Duality — Power Evaluation
Final Score: 58 ± 8 · Confidence: Medium
- Intrinsic: 54 · Deck: 61 · Meta: provisional
- Primary role: Recovery / Recursion · Secondary: Starter / Combo enabler
Why it scores here
Duality converts its GY presence into value: once per turn it banishes itself from the GY to shuffle one LIGHT and one DARK monster back into the Deck and draw 1, and its other effect swaps a LIGHT or DARK body into a same-Type, same-Level monster of the other attribute. The score comes from access, cheap generic LIGHT/DARK requirements and reach across 69 archetypes, not from stats. The 400-deck sample shows 400/400 running it with 1.97 average copies and strong partners, but that sample looks drawn from decks already containing the card, so it confirms a staple role rather than adding power. With no combo data, combo conversion rests on text inference, which caps the score in the mid-50s.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 68 | Live from hand or GY across 69 archetypes and 400 sampled decks, but the summon needs a matching LIGHT/DARK tribute and target (decks: 400 sampled, 100% running; inferred from text). |
| Combo & Conversion | 45 | No combo boards supplied; the tribute-and-swap summon and the GY draw are text-only conversion with no observed starter or payoff role (inferred). |
| Resource Economy | 58 | The GY effect banishes itself, returns two monsters to the Deck and draws 1, a refuel that roughly offsets the tribute cost of the summon effect (verified from text; refuel-to-draw value inferred). |
| Effect & Interaction | 5 | No negation, removal or hand-trap reach; it is a pure engine spell (verified from text). |
| Material Utility | 5 | A Spell card, not a monster body; the material it touches is a tribute and a summon target, not a body of its own (verified from text). |
| Resilience & Flexibility | 60 | Two separate effects usable from hand or Extra Deck and from the GY, each once per turn, so it stays live across zones and turns (verified from text; once-per-turn wording). |
| Deck-Building Efficiency | 70 | Three copies, no garnet or self-lock, and LIGHT/DARK tribute requirements that most decks can meet; avg 1.97 copies per deck in the sample (observed). |
Calculation
Weight profile: 0.7 Recovery/Recursion + 0.3 Starter/Combo enabler. Intrinsic ≈ 54, Deck ≈ 61, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Two independent effects, one usable from the hand/Extra Deck summon route and one from the GY
- GY effect refuels two monsters to the Deck and draws 1, recovering value from a dead GY
- Broad reach: 69 distinct archetypes in the sample, with consistent 1–3 copy use
- Cheap generic requirements (LIGHT or DARK monsters only), so it is easy to build around
Weaknesses
- Summon effect costs a tribute and needs a matching LIGHT/DARK body and a same-Type, same-Level target
- Both effects are once per turn each, limiting repeated value
- No opponent interaction of any kind
- Deck sample looks selected from decks that already contain it, so usage rates are not independent evidence of strength
Counters / choke points
- Spell negation or GY-targeting effects would shut down the GY draw (inferred from text; no counter data in evidence)
- Opponent interruption of the tribute/summon window would stall the summon route (inferred from text)
Best use
Recovery / Recursion with a LIGHT/DARK Special Summon route. Decks: Cyber Dragon, Cyberdark, Therions, Dogmatika, Bystial/Byssted, Branded, Cyberse. Suggested copies: 2.
Evidence & gaps
- Verified: Card text: tribute 1 LIGHT or DARK monster, then Special Summon a LIGHT or DARK monster from hand or Extra Deck with the same original Type and Level and a different original Attribute; Card text: during your Main Phase, banish this card from the GY to shuffle one LIGHT and one DARK monster from the GY into the Deck and draw 1; each effect once per turn; Formats: TCG, OCG, MasterDuel; Copy distribution in sample: 1 copy 125 decks, 2 copies 161, 3 copies 114 (avg 1.97)
- Observed: Appears in 400 of 400 sampled decks, across 69 archetypes and gameplay types 7, 6 and 4; Top partners in sample: Called by the Grave 72.8%, Ash Blossom & Joyous Spring 68.2%, Harpie's Feather Duster 55.8%
- Inferred: The GY effect is the main recovery value and the summon effect is the main access route; Combo conversion is high-potential but unmeasured, since no boards are supplied; Inclusion rate is partly an artifact of how the sample was drawn, so it does not raise the score
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only decks running it in the Main Deck 400/400 suggests the attached sample was drawn from decks already containing the card; inclusion rate is not an independent measure card text does not state activation timing, so hand-activation is not assumed
