Questions regarding YOD HEH VAU HEH

So i have used various different systems over the years, and also been on occult hiatus for a long time as well sadly but want to come back with full force.

Anyways how do you guys feel about systems that utilize YHVH? I truly do feel he's the demiurge and it probably is not good to trust him.

I have heard new avatar power is a very fast, and powerful system for getting whatever you want though. And it's main focus is YHVH.

Should i entertain it, or just focus on bardon and shaivism instead?
