Legality
Main 30 / Extra 9 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Assemble a D/D/D Extra Deck board (Abyss King Gilgamesh into Pendulum scales, then Deus Machinex / Siegfried / Caesar Ragnarok) and convert the ATK advantage into an OTK.; Grind with recurring D/D monsters (Genghis revival, Necro Slime grave-fusion, Abyss Ragnarok Pendulum revival) while Dark Contracts out-advantage the opponent.
- Turn 1 (going first): Open Dark Contract with the Gate or Copernicus/Kepler/Gryphon, Link Summon Abyss King Gilgamesh to place two D/D Pendulum scales from Deck, then Pendulum Summon into Deus Machinex or Siegfried with one piece of interaction held.
- Turn 2 (going second): Break the board with Forbidden Droplet and D/D/D Headhunt, then push with high-ATK Fusions (Caesar Ragnarok 3200, Beowulf 3000) and Pendulum Summoned bodies for lethal.
- Recovery: Rebuild through Graveyard fusion (Necro Slime, Swamp King), Genghis revival triggers, Abyss Ragnarok's Pendulum revival and Machinex's Pendulum Zone swap.
- After siding: Duel Links uses no side deck; adaptation happens through Main Deck ratios only (hand-trap and Droplet counts), not a transformational side plan.
Why it scores here
The deck is scored as a system, not as an average of its card scores, and the archetype's popularity earns it nothing on its own. What earns points is the engine's accessibility: Dark Contract with the Gate at three copies plus Copernicus, Kepler and Gryphon give roughly a 0.89 chance of opening at least one search-text card, and Abyss King Gilgamesh converts two bodies into a full Pendulum setup, so the deck usually opens something real. What holds the score near the mid-60s is everything after the opener: twelve singleton slots mean the median board is one boss plus one interaction rather than the ceiling board, and no recorded combo evidence exists to prove a higher floor. Interaction is functional at Duel Links scale (Siegfried's Spell/Trap negate, Deus Machinex removal, Headhunt stealing, Droplet and Ghost Belle) but thin and narrow, and every extra Dark Contract stacks 1000-point Standby Phase damage in a 4000 LP format, which is a real loss vector. Piloting burden is high and error tolerance low, and with no dated metagame sample Meta Power stays provisional, so the final number reflects a strong Duel Links engine with a moderate median and a fragile self-damage axis.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 76 | P(≥1 searcher-text card in a 5-card hand) ≈ 0.89 with Gate ×3, Copernicus ×3, Kepler ×2 and Gryphon ×3, but most lines still want a second card (Inferred). |
| D2 | Opening-Hand Quality & Brick Management | 68 | Only 7 of 30 Main Deck cards are non-D/D engine, so all-engine hands are rare; the real risk is twelve singleton slots producing low-ceiling hands plus stacked Dark Contract self-damage (Inferred). |
| D3 | Combo Conversion & Ceiling | 75 | No recorded boards exist; the text-read ceiling is Gilgamesh into double Pendulum scale then Deus Machinex or Siegfried at 2800-3000 ATK with one negation and one removal (Inferred). |
| D4 | Combo Floor & Median Output | 62 | Median is inferred at one boss plus one interaction because twelve of nineteen Main Deck names are one-ofs and combos_evidence contains zero scored boards (Inferred). |
| D5 | Interruption Resilience & Route Redundancy | 66 | Independent entry points span Gate, Copernicus, Kepler, Gryphon, Orthros and the Slime package, with recursion through Necro Slime, Genghis and Abyss Ragnarok (Inferred). |
| D6 | Resource Economy, Recovery & Grind | 62 | Dark Contracts are repeatable advantage engines but each bleeds 1000 LP per Standby Phase in a 4000 LP format; no resource_signature or netCardAdvantage data was supplied (Inferred). |
| D7 | End-Board & Interaction Quality | 64 | Interaction is Siegfried's Spell/Trap effect negate, Deus Machinex/Witch removal, Headhunt's control steal, plus Droplet ×2, Ghost Belle and Lancea — broad enough but each piece is narrow (Inferred). |
| D8 | Going-Second & Board-Breaking Power | 65 | Going-second tools are limited to Forbidden Droplet ×2, Headhunt and Caesar Ragnarok's equip-drain; no going-second combo split exists in the evidence to confirm it (Inferred). |
| D9 | Offensive Pressure & Closing Power | 74 | Caesar Ragnarok 3200 ATK, Deus Machinex and Beowulf at 3000 ATK, Beowulf's piercing and Abyss Ragnarok revival give genuine closing pressure (Inferred). |
| D10 | Main Deck Efficiency & Flexibility | 66 | 30 cards over 19 distinct names with 12 singletons; every card is searchable through Gate or Kepler, but the one-of spread caps redundancy and raises dead-card risk (Inferred). |
| D11 | Extra Deck Efficiency & Coverage | 72 | All 9 Extra slots are used across Link/Fusion/Synchro/Xyz with Gilgamesh and Machinex as 2-ofs, though Number 68: Sanaphond the Sky Prison (100% archetype inclusion) is absent (Verified stat, Inferred read). |
| D12 | Side Deck Adaptability | 50 | Duel Links runs no side deck (side_count 0), so post-side adaptation does not exist as a dimension in this format (Verified). |
| D13 | Matchup Coverage & Format Fit | 60 | No tournament link and no dated metagame sample were supplied, so format fit is provisional rather than measured (Provisional). |
| D14 | Pilotability & Error Tolerance | 45 | D/D/D lines require Pendulum scale ordering, Dark Contract damage accounting and multi-Summon sequencing with many decision points and little room for error (Inferred). |
How the score was computed
Strategy profile: Combo. Structural ≈ 67.6, Going First ≈ 64, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: Dark Contract self-damage exposure (-3); Archetype core completeness (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.89 · key two-card combo ≈ 0.7 · full-brick estimate ≈ 0.04 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Very high starter density for a 30-card Duel Links deck: Gate ×3 plus Copernicus/Kepler/Gryphon means a live opener in roughly nine of ten hands (Inferred)
- Abyss King Gilgamesh converts any two D/D bodies into a full Pendulum setup, making the engine's payoff accessible from many openings
- Strong closing power for the format — 3200 ATK Caesar Ragnarok and 3000 ATK Deus Machinex/Beowulf with piercing
- Real recursion: Necro Slime Graveyard fusion, Genghis revival triggers, Abyss Ragnarok Pendulum revival and Machinex's Pendulum Zone swap
- Extra Deck covers Link, Fusion, Synchro and Xyz with two 2-of boss slots instead of spreading thin
- List matches roughly 23 of 25 archetype-standard cards, so it is a legitimate build rather than a budget shell
Weaknesses
- Twelve singleton Main Deck slots give a low median board; the ceiling line is not what the deck usually produces
- Stacked Dark Contract upkeeep (1000 LP each Standby Phase) is a self-inflicted loss vector in a 4000 LP format
- Interaction is narrow: Siegfried only negates face-up Spell/Trap effects, and removal answers are one-of situational cards
- Going-second breaking is thin — Droplet ×2 plus Headhunt are the only real board-breaking tools
- Number 68: Sanaphond the Sky Prison and Droll & Lock Bird are flagged as 100%-inclusion archetype cards but are missing here
- Piloting burden is high; ordering Pendulum scales, Contract damage and Summon sequencing punishes small errors
Critical choke points
- Abyss King Gilgamesh resolution — if the Link Summon or its Pendulum-placement effect is stopped, most two-card openings collapse to a single body
- Copernicus/Kepler Normal Summon being negated removes the deck's main one-card bridge and leaves the hand reliant on Gate
- Graveyard access: Necro Slime and Swamp King lines fold to Graveyard hate, which the deck itself is aware of given Lancea ×3
- Extra Deck ceiling: only two Gilgamesh and two Machinex copies, so repeated disruption of one boss leaves no third copy to fall back on
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 1x D/D/D Deviser King Deus Machinex (second copy) | 1x Number 68: Sanaphond the Sky Prison | Usage stats list Sanaphond at 100% archetype inclusion and it is absent here; trimming the redundant second Machinex keeps both bosses represented without losing coverage. |
| 2 | 1x Artifact Lancea | 1x Droll & Lock Bird | Archetype usage statistics show Droll & Lock Bird at 100% inclusion at three copies while Lancea is not part of the standard shell; three Lancea in a 30-card deck is a heavy tax on engine space. |
| 3 | 1x D/D Dog | 1x D/D/D Oblivion King Abyss Ragnarok | Usage stats show Abyss Ragnarok at a typical two copies; a second copy raises the consistency of the Pendulum revival line that carries the grind plan. |
| 4 | 1x Mulcharmy Purulia | 1x Forbidden Droplet | Droplet is the deck's only scalable board-breaker and is a three-of in the archetype standard; Purulia competes for the same reactive slot with less impact going second. |
| 5 | Consider converting 2-3 singleton flex slots | Additional copies of core D/D names | Cutting singleton count would lift the median board, which is the binding constraint on this build's score. |
Evidence & confidence
- Verified: Legality: 30 Main / 9 Extra / 0 Side, no violations and no restricted cards under BanDuelLink; Card text and banlist status for all 26 distinct cards are present and resolved; Usage statistics: 25 archetype stat rows with inclusion percentages and typical copy counts; Duel Links format has no side deck (side_count 0)
- Observed: composition spreads: 14 Pendulum monsters, 7 Dark Contract Spell/Trap cards, 4 hand-trap-flagged cards; probabilities.searcher_text_group = 10 copies giving P(≥1 in 5 cards) ≈ 0.8912
- Inferred: P(functional opener) ≈ 0.89 and P(two-card line) ≈ 0.70 from hypergeometric estimates over the 30-card list; Median board of one boss plus one interaction derived from the twelve-singleton distribution; Ceiling board of Gilgamesh → Pendulum scales → Machinex/Siegfried read from card text, not from recorded boards; Going-second power derived from Droplet/Headhunt/Caesar Ragnarok text rather than a going-second combo split
- Provisional: Matchup coverage and format fit — no tournament link and no dated metagame sample; Tournament reliability — no win-rate, brick-rate or starter-rate telemetry exists in YGOVN
- Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied usage_statistics in_this_deck flags conflict with the resolved cards list for the Extra Deck monsters (e.g. Deus Machinex and Gilgamesh are listed with copies in the deck but flagged absent) — the cards list was treated as source of truth
