Harpoon no longer has a Cooldown, but no longer Slows enemies hit.
Generate 1-5 Ammo for each enemy hit by Harpoon.
Heal for 80-400 for each enemy hit with Harpoon.
Generate 1-5 Ammo for each enemy hit by Broadside.
Gain a 150-750-Health Shield after dropping to or below 50% Health.
Heal for 100-500 after exiting a Shortcut.
With this deck everytime you hit an enemy with broadside you gain 3 ammo, so you can infinit shoot. You also get healed and recuperate ammo everytime you hit an enemy with harpoon, so, for example, if there's a Maeve who comes to kill you because you're annoyiing too much you can fight her. For this you have a 450HP shield if you drop at or below 50% health, so it will be more difficult to kill you. Finally if you are getting too much damage you can quickly scape trouhg a shortcurt and heal yourself for 300HP.
Objects: (well this depends a lot of your playstyle)
