Black Widow - Always prepared

Black Widow with Shield subtheme + One way or Another package + prep cards. Designed for solo play. Wins very slowly because of minimum damage, but the villain will never get to do anything.

Other cards I've tried: Venom (ally) - really fun win the combo happens (revealing a bunch of encounters), but by that point you've already won the game most likely. Slow and risky when you aren't set up. Under Surveillance - very good card in solo, but this deck has never needed it.
