War Blessings

I know you get war blessing + gem bonus when you move UP to a higher league for the first time. What about in other circumstances?

Question 1: What happens when you move DOWN to a lower league? (do you get war blessings + gems)

Question 2: What happens when you then move back UP to your former league? (do you get war blessings + gems)

You get the rewards of the league your team placed, so moving down gives you less gems and less war blessings and moving back up will give more and the war blessing back.
