Forbidden Dark Contract with the Swamp King — Power Evaluation
Final Score: 53 ± 6 · Confidence: Medium
- Intrinsic: 49 · Deck: 56 · Meta: provisional
- Primary role: Starter / Combo enabler · Secondary: Extender
Why it scores here
The card's text converts a hand or field monster into a negated D/D/D body each turn and then Fusion Summons a Fiend Fusion from the Extra Deck, so it is a real engine piece inside its own deck. It is played in all 51 sampled decks at an average of 1.8 copies, which confirms it is run consistently but does not by itself raise its power. The mandatory 2000-damage Standby drain, the Continuous Spell's exposure to removal, and its dependence on the D/D/D shell pull the score down, and its high deck count is not counted as strength.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Playable from hand as a Spell and present in all 51 sampled decks at 1.8 copies on average, but no searcher or starter data exists to show how often it is drawn (observed/inferred). |
| Combo & Conversion | 60 | The text chains a negated D/D/D Special Summon into a Fiend Fusion Summon in one card, and top partners such as D/D Savant Kepler appear in about 63% of decks, though no recorded board confirms it (inferred). |
| Resource Economy | 35 | Fusion Summoning from the Extra Deck is card-neutral, but the mandatory 2000-damage Standby drain is a steady life cost with no card return (verified). |
| Effect & Interaction | 10 | The card has no negate, removal, or hand-trap effect, so it offers no opponent interaction (verified). |
| Material Utility | 25 | As a Spell it is not a material body itself; its negated D/D/D summon is a material that still counts as material even when blanked, but this is inferred from text (inferred). |
| Resilience & Flexibility | 40 | A Continuous Spell is removed by standard spell removal, but its once-per-turn effects stay live across turns once it is on the field (inferred). |
| Deck-Building Efficiency | 55 | Copy counts spread across 1 to 3 copies with no garnet or lock text, though the 2000 LP drain and D/D/D dependence add some deck-building cost (observed/verified). |
Calculation
Weight profile: 0.7 Starter / Combo enabler + 0.3 Extender. Intrinsic ≈ 49, Deck ≈ 56, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Chains a negated D/D/D Special Summon into a Fiend Fusion Summon from one card
- Played in all 51 sampled decks across 13 archetype labels with no garnet cost
- Once-per-turn effects stay live across turns while it remains on the field
Weaknesses
- Mandatory 2000-damage Standby drain every turn it stays on the field
- Continuous Spell is exposed to standard spell removal
- Fusion target must be a Fiend-type Fusion from the Extra Deck, so it depends on Fusion support
- Its value sits mostly inside the D/D/D shell rather than in any generic role
Counters / choke points
- Continuous Spell removal or negation (inferred, no combo evidence)
- Opponent-side disruption on the D/D/D monsters it needs (inferred)
Best use
Starter / Fusion enabler inside D/D/D. Decks: D/D/D, D/D/D (D.D.). Suggested copies: 2.
Evidence & gaps
- Verified: Card text: once-per-turn negated D/D/D Special Summon from hand, once-per-turn Fiend Fusion from Extra Deck, mandatory Standby 2000 damage; Present in 51 of 51 sampled decks at 1.8 copies on average
- Observed: Top partners co-occur in 49-65% of decks; Usage statistics show 100% inclusion in the Toon archetype at 3 copies
- Inferred: Converts a negated D/D/D body into material value; Consistent inclusion reflects role, not intrinsic power
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited)
