Naturia swarms really well allowing you to win fast. The caveat is that you need 2 essential cards, and you are not guaranteed to get them in your opening hand. With all that said, it's really cheap to make, so from a cost to win ratio, its one of the best for beginners, even if its win ratio is relatively low compared to other more competitive decks.
Cont: Naturia can be further reinforced to survive long enough to execute the combo, but the main combo remains the same, and if you have the resources to make a consistent performing Naturia deck, you probably have the resources to make other decks and progress from Naturia. If a player does continue playing Naturia at that point, I believe they are either trolls or idiots.
