Legality
Main 30 / Extra 9 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Extra Deck boss monsters (D/D/D Beowulf, Caesar, Deus Machinex, Gilgamesh) summoned through Fusion, Xyz, Link and Synchro lines built off the Pendulum Zones and the Graveyard; Pendulum-Scale-driven board control with D/D Gryphon, D/D Dog and D/D Orthros, backed by Dark Contract with the Gate searches
- Turn 1 (going first): Search with Dark Contract with the Gate or Savant Kepler, set Pendulum Scales, and start a Fusion, Xyz or Link summon from the Swirl Slime or Necro Slime engine
- Turn 2 (going second): Use Forbidden Droplet, D/D Dog, Copernicus or Headhunt to negate or destroy the opponent board, then rebuild a boss from the Graveyard or hand
- Recovery: Re-search through the Gate and Zero Laplace, and use Necro Slime and Swirl Slime to re-fuse from the Graveyard or hand
- After siding: Not applicable: Duel Links has no Side Deck, so the deck cannot adapt between games
Why it scores here
The deck reliably opens a searcher-driven starter: the three Dark Contract with the Gate copies give about a 0.92 chance of at least one searcher in a 5-card opening hand (Inferred), and the Pendulum starters give several independent routes into the Extra Deck. Its ceiling is high because nine Extra Deck slots spread across Fusion, Xyz, Link and Synchro offer many boss options from one engine, but the recorded-combo floor and median are unknown because the export carries no parseable boards, so those scores are text-based inference. Interaction is dense (10 negation-text cards, 15 removal-text cards, two hand traps), which supports going second, while the recurring 1000-damage cost of the Gate and the Pendulum scale conflicts limit recovery. Popularity and guide tier-1 claims earned no points, and the score is built from consistency, median output and interaction on the system, not from averaging the individual card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 68 | P(at least 1 Gate or Kepler in 5 cards) ≈ 0.43 each; P(at least 1 searcher in 5) ≈ 0.92; 2-card bootstrap via Gate plus Pendulum (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 62 | 11 searchers and 10 negation cards make most hands functional, but Mulcharmy and Witch are off-plan dead-card risks in some hands; no brick estimate computed (Inferred) |
| D3 | Combo Conversion & Ceiling | 70 | 9 Extra Deck options across Fusion, Xyz, Link and Synchro give a strong ceiling; no recorded boards to measure board_per_starter (Inferred semantic read) |
| D4 | Combo Floor & Median Output | 58 | Median output cannot be measured: combos_evidence has 0 parseable boards, and the guides describe Turn 1 OTK only as a best case (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Seven distinct Pendulum and Slime starters give independent routes after one disruption, but the Gate's damage and Dark Contract with the Witch's cost reduce recovery (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Gate and Necro Slime provide regeneration, but each Standby Phase Gate effect costs 1000 life; Graveyard recursion is text-only (Inferred) |
| D7 | End-Board & Interaction Quality | 68 | 10 negation-text and 15 removal-text cards, plus 2 hand traps and Forbidden Droplet's ATK halving and negation text (Verified text plus Inferred quality) |
| D8 | Going-Second & Board-Breaking Power | 62 | Droplet, Dog, Headhunt and Copernicus cover going-second interaction, while the Extra Deck bosses supply board-breaking ATK (Inferred; no going-second split recorded) |
| D9 | Offensive Pressure & Closing Power | 66 | Boss ATK reaches 3000 and 3200 (Beowulf, Caesar, Deus Machinex) with Pendulum and Fusion piercing text; closing depends on resolving the summon chain (Verified stat, Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 62 | 30 main cards at the 30-card cap, 19 distinct, with 12 singletons and 7 three-copy cards; dense but near the size ceiling (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 72 | Nine Extra Deck cards cover four summon types with 2 Gilgamesh and 2 Deus Machinex for redundancy; several bosses need specific materials (Inferred) |
| D12 | Side Deck Adaptability | 40 | No Side Deck exists in Duel Links, so adaptability is structurally absent and scored neutral-low (Verified rule, Provisional) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link and no dated meta sample, so format fit is unknown (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Many branching Pendulum, Fusion-from-GY and Link decisions with several per-turn once-limits make the deck demanding to pilot (Inferred from text) |
How the score was computed
Strategy profile: Combo. Structural ≈ 62.7, Going First ≈ 64, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*62.7 + 0.20*56 - 2 = 59.4 -> 59
Probability & combo summary
- Opening a starter: P(≥1) ≈ — · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Dense searcher density (11 searchers, about 0.92 at least one in a 5-card hand)
- Nine Extra Deck slots across four summon types give multiple boss routes
- Interaction-heavy main deck with 10 negation and 15 removal text cards
- Legal with no copy-limit violations
Weaknesses
- No recorded boards, so floor and median output are unmeasured
- Gate's 1000-damage cost each Standby Phase
- No side deck to adapt between games
- Off-plan cards (Mulcharmy, Droll, Dark Contract with the Witch) can dilute the engine
Critical choke points
- Savant Kepler, Gate and Zero Laplace as the only searchers for the first hand
- Gilgamesh as the Link material enabler for the Extra Deck chain
- Necro Slime or Swirl Slime in the Graveyard or hand as the re-fusion route
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Mulcharmy Fuwalos | A second D/D/D Extra Deck boss or a D/D searcher | Off-archetype copies cost hand space and do not continue the Pendulum or Extra Deck lines (Inferred) |
| 2 | Dark Contract with the Witch | Dark Contract with the Swamp King or Dark Contract with Patent License | Witch's destruction is narrower than a Fusion-enabling starter; other Dark Contracts keep the engine running (Inferred) |
Evidence & confidence
- Verified: Legal in Duel Links: 30 main (cap 30), 9 extra (cap 9), 0 side; All 19 distinct main and 7 distinct extra cards are Unlimited with no copy violations; Searcher-text count 11, negation-text count 10, removal-text count 15 from card text
- Inferred: Searcher hand probability 0.92 and single-card hand probabilities 0.43 and 0.37 (hypergeometric); Going-second interaction density and Extra Deck boss power ceiling from card text; Brick and engine-conflict risk from composition
- Provisional: Meta Power and format fit (no dated meta sample); Tournament reliability (no tournament link); Side-deck adaptability (no side deck exists)
- Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent usage_statistics in_this_deck flags read false for Extra Deck cards (Siegfried, Beowulf, Caesar, Genghis, Tell, Gilgamesh, Deus Machinex) even though the cards list shows them in the extra zone; the 70.8% core-present figure therefore understates the list and was not used no win-rate telemetry: going-first, going-second, matchup and OTK rates are unknown Meta Power is Provisional unless a dated metagame sample is supplied
