Mind Mirror Force — Power Evaluation
Final Score: 66 ± 6 · Confidence: Medium
- Intrinsic: 66.3 · Deck: 65.1 · Meta: provisional
- Primary role: Removal / Negation · Secondary: Board breaker
Why it scores here
The card's value is its conditional mass effect: it negates and destroys every face-up card the opponent controls, which is why effect_interaction carries the score. Its activation windows (attack by the highest-ATK monster, opponent monster effects that destroy, opponent monster effects during your turn) are broad, but the uncounterable clause only applies at 5+ opposing face-up cards, so early-board use is negatable. It builds nothing for you, so combo_conversion stays low, and it contributes no material value. Inclusion in all 400 sampled decks confirms it is easy to access and fits many homes, but guardrail 3 means that frequency does not raise the score.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 68 | A set trap with a set-turn activation clause, run in 400 of 400 sampled decks at about 2 copies on average, so it is usually live when needed (verified: card text; observed: decks_evidence). |
| Combo & Conversion | 25 | No recorded boards, so there is no measured starter or payoff role; the card only removes opposing cards and builds no board of its own (inferred: text only, combos_evidence is empty). |
| Resource Economy | 65 | One trap card can destroy several opposing face-up cards, a 1-for-many swing when the opponent has a wide board, but nothing returns to your side (verified: card text). |
| Effect & Interaction | 85 | Mass negate-and-destroy with four activation windows, uncounterable at 5+ opposing face-up cards, and a set-turn activation clause makes it hard to play around (verified: card text). |
| Material Utility | 5 | A trap is never summoned or used as material, so it provides no body value (verified: card type). |
| Resilience & Flexibility | 45 | Negatable when the opponent controls fewer than 5 face-up cards, and it cannot attack directly for the following turn, which is a cost (verified: card text; inferred: negation risk). |
| Deck-Building Efficiency | 80 | Normal (non-garnet) trap with no self-lock; typically 2 copies across 106 archetypes, so the slot cost is low (observed: decks_evidence; verified: frame and card text). |
Calculation
Weight profile: 0.7 Removal/Negation + 0.3 Board breaker. Intrinsic ≈ 66.3, Deck ≈ 65.1, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Mass negate-and-destroy of opponent's face-up cards, a large swing when the opponent has a wide board
- Several activation windows, including on the opponent's highest-ATK attack and on monster effects that destroy
- Set-turn activation and a low copy cost make it easy to run across many archetypes
Weaknesses
- Negatable and not uncounterable until the opponent controls 5 or more face-up cards
- Builds nothing for your own board and has no material or recovery value
- Your monsters cannot attack directly until the end of the next turn after it resolves
Counters / choke points
- Opposing negation or counter-trap cards, including Solemn Judgment, which appears in these decks as a partner (inferred)
- Opponent keeping fewer than 5 face-up cards, which removes the uncounterable clause (verified: card text)
Best use
Set trap for opposing-board interaction, one of the standard backrow interaction slots. Decks: Branded, Elfnote, Sky Striker, Fiendsmith, Dominus, Power Patron. Suggested copies: 2.
Evidence & gaps
- Verified: Card text: uncounterable only when the opponent controls 5+ face-up cards, set-turn activation clause, mass negate and destroy of face-up opposing cards, three activation timings; Present in 400 of 400 sampled decks, averaging 2 copies (distribution 1:119, 2:164, 3:117)
- Observed: Spread across 106 distinct archetypes; 98.5% of decks are gameplay type 7; Co-occurs with Maxx "C" (95.8%), Ash Blossom & Joyous Spring (88%) and Droll & Lock Bird (83%); StatisticsCard inclusion of 66.7% in Evilswarm (typical 3 copies), the only archetype row available
- Inferred: Strongest when the opponent has built a wide board before combat, and weak early or against an empty field; Set-turn clause makes it a flexible backrow interaction slot
- Data gaps: No combos supplied, so combo conversion and starter/material roles are text-only inference No guides supplied No banlist token; assumed 3 copies (unlimited) usage_statistics covers only one archetype (Evilswarm) legal_copies is empty for both TCG and OCG No rulings supplied for the uncounterable clause or the set-turn clause
