I love that you made Garrus a weapons team. (I'm not bias, He is only a regular in every shore-party.)I think you have a lot of options with the biotic users, Samara, Jack and Kaidan could do some interesting manipulation to their host ship.
Jack could grant a single reroll on your first attack that activation, maybe even suffer a shield damage due to her destructive nature?Where as Semara could assume a more defense process like returning a defense token to green at the cost of a discard. Kaidan you can take to Virmire where he may or may not die protecting a bomb
