Scions of the storm question
Can scions of the storm be used multiple times in the same phase? I was playing a game with my Stormcast and I interpreted the rule to let me use it as many times as I want within the phase. So for example, if I had 3 units in the Celestial Realm, I thought the rule let me use the ability up to 3 times in the same movement phase, which was what I wanted to do. However, I got into a debate with my friend who I was playing against as they interpreted the rule to mean I can only pick one unit for the entire turn. Which interpretation of the rule is correct?
