I guess when Time 7 is destroyed, The situation occurs like this.The first phase of turn is Given by Chrono engine. When you get first phase when your chrono is alive, and You kill it with anything.Then the second phase of your turn is the one that is normal turn, Not induced by Chrono at all.The first move is additional with chrono.This is possible solution for this question.Also, Read its description. It says You can use additional card each turn. And that additional turn is first phase, Then no matter what you do with chrono, You will get your normal turn too.
