His primary go to would be his Shadow Magic, and what would go off first from what we have seen is his Passive Power Nullification, so he could nullify any abilities associated with the 7 schools  and shadow magic [Life, Death, Illusions, Fire, Ice, Storm, Mind, Willpower, Fear, Weather, Darkness, Power Null, multiversal levels of reality warping, Attack Reflection, Dream Manipulation, Nightmare inducement, Soul Manipulation] Ghidorah would have, which is further amplified from the fact that he can bypass resistances to beings even stronger than him.

After that he can mind hax, which is pretty hard to survive considering Shadow Magic can negate resistances to the abilities it gives.
