Archfiend's Advent — Power Evaluation
Final Score: 59 ± 8 · Confidence: Medium
- Intrinsic: 56 · Deck: 60 · Meta: provisional
- Primary role: Board breaker / Going-second · Secondary: Boss/End-board
Why it scores here
Archfiend's Advent converts a Level 6 DARK Fiend body into a control swap: on Normal or Special Summon it takes one opponent monster until the End Phase, and the stolen monster is locked from attacking unless Shining Sarcophagus was controlled. The 2500 ATK and the 500 ATK team buff are not what earns the score; the score rests on the steal, which is a real board swing, and on its clean, single-copy deckbuilding cost. The card loses points for needing Shining Sarcophagus for its no-tribute route, for a body that is easy to negate, and for having no recorded combo data to show what it converts into in practice.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Appears in 400 of 400 sampled decks across 36 archetypes, but the no-tribute route depends on Shining Sarcophagus, and there is no starter role or searched-for role data (observed/inferred). |
| Combo & Conversion | 40 | No combo boards are recorded, so the conversion is text-only: a steal plus a team ATK buff, with no observed structural payoff (inferred). |
| Resource Economy | 25 | No card advantage or GY refuel is printed; the steal is tempo, not card gain (verified from text). |
| Effect & Interaction | 65 | Taking control of an opponent monster is a strong, hard-to-undo board swing, but it is once per turn and the stolen monster cannot attack without Shining Sarcophagus (verified from text). |
| Material Utility | 45 | A Level 6 DARK Fiend body that is usable as material for Level 6 Fiend or DARK plays, but nothing is observed as material in combos (inferred). |
| Resilience & Flexibility | 45 | The steal is a summon trigger, so a single negate removes it while the 2500 ATK body survives; no recorded multi-turn redundancy (inferred). |
| Deck-Building Efficiency | 70 | Runs one copy in 383 of 400 decks, with no garnet or brick, and no hard lock; the only restriction is the Sarcophagus dependency for the no-tribute route (observed). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Boss/End-board. Intrinsic ≈ 56, Deck ≈ 60, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Summon-triggered steal of an opponent monster is a real board swing
- Single-copy deck slot with no garnet or lock cost
- Runs in 36 archetypes; 92% of decks use gameplay type 7
- Consistent co-occurrence with Shining Sarcophagus (86.5%) supports the summon route
Weaknesses
- No-tribute route depends on Shining Sarcophagus being controlled
- Steal is once per turn and the stolen monster cannot attack without Sarcophagus
- Negating the summon trigger removes the steal, leaving a 2500 ATK body
- No combo data to confirm practical conversion
Counters / choke points
- Negating the summon effect before it resolves
- Responding to the steal trigger with a card that removes the target
- Playing around the single steal with a second threat

Evidence & gaps
- Verified: Level 6 DARK Fiend, 2500 ATK, effect monster (card text); Steal until End Phase with a no-attack restriction unless Shining Sarcophagus was controlled (card text); Once-per-turn limit on the steal effect (card text); Runs in 400 of 400 sampled decks at 1.04 average copies (deck data)
- Observed: Shining Sarcophagus co-occurs in 86.5% of decks (deck data); Single-copy in 383 of 400 decks (deck data); Archetype inclusion 67–100% across five archetypes (usage statistics; popularity, not power)
- Inferred: Board breaker role from the summon-triggered steal; Medium deck resilience from negation exposure and multi-archetype spread; Practical conversion is plausible but unconfirmed without combo data
- Data gaps: no combos supplied, so combo conversion is text-only inference no banlist token, assumed 3 copies (unlimited) no rulings or ruling-based clarifications supplied for the steal and attack restriction no top-card data ranking
