I don't know how many of its other mudras are affected, only the real high potency one. I think he said he hit for 1900 with that move when affected by Foe.
All ninjutsu (not mudra, btw, the mudra refer to the individual symbols that compose a ninjutsu) except Fuma Shuriken are magic. To verify this, you can go against levi EX and see which ones that tail reflects.
Raiton, Katon, Hyoton, and Suiton are all magic, and thus affected by Foe's and anything that limits magic. This makes DPSing fights like Levi very, very tricky.
