This decks is specialized for Act 2. It focuses on wave clear with ammo stash tec9 and highwayman. The deck then transitions into bomber build for the last checkpoint. This is the deck I enjoyed the most playing as Karlee on act 2
If do not want to rely on bombs, you can add cards such as shredder, large caliber rounds, and combat training.
Other cards to consider with this deck is admin reload/swap speed, more accuracy to make a laser build, canned goods/ glass cannon, offensive scavenger, etc.
If you want to be able to aim, add cards such as Cold Brew Coffee and Widemouth magwell. I would remove the "move while firing" and add some movement cards to your liking.
