I found that the best permafrost synergy is this 
because permafrost is frozen soil, the combo works, and the color scheme is on fleek.
Permafrost has a very Earthen feel to it, so I feel like the Sage Ice and a very dark colour of Water (Abyssal) gives it the underground natural feel that one would get from this image.
Also Wind literally cannot enter the ground whereas Water can, in fact that’s how Permafrost forms.
For sea storm Abyssal Water fits more than default and Neutral Wind 
fits more than Cold since sea storms are generally dark and edgy.
I honestly called this one Fossilized Wood since Petrified Wood is a common concept people are familiar with, but this also works with Wildfires too since Wildfires release a lot of Ash.
I was boutta say that Lightning doesn’t fit with Sandstorms too much but HOLY this looks cool
Go Blaze as a Primordial if you do this.
