One of my favorite mechanics comes from Cinematic Unisystem. To return from the dead, the player must spend Drama Points (sub action dice or hero points or similar mechanic). The number spent depends on when they come back, not how. IIRC, if they don't return until next season (after the current plot arc) its one point. Several games away is 3, next game is 5 and right away is 8. I could be wrong on the numbers, but that's the idea. If you don't have enough, you can owe that many, giving any you earn back up to pay the debt.
The how is entirely up to the player. They come up with some explanation as to why the character is returned. Perhaps they were made into an undead and have recieved their free will back. Or a higher being decides they have a purpose and returns them. Or a mad scientist uses their brain for his Frankenstein monster. Or there was a miracle in the ER.
