Gaming is for having fun. Fun requires clear rules.
During each of your following turns (that is, each time it would have been your turn if you were still in the game) you temporarily re-enter the game as a “shadow-gunslinger”— a “shadow-Deputy,” “shadow-Outlaw,”
or “shadow-Renegade,” respectively.
As a shadow-gunslinger, you have zero life points. You draw 2 cards, play your turn as normal, and then leave the game again. During your turn, you play as if you were still alive, with all your abilities. But, you cannot gain or lose life points (you ignore the effects of any cards of this type). At the end of your turn, you exit the game again, and must discard all of your cards in hand and in play (including any equipment cards you bought that turn).
I suggest to read the whole GAME VARIANT: SHADOW-GUNSLINGERS part once again, as you may be missing more
