As irrelevant as ultimates usually are, I am not a big fan of this one. After making a million things into trees, ramping lkke crazy, or doing other shenanigans, I am rewarded with an emblem that says "Play more trees!" Thats more of my hatred for green design space though. I like animating lands. Animate lands!

The +1 feels a little too powerful for a 2 mana planeswalker, though the only real baseline for that power is Tibalt, the Fiend Cursed. Still, this seems like something that would go on a 4 mana walker - it's very similar to Kiora, the Crashing Wave's ability.

A planeswalker with the same ultimate ability was printed (Nissa, Vital Force) so I ought to change it in this one...

So... The +1 is too strong at 1G for sure. At least try GG at the minimum.

Your -X isn't worded right.

"Put them into your hand, then put all other cards revealed this way on the bottom of your library."

should be

"Put any land cards revealed this way into your hand"

Yay. More wordy. I know. You should probably change the ability entirely.

EDIT notes:

The last two loyalty abilities were

> -X: Reveal cards from the top of your library until you reveal X land cards. Put them into your hand, then put all other cards revealed this way on the bottom of your library in a random order. X can’t be 0.
> -6: You get an emblem with "Whenever a land ETBs under your control, draw a card."

I'm liking the mega-Life and the new semi-regrowth abilities. It might even be too powerful at , but your set has a slightly higher power level than most so I assume its okay.

The ultimate was modeled with Natural Affinity / Nature's Revolt in mind.

I removed creature recursion from the second ability btw (matches flavor better as well).

I don’t know how I feel about the plus being able to lignify itself. Planeswalkers that lose planeswalker unique weaknesses for the entirety of the opponents turn is unique but I don’t know if that’s entirely good.

It was the idea that that can be a trick you can do with this. However, with what little playtesting I've done with this card it seems generally better for you to either animate an untapped land you control or the problematic cards themselves rather than this to protect it. Of all permanent types, creatures are the most susceptible and have the most effects targeting them. Ie. Turning this into a creature would make it possibly to use stuff like Call of the Sea on it. The tactic would likely be most successful against mono- decks, but even then stuff like Sound of Horns would (still) wreck you.
