When a Spell/Trap Card, or monster effect, is activated, while you control a "Number" Xyz Monster: Negate the activation, and if you do, destroy that card. If a "Number" Xyz Monster(s) you control is destroyed by battle or card effect, while this card is in your GY: You can Set this card, but banish it when it leaves the field. You can only use 1 "Numbers Protection" effect per turn, and only once that turn.
Numbers Protection — Power Evaluation
Final Score: 59 ± 6 · Confidence: Medium
- Intrinsic: 56 · Deck: 61 · Meta: provisional
- Primary role: Negation/Interaction · Secondary: Recovery/Recursion
Why it scores here
Numbers Protection is a conditional, once-per-turn negate-and-destroy trap that works only while a "Number" Xyz is on the field, so its value is interaction density inside one archetype. It converts well into disruption on any Spell/Trap or monster effect, and its GY Set-and-banish clause gives a single recursion. High deck inclusion (400 of 400 decks, 35 archetypes) confirms it is a reliable staple for this archetype family, but that frequency does not raise the score. The Anti-Nibiru and basic Utopia boards score 100 on power_index, yet those are board-level structural scores, and the card appears with no starter, searched or material role, so they earn it no credit.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | A set trap that needs a live Number Xyz to activate, but it is in 400 of 400 decks at 1 copy each, so access is routine in-archetype (observed). |
| Combo & Conversion | 25 | It appears in 2 of 2 recorded combos with an empty role_in_combo and 0 starter, searched or payoff roles, so it builds no board on its own (observed). |
| Resource Economy | 55 | Negating and destroying a card is a one-for-one exchange that also leaves the trap for your own use, and the GY Set-and-banish clause refuels one copy at most (verified). |
| Effect & Interaction | 70 | It negates any Spell/Trap activation or monster effect while a Number Xyz is controlled, which is broad and hard to play around within the archetype, though it is a face-down trap (verified). |
| Material Utility | 5 | A Trap card with no material or level/attribute value (verified). |
| Resilience & Flexibility | 50 | The GY Set clause is limited to once per turn and needs a Number Xyz to be destroyed, so it is recoverable in some spots but not in most (verified). |
| Deck-Building Efficiency | 65 | It is one copy with no garnet or lock, but it is archetype-restricted, so it only pays off in Number-based decks (inferred). |
Calculation
Weight profile: 0.7 Removal/Negation + 0.3 Recovery/Recursion. Intrinsic ≈ 56, Deck ≈ 61, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Broad negation reach across Spell/Trap and monster effects while a Number Xyz is controlled
- Single-copy, low-cost slot in its home archetype
- Recursion from the GY when a Number Xyz is destroyed
Weaknesses
- Conditional on a live Number Xyz, so it is dead without one
- Once-per-turn limit on the GY recursion
- No material or body value
- Face-down trap that can be removed before it is used
Counters / choke points
- Backrow removal or destruction of the set trap
- Making the Number Xyz leave the field before activation
Best use
Single-copy negate/protection trap for Number-based Xyz decks. Decks: Utopia, Onomat, Gagaga, Dododo, Chaos Chimera OTK. Suggested copies: 1.
Evidence & gaps
- Verified: Negates Spell/Trap activations and monster effects while a Number Xyz is controlled, then destroys the card; GY Set-and-banish clause triggers when a Number Xyz is destroyed; once per turn; Trap card with no material value; 1 copy in 367 of 400 decks
- Observed: In all 400 sampled decks at a mean of 1.11 copies; Appears in 2 of 2 recorded combos with no starter, searched or material role; Usage statistics show 100% inclusion in Utopia and Heraldic, both at 1 copy
- Inferred: Relevant mainly in Number-based decks, which limits access outside its archetype; Recursion value is limited to the once-per-turn GY clause
- Data gaps: no banlist token; assumed 3 copies (unlimited) combos_evidence role_in_combo arrays are empty, so combo roles rely on the as_* counts only only 2 recorded combos, so combo conversion is thinly evidenced 400 of 400 sampled decks run it, so the deck sample may not represent the wider player base
