Pisces and its modern ruler Neptune (magnetism) have a beautiful reputation for their sacrificial goodness, kindness, and empathy.
Yet Pisces is a dual sign and through Neptune can also take on the predator role in its many forms, feeding upon the goodness etc. of others who become their victim/prey and sacrifice themselves to serve them. A harsh Neptune in charts often shows 'the sufferer' in the give or take one way or another, according to Neptune's natal sign.
I also think that Pluto has that attraction force quality that many cannot resist succumbing to, and become controlled by. Natal aspects to the personal planets and sign placements will provide infornation into how it works.
Uranus can be a good lightning attractor/conductor.
Venus and Mars are easily attracted by the physical appearance of/to others, whilst Mercury can become attracted to someone's mind. Two in my family circle married men of whom they said, 'he's no adonis to look at, yet ..............'.
