As an experienced player I only GUR and GSR only useful cards which I plan to use in the future. Other cards which could be useful in future are kept in my storage too.

For overkill your team is okay and as you said not reliant enough. This will change after you got better fitting cards. If you plan to kill FAW/LAW only without overkill the Lu Bu combi might be more reliable and would save BP and items. Which way do you want to go? Later in the game you can choose better.
