This is pretty pushed, but I like the idea. What inspired you to give it reach? White does have access to reach, on a rare occasion, so it's not a break.

Hexproof and Indestructible are a dastardly and generally disliked combination, since it makes the creature so incredibly difficult to deal with outside of mass exile or sacrifice effects. Also, recall that white doesn't generally have access to hexproof on permanents.

I'm not quite sure what you mean by "cannot die this turn." I don't think it does what you want it to do. I would suggest just granting indestructible.
