A Witch of Heart would be interesting.
Heart Heroes would be either socially dominating yet emotionally withdrawn, or emotionally in touch but easily influenced.
Witches would, evidently, be rather worrying people who have trouble with trust, combined with someone who likes making plans and taking risks.
So, lots of internal strength and energy + emotional manipulation abilities + internal dynamism and plotting = ???
