Spiders Are Insects?

Well, in Konami's universe they are lol. Anyway, Insects have recently received a nice boost from various core set support cards: Verdant Sanctuary, Lair Wire, Underground Arachnid, and the Spider archetype. Sanctuary in particular functions much like Black Whirlwind, allowing you to turn every monster you Summon into an additional copy from the deck. Lair Wire gives you versatile monster removal, Arachnid is one of the best Synchro monsters so far, and the Spider archetype boasts several card advantage machines in Spyder Spider and Mother Spider. Here's a rough decklist:

3 Koa'ki Meiru Beetle
3 Howling Insect
3 Magical Merchant
3 Spyder Spider
3 Mother Spider
2 Ground Spider
1 Plaguespreader Zombie
1 Shiny Black "C"

3 Earthquake
3 Verdant Sanctuary
2 Book of Moon
2 Gold Sarcophagus
1 Heavy Storm
1 Mystical Space Typhoon
1 Brain Control

3 Lair Wire
2 Bottomless Trap Hole
1 Trap Dustshoot
1 Curse of Anubis
1 Solemn Judgment

Merchant or Howling are our ideal openers. Howling can get Spyder Spider or Ground Spider, depending on your situation, while Merchant mills off Insects for Lair Wire while also loading up our Shiny Black "C" and Plague. Plague's self-revival effect allows us to bypass Mother Spider's "only Insects" drawback, by removing itself from play. Plague is a DARK Tuner and as such can be paired with any LV4 Insect to make Arachnid.

Beetle, Book, and Anubis all provide support for the DEF-mode minded Spiders. Earthquake/Mother Spider in particular is an amazing way to curb/punish your opponent's overextension. 2 monsters will fall just to her Summon condition, and you can take out the others by battle since their DEF likely can't withstand 2300 ATK.

The release of Infernity Beetle will make this archetype even more seamless, since it will open up more opportunities to spam Arachnids. It's both DARK and an Insect searchable by Howling, so its synergies with Arachnid's requirements and the deck's overall focus on the Insect-type should be obvious.
