Well my reasoning is that the card mind control specifies action phases. There is the quickcast phase and the action phase, and then they are part of the same action stage. But i don't consider the quickcast phase an action phase because.. well they are specified as different. I always waited to use it after someone got an action, but I'm waiting to see if there is a small gap before the first action is taken. I feel there shouldn't be, as the normal timing is at the end of a phase, and the end of the quickcast phase is still not the action phase, but mind control specifies timing overrides kind of.
