Each Soul Card has a set amount of LP. Typically, Soul Cards with stronger effects have less LP. LP is not tied to level in any way, it's entirely dependant on what cards you decide to set as your Soul Cards. Also, Soul Cards will activate their effect when all of the LP it contains has been lost, and they lose LP in a certain order (Which you likely have already figured out)
