Once per turn, during the Standby Phase: Roll a six-sided die, and place counters on this card (max. 6), up to the result. When a monster effect is activated on your opponent's field, or once per battle, during damage calculation, if your opponent's monster attacks: You can remove 1 counter from this card, then target 1 of those monsters; toss a coin and call it. If you call it right, Special Summon 1 monster that mentions "Dark Time Wizard" from your Deck, and if you do, until the end of this turn, change the targeted monster's ATK to 0, also negate its effects.
Reversal Box — Power Evaluation
Final Score: 53 ± 8 · Confidence: Medium
- Intrinsic: 52 · Deck: 54 · Meta: provisional
- Primary role: Removal / Negation · Secondary: Extender
Why it scores here
Reversal Box converts a set continuous trap into a conditional answer: when an opponent's monster effect activates or a monster attacks, it can spend a dice-placed counter, call a coin, and on a correct call Special Summon a Dark Time Wizard-mentioning monster from the Deck while negating the targeted monster and setting its ATK to 0. The score comes from the 50% coin-gated negation and the Deck-dependent summon, not from its body (it is a trap with no material value). Its real-world inclusion across 6 archetypes lifts deck portability, but the 13-deck sample shows near-identical partner lists and no combo evidence, so the score stays in the mid-range.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Set in the S/T zone and triggered by opponent effects or attacks; the dice counters build up during the Standby Phase, and no searcher or combo-start route is in the evidence (inferred, with partner inclusion of 13/13 decks confirming it is practically live). (verified/inferred) |
| Combo & Conversion | 40 | Its text converts into one Special Summon from the Deck plus a negation, but no recorded boards show it as a starter or payoff, so conversion stays text-only inference. (inferred) |
| Resource Economy | 45 | No card cost or card draw; the Special Summon adds one body from the Deck for no hand cost, and the coin call can fail with nothing returned. (verified) |
| Effect & Interaction | 55 | Negates a monster's effects and sets its ATK to 0 on a correct coin call, once per battle or per monster effect, and this is a real reactive answer that is coin-gated and counter-limited. (verified) |
| Material Utility | 5 | A continuous trap is not a monster and cannot be material; its contribution here is zero. (verified) |
| Resilience & Flexibility | 40 | Sits face-up as a continuous trap and can be removed by trap or spell removal; its counter pool and coin-gated trigger add fragility, while multi-turn counter stacking gives some recovery. (inferred) |
| Deck-Building Efficiency | 70 | One copy in each deck (13/13 at 1 copy), no garnet or lock, and it occupies one slot with a Dark Time Wizard theme engine; cheap to run as a single trap. (observed) |

Evidence & gaps
- Verified: Trap card, continuous, Dark Time Wizard archetype, TCG and OCG legal; Negation and ATK-0 are conditional on a correct coin call; Single-copy decks (13/13) with 100% partner overlap on the listed cards
- Observed: Appears in 13 decks across 6 archetypes, all in main deck; Top-card context: not a top card (no ranking data)
- Inferred: Continuous-trap removal is its main counter; Cheap to run as one slot in the Dark Time Wizard theme
- Data gaps: no combos supplied, so combo conversion is text-only no guides supplied no banlist token, assumed 3 copies (unlimited) no usage statistics (StatisticsCard) for archetype inclusion identical 100% partner overlap across 9 cards suggests near-duplicate deck lists
