What builds can utilize the Cain's Destiny Swap

Well Barb is not a good fit.
Monk can with both Inna and SWK, you’d probably look at Exploding Palm and Tempest Rush respectively.
Witch Doctor can with Zuni.
Wizard can with Tal Rasha and Firebird’s.
Crusader there’s really only Akkhan’s.
Demon Hunter there’s Natalya’s only. You might be able to do something with Marauder’s or Shadow, but it will take a lot of power.
Necromancer has no options really.
