The standard antipaladin is CE, while the Tyrant is LE. Is there a NE version?
The Insinuator antipaladin can by any evil alignment, and is one of my favorite archetypes for any class- not because of power, but because of the flavor. It's just the most petty, opportunistic class possible. They get self-healing (with mercies!) and bonus combat/skill feats, and the ability to smite any creature at the expense of dealing only half their level per hit, rather than 100%. Their choice of outsider patron for the day affects their class abilities to varying degrees.
