Mass Dominate Fan-boys , ha.
Each edition has had it's pile of core
unsupported but interesting stuff.
Maybe call them the " Tricky Casters ".
1e had Sage , Shaman , Witch Doctor , and PurelyRandomPsi.
2e had basically the entire Monster Mythology book (I'm sure there were others)
3e had the Witch, leaving it up to PF to do that
4e had the Magewright ... you know ... the thing that crafted all the world drop x-mas tree gear ?!
OK I can see how that last one would be unconvincing to most
