Various "Naturia" monsters in the Naturia Forest.
"Naturia" (ナチュル Nachuru), known as "Naturu" in the Japanese version, is an EARTH-Attribute archetype from Duel Terminal - Justice Strikes Back!!, Duel Terminal - Demon Roar God Revival!!, Duel Terminal - Champion of Chaos!! and Duel Terminal - Pulse of the Trishula. Naturia monsters are composed of various Types, but all of them are related to forest life (much like Sylvan, albeit different), such as Plants, Insects, Rocks, a few Beasts, and even a Dragon. Their effects center around limiting, or gaining advantages from, the opponent's Spell, Trap, and Monster Cards when activated/Summoned. Despite their low ATK and DEF, if built correctly, Naturia monsters can be surprisingly quick and control the field easily.
Almost all Naturia monsters have effects that can be activated to respond at any action your opponent may commits, thus this deck's main strategy always revolves around control or even stun-esque approach. In fact, their main Synchro Monsters (except "Naturia Leodrake") have effects that can negate the activation of specific card types (Spell/Trap/Effect Monster), further reinforcing the control aspect. "Naturia Bamboo Shoot", in particular can completely blocks your opponent from activating any Spell/Trap Card (if Tribute Summoned by Tributing Naturia monster), thus becoming center focus in most Naturia-based decks.
Besides Bamboo Shoot, there are also Naturia monsters whose effects reacts to your opponent's action regarding their monster, like "Naturia Mantis" (can destroy monsters the moment it is Normal Summoned), "Naturia Horneedle" (can destroy monsters upon being Special Summoned), "Naturia Antjaw" (can Special Summon Naturia monsters each time your opponent Special Summons), and "Naturia Pumpkin" (Special Summon another Naturia monster if your opponent has a monster). For defense purpose, they have cards like "Naturia Cliff", "Naturia Cherries", and "Naturia Beans", while "Naturia Sacred Tree" can improve the deck's consistency, and "Naturia Marron" can recycle monsters in place of "Pot of Avarice" (which is currently Forbidden).
Their Fusion Monsters, "Naturia Exterio" and "Naturia Gaiastralio" have powerful control effects, combined with their high ATK, can be easily Summoned with "Miracle Synchro Fusion" or "The Earth - Hex-Sealed Fusion" (for "Exterio"), can be very devastating to your opponent as well.
This deck centered around utilizing Naturia monsters to respond to your opponent's moves, focusing mostly on control-based approach. "Naturia Mantis" and "Naturia Horneedle" can destroy your opponent's monster upon being Summoned, "Naturia Antjaw", "Naturia Cosmobeet", "Naturia Cherries", "Naturia Cliff" and "Naturia Pumpkin" provides swarming capabilities, "Naturia Butterfly" and "Naturia Stinkbug" can stop your opponent's attacks, "Naturia Marron" and "Naturia Eggplant" recycle your cards, and "Naturia Bamboo Shoot" and "Naturia Rosewhip" can restrict your opponent's Spells and Traps. Since Naturia monsters usually has low ATK, cards like "Naturia Fruitfly" and "Gaia Power" are sometimes used, to weaken your opponent's monster and strengthening your own, respectively. To increase consistency, cards like "Upstart Goblin", "Reckless Greed", "Pot of Duality", and especially, "Naturia Sacred Tree" can be included as well.
This build utilizes Naturia monsters along with Plant-Type supports such as "Lonefire Blossom" and "Dandylion", aiming to compose locks as soon as possible with "Naturia Bamboo Shoot" combined with the Plant Princesses such as "Tytannial, Princess of Camellias" and/or "Talaya, Princess of Cherry Blossoms". This Deck have easy swarming capabilities thanks to "Lonefire Blossom", "Chirubimé, Princess of Autumn Leaves", "Meliae of the Trees" and "Miracle Fertilizer", while also capable of using Plant-related supports like "Mark of the Rose", "Pollinosis", and "Queen of Thorns".
This variant combine Naturia monsters along with the suite of Traptrix cards. "Traptrix Myrmeleo" and "Traptrix Dionaea" are the ones commonly used to provide more control aspect to the deck in form of Trap Hole cards such as "Traptrix Trap Hole Nightmare" and "Time-Space Trap Hole", while also allowing access to plethora of Rank 4 Xyz Monsters. Naturia cards like "Naturia Cliff" and "Naturia Cherries" are commonly used to provide defensive capabilities while also provides Tribute fodder for "Naturia Bamboo Shoot". "Naturia Sacred Tree" is very integral in this deck, allowing you to get the right monster at the right time, improving this deck's consistency drastically.
Focused around Summoning "Naturia Bamboo Shoot" as soon as possible, combined with Anti-Meta cards such as "Thunder King Rai-Oh", "Doomcaliber Knight", and "Fossil Dyna Pachycephalo". If combined with "Majesty's Fiend" and "Fossil Dyna Pachycephalo" or "Cactus Bouncer", you can prevent your opponent from doing basically everything.
Naturia Reversal OTK
This deck focusing on interactions between "Naturia Mosquito" along with small-ATK Naturia cards such as "Naturia Beans", "Naturia Cherries" and "Naturia Cliff", to create OTK strategy in the same way as "Daigusto Sphreez" in Gusto decks. To get "Mosquito" easier, cards like "One for One" and "Inferno Reckless Summon" can be used to provide the necessary components for completing the OTK.
Naturia decks, despite their capabilities of composing powerful and sturdy locks, but they're naturally slow, so faster decks usually have easy time of exterminating them before they gather the necessary components for their lock. "Skill Drain" can single-handedly destroy this deck completely, since Naturia monsters are so heavily-dependent on their monster effects, and most of them have low-ATK as well that cards like "King Tiger Wanghu" and "Deck Devastation Virus" can easily prey on them.
Naturia decks focusing on "Naturia Bamboo Shoot" also have even more challenges, since they need to protect Bamboo Shoot at all costs in order to keep their position in a Duel. "Effect Veiler" in particularly dangerous in this aspect, since it can negate Bamboo Shoot's effect permanently (since Bamboo Shoot will "forget" that it was Tribute Summoned with Naturia monster if its effect's negated). "Solemn Warning" also needs to be in consideration at all times, since it can destroy Bamboo Shoot when it is Summoned and possibly ruin your entire strategy. Also, it is vulnerable to monster effects and monsters that has higher than 2000 ATK, so cards like "Safe Zone" that can protect Bamboo Shoot from both threats are highly recommended.
"Dimensional Fissure", "Macro Cosmos", and "Banisher of the Radiance" can cripple this deck as well, since "Naturia Cliff", and "Naturia Cherries" cannot activate their effects if they're banished, while also rendering "Naturia Marron", "Naturia Eggplant" and "Naturia Mantis" useless. "Rivalry of Warlords" can also prevent this deck from swarming, since Naturia monsters have different Types.
