I found that no one ever ashes Small World, so I wanted to make a deck that heavily punishes your opponent for doing that by adding Lava Golem. Honestly a welcome consistency card for getting to network as well since Lava Golem and Numeron Wall are both Fiends. There aren't many monsters in the deck so the lines of what gets to what are pretty simple.
Reveal Wall ----> Ash ----> Lava Golem and vice versa
Reveal Gadarla ----> Lava Golem ----> Vanity's Ruler or Ash or Wall
I am main decking Vanity's Ruler and Solemn Judgment because there's enough blowout cards to deal with basically any deck, so you have the room to just play going 1st cards as well in case someone figures out your strategy and thinks they can make you start. You don't need to do this, you can just play even more going 2nd cards if you wish.
As for the extra deck, I'd say the only cards you care about are the numerons obviously, the Apollousa, the Saryuja, and the Megaclops. Cards like Goddess seem good and can catch your opponent off guard, but Borrelcode and Zeroboros could be anything else that you prefer.
In the side, the only card of note is probably Link Bound, I found this card to be good at clearing monsters off of your field so you can activate network while also recycling a monster and potentially fixing your hand. You probably only ever want to see this card going 1st so that's why it's in the side.
