So I tried, to see what I came up with even though this still needs a LOT of tweaking as opposed to just randomly throw 4 of every card that looks good, and although you initially wanted to focus on Crosstown Courier with Tricks of the Trade and Trepanation Blade , it is probably easier to go the Defender route.
