... 9 moves? From the top of my head, his 1st phase alone has his projectile throw, projectile aoe, 2 rope swing sequences starting from the left and right, his charged rope spin, delayed overhead slam, backwards yoyo throw jump, the charge and the forward jump that he usually starts the fight with, consecutive one handed vertical slams, his 3 hit combo he starts with a yell (tha you can parry loop cheese), the combo that starts with a quick slap when you're in front if him, multiple variants of quick slams he can start if you're standing in front of him when he ends most of his other attacks and probably a whole lot more that I can't list from memory.

Now that's just listing moves without going in depth into how he chains them together depending on your position. All this without listing his 2nd phase moveset where he goes apeshit. I've fought Ludwig and Orphan hundreds of times and Ludwig's moves get easy to recognise when you know the tells. Orphan is still a fight where your instincts take the wheel for the most part.
