I mean this respectfully, but you're way off.. We can't know for sure, but it probably goes like this: Lucifer, Michael, Gabriel, Jesse Turner, and possibly the boss Leviathan. Also, the Horsemen shouldn't be included.. They only way they could possibly die is if their natures no longer existed in the world, and couldn't possibly be killed by the Colt.
