Executive Summary

The "Number" cards are an expansive and unique collection of Xyz Monsters from the Yu-Gi-Oh! ZEXAL era. In lore, they are fragments of a celestial being's memory, which translates to a diverse series of over one hundred and sixty unique monsters spanning countless Ranks, Types, and effects. Rather than a synergistic archetype, "Number" is a broad designation that lacks a cohesive internal engine. Its power is instead unlocked through powerful, dedicated support cards and external engines�most notably the Onomat engine�designed to rapidly assemble materials for their summon.

Competitive Analysis

Strengths

  • High Ceiling: Can produce nearly unbreakable boards with multiple negations.
  • Consistent Engine: Numerous searchers and one-card starters make the core combo highly accessible.
  • Vast Toolbox: Access to the entire "Number" lineup and generic Xyz monsters like Zeus offers great flexibility.

Weaknesses

  • Choke Points: The combo is linear and highly vulnerable to well-timed hand traps on key searchers or extenders.
  • Board Breakers: Can struggle going second against established boards, and is susceptible to cards like Lava Golem or Kaijus.

  • Number 16: Shock Master
  • Number 42: Galaxy Tomahawk
  • Number 86: Rhongomyniad
