Main 40 / Extra 3 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Twin-Headed Thunder Dragon (2800 ATK) Fusion Summoned via Polymerization or Fusion Sage, using Thunder Dragon and King of the Swamp as materials; Breaker the Magical Warrior and Kycoo the Ghost Destroyer converting a board lead into direct pressure
- Turn 1 (going first): Open Thunder Dragon or King of the Swamp with a Polymerization/Fusion Sage to reach Twin-Headed Thunder Dragon, and hold Solemn Judgment or Mirror Force for the follow-up
- Turn 2 (going second): Use Solemn Judgment, Magic Jammer, Torrential Tribute, Mirror Force or Jinzo to stop the opponent's board, then rebuild with Thunder Dragon recursion and Fusion
- Recovery: Thunder Dragon discards to search Thunder Dragon, Sangan and Fusion Sage recover the engine; Pot of Avarice and Book of Moon refill the hand
- After siding: No side deck in Master Duel; the plan is fixed for the match
Why it scores here
The deck's reliable function is interaction: 19 removal-text cards plus Solemn Judgment, Mirror Force, Torrential Tribute, Magic Jammer, Heavy Storm and Jinzo give it layered answers to most boards, which drives the highest dimension. Its engine is less dependable. Only 3 Thunder Dragons are in the Main Deck, so a Thunder Dragon in the opening five is about 34% (Inferred), and the Twin-Headed Thunder Dragon line also needs a Polymerization or Fusion Sage plus King of the Swamp as a material. Searcher text is common (74% for at least one searcher in five cards, Inferred), which helps, but 37 of 40 Main Deck copies are off the Thunder Dragon name, so the archetype does not give the deck a coherent engine. No combo boards were recorded, so the ceiling and median are text-based only. Popularity and guide coverage did not add points, and the score is not an average of card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 45 | P(≥1 Thunder Dragon in opening 5) ≈ 0.34; P(≥1 searcher in 5) ≈ 0.74; Fusion starter needs TD plus Polymerization/Sage (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | 22 level-0 spells/traps and many situational interaction cards; no hand-trap floodgate; Fusion starter dependency raises brick risk (Inferred) |
| D3 | Combo Conversion & Ceiling | 40 | Twin-Headed Thunder Dragon at 2800 ATK is the ceiling, but no recorded boards exist and the line needs multiple specific pieces (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No recorded boards to aggregate; median output is inferred from text as modest and dependent on Fusion setup (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 62 | Multiple interaction cards and searchers give several independent routes after one disruption; Thunder Dragon recursion adds continuity (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Pot of Avarice, Book of Moon and Thunder Dragon discard-search recover resources; no resource-signature data exists (Inferred) |
| D7 | End-Board & Interaction Quality | 78 | 19 removal-text cards plus Solemn Judgment, Mirror Force, Magic Jammer, Torrential Tribute and Jinzo; strong layered interaction (Inferred semantic read of card text) |
| D8 | Going-Second & Board-Breaking Power | 70 | Going-second board-breaking is supported by Solemn, Jammer, Torrential Tribute, Mirror Force and Jinzo; no going-second split data (Inferred) |
| D9 | Offensive Pressure & Closing Power | 40 | Twin-Headed Thunder Dragon 2800 ATK and Breaker/Kycoo provide pressure, but few direct closers and no piercing or direct-attack density beyond Kycoo (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 55 | 40 Main Deck cards with 31 distinct names; 24 singletons; 14% exact archetype-name purity limits coherence (Inferred from composition) |
| D11 | Extra Deck Efficiency & Coverage | 40 | Only one distinct Extra Deck card (Twin-Headed Thunder Dragon ×3) plus no alternative Extra access; limited flexibility (Verified composition) |
| D12 | Side Deck Adaptability | 20 | Master Duel has no side deck; side count is 0, so there is no post-side adaptation (Verified composition) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link or dated meta sample; archetype usage is only inferred from guides, so this is provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 60 | Fusion setup and multi-card lines with timing-sensitive traps need moderate skill; interaction sequencing is manageable (Inferred) |
How the score was computed
Strategy profile: Control primary; Toolbox secondary, disclosed; Control weights used because interaction and resources dominate. Structural ≈ 55.2, Going First ≈ 48, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: engine coherence (-3); single Extra-Deck dependency (-2); banlist exposure (-1); interaction density (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, null)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.34 · 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
- Layered interaction: removal, negation and board wipes (Solemn Judgment, Mirror Force, Torrential Tribute, Heavy Storm, Lightning Vortex, Jinzo)
- Searcher density (9 searcher-text cards) gives reasonable access to the engine
- Going-second answers are strong enough to stall boards while the engine rebuilds
Weaknesses
- Only 3 Thunder Dragons in the Main Deck, so the archetype core is rarely in the opening hand
- Low archetype purity (14%) means the engine is spread across generic staples
- A single Extra-Deck card (Twin-Headed Thunder Dragon) is the only real threat, with no alternative closer
- No side deck in Master Duel means no adaptation between games
Critical choke points
- Thunder Dragon in hand or recursion for the Twin-Headed Thunder Dragon line
- A Polymerization or Fusion Sage to access the Fusion Summon
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | One Heavy Storm | Another Thunder Dragon or a second searcher that adds a Thunder Dragon | Raises archetype core density and consistency; the Limited card is the least reliable answer in the list |
| 2 | Fissure | A second Fusion-enabling card such as an additional Fusion Sage | Gives the Fusion line redundancy without losing much interaction |
Evidence & confidence
- Verified: Main Deck 40 cards, Extra 3, Side 0, Legal in Master Duel; Heavy Storm and Solemn Judgment are Limited and run 1 copy each; Usage stats: Thunder Dragon is in 100% of archetype usage at 3 copies
- Inferred: Thunder Dragon in opening 5 ≈ 34%; searcher in 5 ≈ 74%; Layered interaction density gives strong going-second durability; Twin-Headed Thunder Dragon ceiling is text-based only
- Provisional: Meta Power is null; no dated metagame sample or tournament link; D13 matchup fit is provisional
- 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 No win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied
