Dark Fusion — Power Evaluation
Final Score: 58 ± 6 · Confidence: Medium
- Intrinsic: 57 · Deck: 59 · Meta: provisional
- Primary role: Starter / Combo enabler
Why it scores here
Dark Fusion's value is that it turns hand and field materials into one Fusion Monster from the Extra Deck, and its deck evidence is strong: it is run in 400 of 400 sampled decks across 34 archetypes, mostly as a single copy. Its one-card conversion is capped at a single Fiend Fusion body, and the combo corpus has no recorded boards, so the conversion score rests on text. The high inclusion rate confirms the card is consistently played, not that it is intrinsically powerful, so it does not lift the score on its own. Its body is a Spell, so it earns almost nothing as material and it has no hand-trap or interaction role beyond the target protection for the summoned monster.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 72 | Run in 400/400 sampled decks and 100% of the Evil HERO usage-statistics home, with a Searcher-style partner set (Called by the Grave, Foolish Burial) confirming live access (observed). |
| Combo & Conversion | 62 | Text converts materials into one Fusion Monster from the Extra Deck; no combo boards are recorded, so the conversion is text-only (inferred). |
| Resource Economy | 50 | Uses one card to produce one Fusion Monster and sends materials to the GY, so it is roughly card-neutral with no recorded refuel or net advantage (inferred). |
| Effect & Interaction | 35 | Its only interaction is that the summoned monster cannot be targeted by opponent card effects this turn, which is soft protection (verified). |
| Material Utility | 10 | It is a Spell and cannot be used as material, so the score reflects only the absence of a material body (verified). |
| Resilience & Flexibility | 30 | A Spell that can be stopped by spell-negating responses, and its value depends on having Fusion materials and an Extra Deck target (inferred). |
| Deck-Building Efficiency | 72 | Average 1.25 copies per deck (337 of 400 run one), with no garnet or lock restriction beyond the Fiend-only Fusion target (observed). |
Calculation
Weight profile: Starter / Combo enabler profile applied alone; no secondary blend. Intrinsic ≈ 57, Deck ≈ 59, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Included in 400/400 sampled decks across 34 archetypes, so it has a wide home base
- Central Fusion enabler for Fusion-based decks, with strong observed partner support (Evil HERO Adusted Gold 90%, Ash Blossom 75.5%)
- Summoned monster is protected from opponent card effects this turn
Weaknesses
- Text restricts the Fusion Monster to Fiend, which limits which Extra Deck targets it can reach
- Contributes no body of its own and does not act as material
- No recorded combo boards, so conversion strength is unverified
Counters / choke points
- Spell-negating responses to its activation (inferred)
- Opponent interaction that stops the Fusion Summon itself (inferred)
Best use
Starter / Fusion enabler. Decks: Heroic, Yubel, Fiendsmith, Infernoid, Phantom Beast (Chimera), Evil HERO. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: Fusion Summon 1 Fiend Fusion Monster from Extra Deck using hand/field materials; the summoned monster cannot be targeted by opponent card effects this turn; Run in 400/400 sampled decks; average 1.25 copies (337 decks run 1 copy); Present in 34 distinct archetypes
- Observed: Evil HERO usage-statistics inclusion 100% at 2 copies; Heroic archetype: 135 decks (33.8%); Top partner co-occurrence: Evil HERO Adusted Gold 90%, Evil HERO Sinister Necrom 76.8%, Ash Blossom & Joyous Spring 75.5%
- Inferred: Acts as a Fusion enabler that converts materials into one Fusion body; Spell-negation responses can stop its activation; Card is roughly card-neutral because materials go to the GY
- Data gaps: No combo boards supplied: combo conversion is text-only inference No banlist token; assumed 3 copies (unlimited) No ruling or metagame sample to confirm timing or current standing Recursion-style or refuel effects are not evidenced because none are in the text
