Kinomoto Sakura-chan wins any fight of course, if she has Sakura Cards. It's simple: The Time !! The Erase !!
Or she could just make him into a clow card. The Mecha-Hitler !!

If it was beginner Kinomoto Sakura, it becomes a hard fight. I think her skating evade abilities are extremely top tier, but Mecha-Hitler's rapid fire would be hard to outskate, even with her wall-riding abilities. But I still think Sakura would win. Hitler would be dazzled by her beauty and unable to shoot such a cute thing. So, it's not possible to win against her even if she is beginner mode and you are stronger.
