i am assuming that only revifify and true resurrection to bring a reborn ua race back from the dead, i am making a reborn zealot barbarian and want to know how that would work

If you are using the UA version then they are both Humanoid and Construct or Undead. Either way they are part humanoid so any spell that can bring back a humanoid would work. 

Edit: the rules in the UA state that if it effects at least one of the creature types it works. 

Thanks for the clarification this helps a lot

The final print version did drop that, probably because undead can be turned or dominated by more than a few classes and monsters.
