Can you revive without a Reboot Card?

Excuse me, I'm curious about something. I've heard about this "Reboot Card" that's supposed to revive players in certain games, but what if you don't have one? Is it possible to come back to life without it? I mean, is there any other way to recover from a defeat or setback in the game world without relying on this specific item? I'd appreciate your insights on this matter.
