I'm actually gonna say Huangdi matches Nidhogg here and probably beats him if the fight is in Huangdi's territory. I don't know what I'm going for in terms of personality restriction ( the guy is a benevolent ruler type), but it seems like Huangdi is medea tier which is really really good as a mage. His Gaia connection let's him spam phantasmal beasts like a dragon as much as he wants of course with the problem of him only being able to have one phantasmal beast.

On a side note, Eastern Dragons are capable of destroying the entire world in a rampage, but thankfully the grail can't summon them.

You underestimate what a Gaia connection does. Its literally a hotline to Gaia itself like that which nature spirits possess. Gaia essentially gives you just enough power to outmatch your opponent as well as effectively constantly replenishing magical energy. It's an extremely powerful skill to have(you should list this as a skill and not a noble phantasm btw).
