Napoleon -
Legendary Creature
~ can’t be exiled.
3/2

Funny, I was just thinking about this effect yesterday, and I realized it had an awkward rules corner case with cards like Rest in Peace. If Napoleon has 0 toughness, it will try to go to the graveyard, Rest in Peace will replace that with exiling it, and then nothing will happen because it can't get exiled.

Although maybe "~ can't be exiled by spells or abilities" would be enough to get around that, since in this case, it's an SBA that's trying to exile it.

That’s how Everlasting Lich works
