Forum:Fortune Lady Dark vs Rebellion Xyz Dragon

I've once again met a Fortune Lady Dark and once again decided to go against its 4 turns of boosts with a Rebellion Xyz Dragon. I've heard from a friend more experienced than me that Rebellion Xyz's eff would manage to halve the attack of FLD even if her effect defines her atack depending on her ever increasing level.

But once again another player says it's not the case because her eff defines the attack and all. In any case, either right or wrong, I wonder what rule defines what's right from wrong in this case?
