If after Nacht Jager (236A) you notice the Ragna ID's on reaction to your wolf transforms, do 7D and cancel it (you know, with C), he will whiff and you can score a 5C CH into Nacht Rozen
Edit: It seems you may be able to get a CH Schwarz Jagd (236B) and that's a world of pain, even without meter (like 5k)
If he IBs (or hell, if it hits) and you KNOW he's gonna ID a delayed 4D will beat it
