This deck's specialty is quickly swarming the field with Naturia Stag Beetle and Naturia Hydrangea, then using the skill Beatdown! to overpower your opponent. Adding tech cards to protect yourself ensures that your opponent will not destroy all your monsters while Beatdown! is inactive.
Summon Naturia Marron to activate his effect, then send 1 naturia monster to the graveyard. You can send Naturia Pineapple to the graveyard to later be used as tribute. Once per turn, return 2 naturia monsters from the grave to your deck to draw a card. It would not be recommended to return Naturia Pineapple to your deck.
Beatdown! does not boost your attack during your opponent's turn. So even the strongest monster in your deck would only be a mere 2200 attack with no way to protect himself from stronger monsters. This is why you need spell/trap cards to defend yourself.
Mirror Wall halves your opponent's attack points if they attack while it is face-up. This usually forces them to end their battle phase.
Exterio's Fang is your protection from spell and trap cards, but can only be used when you have a naturia monster on the field and it forces you to discard a card from your hand, great if you only have Naturia Pineapple on hand.

Red-eyes deck does the same thing as naturia, they get monsters out on the field fast and use the beat down skill as well as balance to Get a good hand. Before Red-eyes was nerfed they were WAY to powerful and could beat you very easy, so if you play a Red-eyes deck than don't and complain about naturia decks because you have no right.
Konami needs to fix this broke ass deck, seriously, PvP is not even fun anymore, you only see Kaibas with this shitty deck, whats the point on playing the game anymore? theres no variety only damn Naturias everywhere, no dragon, fiend, light decks, nothing, only naturias, ffs.
I'm in Plat and I haven't seen a single Naturia Deck, lots of the Phoeonix and Red Eyes though. And while I thinks its a good deck, I've lost plenty and it can be beat. Also your chances of dead hands are kind of high and if you have to wait on your cards you just give your opponent a bunch of turns to set up.
And honestly it's kind of a boring deck to use, not as bad as burn or mill, but I almost want to switch back to my Desert Twister deck even though I know it's not definitely gone down in the ranks.
