Get yourself a shotgun and go wild.
Fast Deck with a lot of self sustain in it. Ideal to play with Evangelo to have self free, or hoffman for extra ammo capacity.
Replace last 2 cards with damage boost for end of Act 2 and extra move speed for Act 3. (not act 4 tested)
The idea is to shoot more bullets for healing, do not add a lot of damage to deck. crouch for accuracy!
