Archfiend Strategy — Power Evaluation
Final Score: 51 ± 6 · Confidence: Medium
- Intrinsic: 49 · Deck: 53 · Meta: provisional
- Primary role: Searcher/Tutor · Secondary: Extender
Why it scores here
Archfiend Strategy scores on its reliable conversion of a Fiend or Archfiend card in hand or GY into a different Archfiend card from the Deck, plus an optional Pendulum add to the face-up Extra Deck, with a once-per-turn limit. It is a card-neutral searcher with no interaction and no material value, and its 1000 ATK Extra Monster Zone buff earns nothing because ATK is not a scoring driver. Its high deck count (237 decks, 93.7% co-occurrence with Royal Archfiend) confirms it is a dependable, cheap, single-home staple, but the combo role fields are all zero, so the score rests on deck fit rather than observed board conversion.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 65 | Searchable into the Deck-and-Fiend shell and present in 237 recent decks at 1.43 avg copies, though no as_searched or as_starter role data exists to confirm the route (observed, with inferred searcher route). |
| Combo & Conversion | 40 | Its 7 recorded combos average power index 4.9 with board and disruption at 0, so it converts into one extra card rather than a full board (observed). |
| Resource Economy | 45 | Banish-as-cost then add nets zero card advantage in every example (netCardAdvantage 0), with only the optional Extra Deck Pendulum add giving a small plus (verified from text and observed). |
| Effect & Interaction | 5 | No negation, removal or hand-trap effect on the card (verified from text). |
| Material Utility | 5 | It is a Spell with no material or level value and can never be used as material (verified from card type). |
| Resilience & Flexibility | 50 | Spell-type with a once-per-turn limit and two modes, with a continuous Extra Monster Zone effect while it stays on the field, so one negate ends it but it can persist across turns (inferred from text and race Field). |
| Deck-Building Efficiency | 70 | Cheap to run at 1 to 3 copies with no garnet or brick, but it uses a Field-zone slot in an archetype build (observed from copies distribution, inferred from race Field). |
Calculation
Weight profile: 0.7 Searcher/Tutor + 0.3 Extender. Intrinsic ≈ 49, Deck ≈ 53, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Converts a Fiend or Archfiend in hand or GY into another Archfiend card from the Deck, with a clean once-per-turn limit
- Core of a large Archfiend deck sample: 237 decks, 93.7% co-occurrence with Royal Archfiend, 33 distinct archetypes
- Cheap to run at 1 to 3 copies with no garnet cost
Weaknesses
- Card-neutral exchange with no net advantage and no direct board presence
- No effect interaction, negation or material value
- Combo data shows zero role tagging (starter, searched, material, payoff), so the conversion claim is only partly observed
- Its power depends on a Fiend or Archfiend in hand or GY, so the line can stall without one
Counters / choke points
- Negation of the card (generic spell negate; the Ash Blossom & Joyous Spring co-occurrence suggests an interaction-heavy meta shell)
- Hand disruption that takes away the Fiend or Archfiend cost card
- Floodgate or Field-zone disruption, noted in the guide snippet as a known choke point
Best use
Searcher/Tutor with a secondary Extra Deck extension role. Decks: Archfiend (Archfiend archetype core), Fiendsmith and Regenesis Fiend shells (co-occurring Fiend partners). Suggested copies: 2.
Evidence & gaps
- Verified: Card text: Archfiend search and Pendulum-to-Extra-Deck modes, once-per-turn limit, 1000 ATK Extra Monster Zone buff; Card type is Spell with race Field, so it is a field-zone card; Partner and archetype counts: 237 decks, 93.7% co-occurrence with Royal Archfiend, 33 distinct archetypes
- Observed: Copies per deck averaged 1.43 with 169 decks at one copy; Recorded combos average power index 4.9 with board and disruption at 0 and netCardAdvantage 0 in examples; Appears in 7 of 7 recorded combos
- Inferred: Searcher route is practical through Fiend and Archfiend shells, though not tabled in combo roles; Field-zone persistence gives multi-turn resilience and a Field-slot cost
- Data gaps: No banlist token; assumed 3 copies (unlimited) No usage statistics (StatisticsCard) for archetype inclusion; inclusion inferred from deck sample only Combo role fields (as_starter, as_searched, as_material, as_payoff, in_end_board) are all zero while appearances are 100%, so role evidence is inconsistent and unreliable No rulings data Only one guide snippet mentions the card Field-zone persistence and race Field interpretation not confirmed against card rulings
