
Having a self-revive is an incredibly useful option to help you return to the fight quicker. Like Adam Warlock’s version, the one caveat is that everyone can see you in soul form. Try to be discreet with where you return to so you’re not immediately eliminated again.
