National summon as a god?

[Olm]

I've been missing Trees as pretenders ever since.
An immobile Treelord pretender with Nature and a bit Earth, generating a not so small amount of Nature Gems per turn would be super thematic for Man and also usable for TNN, Eriu, Pan and all other Nature nations. There is even Yggdrasil as mythological source for this. (Getting in Norns also would be cool in this case).

Treeants would also be a great choice as pretender chassis and even Ivy Lords could do.

Plants are underrepresented anyways. What about a giant subconscious fungus as pretender? (For the biology geeks: I know fungi are no plants....)
Or a giant Bloodvine.
Or something strange like a field of Orchids or the like.
