Naturia Beast, Relevance in the Meta

1 EARTH Tuner + 1 or more non-Tuner EARTH monsters
During either player's turn, when a Spell Card is activated: You can send the top 2 cards of your Deck to the Graveyard; negate the activation, and if you do, destroy it. This card must be face-up on the field to activate and to resolve this effect.

Naturia Beast, one of the Naturia Synchros Trio (not considering Leodrake since he hasn't a negation effect), arguably the best among them. I named this card lots of times in the past, from Iron Chains, to Madolches, from Beast Synchro, to Karakuris and other lots of thingies. I noticed the strength of Karakuris, mainly, in this meta, with that Naturia Beast, but someone (Desmond Johnson) managed to show it to the world. I must admit that his build works a lot better than the one I was trying for this meta. It had pretty much the same basics, only that I played 3 decrees for the sake of drawing them as early as possible and go into a lock with Naturia Beast. However, they were quite the DDs, but sometimes they were way too useful, I'm still confused about them. Another thing Desmond noticed and I didn't was that Solar Wind Jammer could SS itself without monsters on the opponent's side.
Back on today's topic, Naturia Beast. Well, you should know by now what the next meta is going to look like, right? Mermails and Fire Fists till the release of Spellbook Judgment Day, where they'll become part of the meta, then, once HA7 is released, Evilswarms will be the main antimeta choice.
Beast is unstable in this meta, Spellbooks dies to it (aside Junon+3 Spellbooks, for that exact reason you should aim to the win as fast as possible), Fire Fists will be slowed down till they have a beater (tenken+something, reason why I used to play 3 decrees in my build), Evilswarms don't have access to Pandemic, but they can run over Beast with just Ophion (Decree is helpful here, too) while Mermails aren't really that affected, aside salvage and such, but they can kill beast with ease. For those reason, Naturia Beast is quite controversial.
However, when judging a certain card, you must always consider what type that card is: Infernity Launcher is way more broken than Mirage, even having the same effect, pretty much.
This card is the same thing: it is a synchro, thus it resides in the extra. Considering your extra a toolbox, as I always do, this card can be brought to the table when needed, and not waiting to draw it and being a DD from time to time.
If you are against Mermails, you'd rather go into Stardust than Beast, but against Spellbooks and Fire Fists the latter is awesome and against Evilswarm you'd go into a beater for their Ophion or, if you've got Decree, into Beast to attempt a lock, if they aren't too close to summon Ophion.
The decks that can afford easy summoning of Beast (and possibly barkion) have some potential not only for Beast itself, but even for the synchro ability: if you can summon Beast, you surely can summon Catastor, that's a great card itself, probably Stardust and Scrap and maybe Black Rose. Having that kind of toolbox (considering all of the XYZs, too) is a great arsenal for a player's deck.

I hope some other original deck makes it to the top of some important event, originality is always a good thing. Maybe some will be able to do so via Naturia Beast, who knows.

See Ya
