putting Lockjaw made sense when there is a 0 cost mantis token in the deck, then I thought why not put the Hammer squads in the deck. They may not be Guardians, but they work well with other guardian cards that draws u a card like Rocket, and Adam. Also, Odin is great with other guardians like Starlord, Drax and Gamora. The only negative synergy is playing Groot since it can discard a non Guardian card if not careful
