NEXUS

Executive Summary

The B.E.S. (Big E.S.p.A.C.E. Ship) archetype is a Machine-type theme centered on large beatstick monsters that use a counter system for survival. Originally hampered by a design flaw that pitted its two core mechanics against each other, modern support has transformed the strategy. The deck now relies on its powerful Field Spell, B.E.F. Zelos, and synergy with external Machine archetypes to function as a potent hybrid control or board-breaking threat, a long way from its origins as a fleet inspired by a classic video game.

Core Components: The B.E.S. Fleet

The Starships

B.E.S. Big Core MK-3

The primary boss monster for the recursion loop. An essential Level 8 body for powerful Rank 8 Xyz plays.

B.E.S. Blaster Cannon Core

Provides valuable backrow removal with its Quick Effect and serves as another key Level 8 for Xyz Summons.

B.E.S. Big Core MK-2

A flexible Level 6 monster that can be summoned without tribute, providing material for Rank 6 or Link plays.

Command & Control

B.E.F. Zelos

The heart of the deck. Searches Boss Rush, protects your monsters, and Special Summons them from the hand.

Boss Rush

A Continuous Spell that provides endless recursion, Special Summoning a new B.E.S. monster from the Deck when one is destroyed.

Hybrid Engines (Kaiju / Machina)

External engines are crucial for consistency and power, providing either board-breaking OTK potential or a resilient control setup.

Endboard Analysis

Kaiju Variant Endboard

Number 38: Hope Harbinger Dragon Titanic Galaxy
Missing: 63767246

The primary goal is an OTK when going second. If forced to go first, the endboard focuses on a powerful Rank 8 Xyz monster to control the game.

  • Rank 8 Control: Usually ends on Number 38: Hope Harbinger Dragon Titanic Galaxy for a crucial spell negate.
  • Recursion Ready: Has Boss Rush active to replace any destroyed B.E.S. monster during the End Phase.

Machina Variant Endboard

Machina Citadel
Missing: 87074380

This build aims for a highly resilient Turn 1 board with multiple layers of protection and reactive disruption.

  • Dual Recursion: Boss Rush and Machina Citadel create a loop that punishes destruction effects.
  • Layered Negation: Combines the protection of Zelos with a Rank 8 negate like Number 38.
  • Sticky Board: The combination of effects forces the opponent to use non-destruction removal to clear threats.

Competitive Analysis

Strengths

  • Incredible Protection: B.E.F. Zelos makes B.E.S. monsters immune to targeting and destruction effects.
  • Persistent Recursion: The combination of Boss Rush and the Machina engine creates a board that is very difficult to clear.

Weaknesses

  • Zelos Dependency: The entire strategy crumbles if B.E.F. Zelos is removed from the field.
  • Inconsistent: Requires running multiple search cards for the Field Spell, which can lead to brick hands.
  • Vulnerable to Non-Destruction: Weak to effects that banish, shuffle, or Tribute monsters, bypassing Zelos's protection.

Hybrid Strategies

  • Kaiju OTK: Uses the Kaiju engine to break the opponent's board and push for a quick one-turn kill.
  • Machina Control: Integrates the Machina engine for a defensive, control-oriented build with multiple layers of recursion.
