If you had told me like a month ago that Naturia would be one of the coolest and best decks in 2022 I would've laughed at you. Now I've beed Naturia-pilled.
Camellia, Molecricket, Spring Breeze and Sacred Tree form the backbone of an extremely powerful yet unsassuming recursive strategies with the help of Vernalizers. You need to setup so Molecricket is in your GY, then you summon Camellia to dumps Sacred Tree from the deck which searches Spring Breeze, then you revive Molecricket and use it's effect to summon from deck Sunflower. This means your board consists of a repeatable monster negate (Sunflower thanks to Camellia's cost substitution effect), Molecricket can summon Horneedle to destroy anything your opponent special summons and even if you need monster to tribute, Molecricket revives itself to cover the cost. This is just the bare minimum of what the deck does, tho'. Now let's talk about Vernalizers...
Vernalizers pitch any monster from your hand along with themselves to use a specific effect and all revive any earth monster with the only condittion being getting locked into earth monster effects (but not summons, remember that). Essentialy ara a roundabout and costly way to summon monsters from your hand and deck. Forest is the best starter, since it's unique effect is foolish burial for any earth monsters but it won't be revived by its second effect. This translates to Foolish Burial King Regulus so you can revive it with your other Vernalizers. Hills searches any Vernalizer card, mostly the trap, which bounces any number of your opponent's cards as long as you can also bounce earth monsters (this also translates to the possibility of bouncing a Maxx "C" you summoned from the GY, but since this a TCG focused list we don't have to worry about that, sorry OCG). Finally, Seedlings adds you any earth fairy monster which means any of the other two Vernalizers. Since both, at the very least, set up your GY you still play them at three. I decided to play Mountains because it unbricks your hands full of Vernalizers, but it can be cut. Now, the real star of the Vernalizers is Vera. She is a Crackdown, Splight Elf and a monster negate (if you have 5 earth monsters on the field, which isn't uncommon) in one. She revives King Regulus during each of your opponent's turns. She is the second pillar of the deck (along with Camellia).
One extra note: remember how I mentioned that you're only locked into earth monster effects? This means that you can still summon Zeus or Baronne since you'll be using their effects during your opponent's turn anyway.
