Light-Imprisoning Mirror — Power Evaluation
Final Score: 57 ± 8 · Confidence: Medium
- Intrinsic: 55.4 · Deck: 57.5 · Meta: provisional
- Primary role: Floodgate/Control · Secondary: Negation/Interaction
Why it scores here
The card's power is its continuous negation of LIGHT monster effects on the field and in the Graveyard, which is real but limited to one attribute. Its 400/400 deck inclusion across 104 archetypes and its view count confirm it is practical and always available, but under the rubric that reach earns no points beyond the accessibility and deck-cost axes. Because it builds nothing, has no material value, and has no combo evidence, its combo and material axes stay near zero, which keeps the final score in the mid-50s.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 62 | Present in all 400 sampled decks at an average of 2.03 copies, but it is a backrow trap with no searcher or combo routes in the evidence (observed). |
| Combo & Conversion | 10 | Zero recorded combo boards and the text creates no bodies or extra board, so it converts nothing by itself (verified). |
| Resource Economy | 30 | It answers an opponent effect one-for-one and returns no card advantage or refuel (inferred from text). |
| Effect & Interaction | 55 | Continuous, field-and-GY negation of all LIGHT monster effects is broad within its attribute but blank against every other attribute (verified). |
| Material Utility | 0 | A Trap card cannot be used as material, so this axis is zero (verified). |
| Resilience & Flexibility | 50 | Works from the field and the Graveyard, but as a face-down backrow card it can be destroyed by backrow removal (inferred). |
| Deck-Building Efficiency | 65 | Two copies on average with no garnet or lock; it occupies one slot and is cheap to run (observed). |
Calculation
Weight profile: 0.7 Floodgate/Control + 0.3 Removal/Negation. Intrinsic ≈ 55.4, Deck ≈ 57.5, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Negates all LIGHT monster effects on the field and in the Graveyard (verified: card text)
- Continuous, so it stays active without a chain each time (verified: card type)
- Included in all 400 sampled decks across 104 archetypes (observed: deck data)
Weaknesses
- Has no effect on monsters of other attributes (verified: card text)
- No combo evidence, so it builds no board or card advantage (observed: combo data is empty)
- Sits in the backrow and can be destroyed by backrow removal (inferred)
Counters / choke points
- Backrow destruction while it is face-down or face-up (inferred from trap placement)
- Non-LIGHT monster effects, which the card does not reach (verified: card text)
Best use
Floodgate/Control. Decks: Main-deck staple slot in decks that need to stop LIGHT monster effects (the attribute mix of the sampled decks is not in the evidence). Suggested copies: 2.
Evidence & gaps
- Verified: Continuous Trap that negates all LIGHT monster effects on the field or in the Graveyard (card text); Present in 400 of 400 sampled decks as a main-deck card at an average of 2.03 copies (deck data)
- Observed: Spread across 104 distinct archetypes, with 87.2% of decks in gameplay type 7 (deck data); Usage statistics show 100% inclusion in Flamvell and Elemental HERO at 2 typical copies (usage statistics)
- Inferred: Its LIGHT-only scope limits reach against non-LIGHT threats (text-based inference); Backrow destruction is a practical answer to its continuous effect (inferred from trap placement); Accessibility is high because it is a staple in the sample, not because of a searcher route (inference)
- Data gaps: No combos supplied, so combo conversion rests on card text alone No banlist token, so the copy limit is assumed to be 3 No rulings or attribute-mix data for the sampled decks, so the LIGHT-monster reach cannot be quantified
