NEXUS

Executive Summary: Two Generations

The "Spider" collection is not one cohesive archetype, but two distinct generations of cards separated by over a decade.

The Legacy Web (2009) focused on a slow, battle-centric control strategy of forcing monsters into Defense Position. This strategy is entirely obsolete in the modern game.

The Modern Swarm (2023) introduced a hyper-consistent, two-card combo engine that completely supplants the old strategy. This modern engine is a proactive, game-ending OTK strategy designed to swarm the field and summon high-Rank DARK Xyz monsters. This analysis will focus exclusively on this modern, competitively viable engine.

Anatomy of the Modern Engine

The Progenitor: Mother Spider Splitter

Mother Spider Splitter
Missing: 34034150

Role: The primary, one-card starter.

  • Inherent Summon: Can Special Summon itself from the hand if you control no monsters, saving your Normal Summon.
  • The Splitting Effect: Tributes itself to Special Summon up to 3 Baby Spider from your hand and/or Deck.
  • Level Modification: All summoned `Baby Spider`s become Level 5.
  • Critical Restriction: Locks you into Special Summoning only DARK Xyz Monsters from the Extra Deck for the rest of the turn. This defines the entire Extra Deck.

The Swarm: Baby Spider

Missing: 60023855

Role: The versatile combo tool and extender.

  • On-Field Effect: Can Tribute 1 DARK monster (itself) to increase the Levels of all other "Baby Spiders" you control by the Tributed monster's Level. This is the key to making Rank 10s.
  • Graveyard Effect: Can pay half your LP, banish itself from the GY, and detach 1 material from your DARK Xyz Monster to Special Summon 1 DARK monster from your GY. This is a powerful extender for the OTK.

  • Global ATK Boost: All monsters you control gain ATK/DEF equal to the *difference* between your LP and your opponent's LP.
  • Synergistic Cost: The Baby Spider's "pay half LP" cost is now a benefit, typically granting a 4000+ ATK boost to your entire field.

Number 77: The Seven Sins

  • Massive Attacker: Starts with 4000 ATK, which becomes 8000+ ATK with Tarantula's boost, enabling an easy OTK.
  • Board Wipe: Can detach 2 materials to banish all opposing Special Summoned monsters (non-targeting).
  • Protection: Can detach 1 material to protect itself from destruction.

The Ecosystem: Support & Synergies

The two-card engine cannot function in a vacuum. Building a successful Spider deck is less about the Spiders themselves and more about constructing the most efficient web of support cards to find and enable Mother Spider Splitter.

Consistency Web

Resonance Insect
Missing: 96938986

Resonance Insect is the most important non-Spider monster. When sent from field to GY (e.g., via Link Summoning Linkuriboh or Salamangreat Almiraj), it searches Mother Spider Splitter (a Level 5 Insect).

Beetrooper Alliance

Beetrooper Scout Buggy
Missing: 2656842

The Beetrooper engine provides swarming and extension. Beetrooper Armor Horn grants an additional Normal Summon, allowing you to summon Resonance Insect, Link it off for a search, and still have your Normal Summon.

The Legacy Web (Historical)

Mother Spider
Missing: 17021204

The original 2009 "Spider" cards (Mother Spider, Spyder Spider, Underground Arachnid) are fundamentally incompatible with the modern engine. Their slow, battle-focused strategy has no synergy with the go-second OTK plan and should not be included in a competitive build.

Competitive Analysis

Strengths

  • Explosive OTK: Capable of ending the game from a single card if uninterrupted.
  • High Consistency: The deck is built around finding its one-card starter (Splitter) via multiple generic Insect searchers.
  • Budget-Friendly: The core engine and its Xyz targets are very affordable, making it a powerful rogue option.

Weaknesses

  • Glass Cannon: The deck is extremely fragile. A single, well-timed hand trap (Ash Blossom, Impermanence) on Mother Spider Splitter's effect ends the turn completely.
  • Attribute Lock: Vulnerable to floodgates like Gozen Match (as all main monsters are DARK).
  • No "Plan B": If the OTK fails, the deck has almost no follow-up, grind game, or defensive options.

Tech & Support

  • Small World: An excellent generic searcher that can bridge almost any Insect in the deck to Mother Spider Splitter.
  • "Kaiju" Monsters: Insect-Type Kaijus like Kumongous are searchable by Resonance Insect, providing built-in removal.
  • Board Breakers: As a "go-second" deck, it relies heavily on cards like Forbidden Droplet and Dark Ruler No More to bypass negations.

Banlist Impact

The Spider archetype itself is largely untouched by the TCG banlist, but key synergistic cards it relies on are affected.
