Activate only if you control a "Number" monster. "Number" monsters on the field cannot be destroyed by card effects, and cannot be destroyed by battle except with another "Number" monster. When a "Number" monster you control is destroyed, destroy this card.

Why it scores here
Number Wall provides strong protection against destruction effects, a critical defensive role in Number decks where preserving the board state is essential. The activation requirement and self-destruct clause keep it from being a generic staple, but within Number homes it is clean and efficiently costed. The card's protection is primarily passive, not active disruption, and it generates no card advantage. Its value lies in preserving existing board state rather than in building one.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 72 | Requires a Number monster on field to activate, limiting it to Number decks; 50 decks in the sample run it, confirming high accessibility within those homes. (verified) |
| Combo & Conversion | 35 | As a trap card with no combo examples, it does not build boards; it preserves existing ones after prior combo execution. (inferred) |
| Resource Economy | 32 | Provides no card advantage, searches, or recursion; destroys itself when a Number is destroyed, yielding net -0 to -1 in its protection scenarios. (inferred) |
| Effect & Interaction | 68 | Blocks destruction by card effects and battle except with other Number monsters, covering a broad range of meta removal tactics. (verified) |
| Material Utility | 8 | A trap card with no type, level, or attribute cannot serve as material even when negated. (inferred) |
| Resilience & Flexibility | 40 | Dependent on at least one Number monster remaining on field; self-destructs if all Numbers are destroyed, limiting multi-turn resilience. (inferred) |
| Deck-Building Efficiency | 72 | Slots cleanly into Number decks with no brick risk; requires archetype commitment, making it archetype-specific rather than generic splashable. (verified) |
Calculation
Weight profile: Floodgate / Control. Intrinsic ≈ 57, Deck ≈ 58, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Strong protection: blocks destruction by card effects, covering Raigeki, Dark Hole, Evenly Matched, and other common meta removal
- Clean in Number decks: minimal brick risk, synergizes with the archetype's core strategy
- Flexible protection: covers both card-effect and battle destruction (except to other Number monsters)
Weaknesses
- Requires Number monster on field to activate, restricting it to Number decks only
- Self-destructs if all controlled Number monsters are destroyed, creating fragility when board state collapses
- Generates no card advantage or resource refuel, purely defensive
- Trap card vulnerability: spell speed 1, can be preempted or destroyed before activation
- Battle destruction vulnerability outside the Numbers mirror (battle protection only blocks non-Number attacks)
Counters / choke points
- Board wipes that remove all Number monsters (Ice Dragon's Prison, Kaijus, etc.) force the trap to self-destruct
- Pre-activation trap destruction (MST, Cosmic Cyclone, Harpie's Feather Duster if set)
- Non-destruction removal (banishing effects, forced discard) bypasses the protection
- Going-second decks that can remove all Numbers before their turn ends
Best use
Board protection / Floodgate. Decks: Utopia, Galaxy Photon, Clear World, Zexal, Onomat.
Evidence & gaps
- Verified: Card text: protection from destruction by card effects and battle (except other Number monsters); Activation requirement: must control a Number monster; 50 decks running it in Number-based archetypes across TCG/OCG/MasterDuel; 18 distinct archetype homes, all Number-themed or Number-inclusive; Top partners are all Number monsters (38, 39, C39, Double, Dragonar, etc.)
- Observed: 24% inclusion in Utopia decks (primary home); 1.24 avg copies per deck, with distribution favoring 1 copy (84%), but some 2-3 copies (16%); 70% co-deck rate with Number 38, 62% with Number 39, 58% with Astraltopia; Appears exclusively in main deck (0 side deck appearances)
- Inferred: Trap card with no material utility, cannot serve as XYZ/Synchro/Fusion/Link material; Self-destruct clause ties card to Number board state resilience; No card advantage generation; purely protective/defensive; Accessibility high within Number decks, gatekeeping restriction prevents generic splashability; Protection against destruction effects covers common meta removal (Raigeki, Dark Hole, Evenly Matched)
- Data gaps: No combos supplied (0 combos) — cannot assess turn-1/turn-2 board integration or actual combo conversion in practice No guides supplied (0 guides) — no expert context on deck-building decisions or tech applications No usage statistics (StatisticsCard available: false) — archetype inclusion % and consistency inferred from 50-deck sample only, not larger statistical sample No banlist data — assumed 3 copies legal in all formats
