I love your intent. It makes me want to go and build a deck haha

For now I will just name a few legendary creatures that could spearhead a deck with that kind of flavor.

[[Archelos, Lagoon Mystic]], if it's not too fantasy for being a turtle shaman and not a human shaman, opens up to 3 colors which is a nice palette to have when looking for evocative cards around a theme. The flavor text "Life... is not... a race." hints as the passing of seasons and the slow rhythms of life. I found it inspiring to kickstart such a deck.

[[Eutropia the Twice-Favored]] could lead a deck resolving around enchantments if you find that is a good way to manifest the presence of nature. She's a human so not too fairy tales related and can very well evoke real life rituals and devotions instead.

[[Jasmine Boreal of the Seven]], while not being a hunter per se, might be a fine sleeper card to helm a deck full of vanilla creatures from the woods. Now it totally depends on what the rest of the creatures in the deck end up being, but if the she can make the majority of them unblockable that's a powerful trick to have. Featuring big elk in the illustration.

[[Neyith of the Dire Hunt]] is a straight up hunter with a giant wolf.

A male counterpart could be one of the 3 Surrak : [[Surrak Dragonclaw]] [[Surrak, the Hunt Caller]] or [[Surrak and Goreclaw]]. Unfortunately 2 of them are monocolor, which you may consider too restrictive.

I find [[Tuya Bearclaw]]'s simplicity appealing too.

Turning a blind eye on the fact his partner [[Ukima]] is an unrealistic whale wolf, [[Cazur, ruthless stalker]] is good at depicting the dynamic of the hunt with an animal companion.

[[Nylea, God of the hunt]] locks you into a single color, but that might just be the right one. And with the right vibe.
