Does Shadowform deactivate every time we die?

I want to have to remember to reactivate something that should be a passive ability every time my character dies. I hope that is something priests can help with. I don’t like being able to see any transmog I make. I want to look like a purplish cloud all the time. I heard there is a priest spec that can make this happen.

You can easily macro an if condition into most of your spells that just checks if you’re in shadowform and if not puts you in it.

/cast [noform:1] shadowform
/cast mind blast

Should work as an example.
