Thunder Dragon Deck #745154 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Stun
• Format: master-duel

Legality

Main 42 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fusion Summon Level 8+ boss monsters (Thunder Dragon Fusion, Albion, Lubellion, Dragon that Devours the Dogma) off a Thunder Dragon / Bystial / Branded / Albaz starter, then attack or banish through the board; Bystial and Thunder Dragon 2500-ATK beatsticks from the Deck via banish-revival effects
• Turn 1 (going first): Open a starter (Thunder Dragon, Thunder Dragondark, Batteryman Solar, Bystial Druiswurm; ~99.65% chance of at least one archetype-core card in hand of 5) and extend into a Fusion Summon through the Branded or Albaz route
• Turn 2 (going second): Hold Ash Blossom, Maxx C and Forbidden Droplet (about 37.8% chance of at least one hand trap in 6 cards) to answer the opponent's first summon, then rebuild through Fusion from the field and GY
• Recovery: Recover from the Deck and GY with the Thunder Dragon searchers (Thunder Dragondark, Thunder Dragonroar, Thunder Dragon Fusion, Blazing Cartesia) and the Bystial banish-revival effects
• After siding: Not evaluable: the export has no Side Deck (Side Deck size 0), so there is no sideboard plan

Why it scores here

The deck is Illegal: The Fallen & The Virtuous is run three times against a Semi-Limited limit of two, so it receives no normal Final Contextual score and is capped at 30 as a theoretical, structural-only read. Its engine is reliably accessible: the archetype-core set (27 copies) has a 99.65% chance of at least one card in a 5-card opening hand, and the searchers give a high chance of recovering a starter. Conversion is weak on the recorded evidence, with a best recorded board of 8, a median of 7, and five combos of which none were tagged as going-first or going-second. The 40-card-plus list mixes four sub-archetypes (Thunder Dragon, Bystial, Branded, Albaz) with 21% exact-name purity, so consistency rests on system coherence rather than on card scores. Popularity and archetype usage confirm the list is real and accessible but earned no points, and no side deck, win-rate, or meta data exists to lift Meta or Tournament Reliability.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 51, Going First ≈ 55, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: illegal_copy_limit_cap (0). Final formula: Structural 51 = Combo profile (sum of dimension x weight / 100 = 50.66). Unconstrained 0.80*51 + 0.20*48 = 50.4, then capped at 30 because the deck is Illegal (copy-limit violation). Theoretical/structural-only; Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex 8, median 7, board-per-starter 0
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Engine is highly accessible: archetype-core cards have a 99.65% chance of appearing in an opening hand of 5
• Dense searcher suite (14 searcher-text cards) supports recovery and consistency
• Boss options at 2500 to 3200 ATK and a varied Fusion route set (Branded, Albaz, Thunder)

Weaknesses

• Illegal: Fallen & The Virtuous is over its copy limit, so the list cannot be played as built
• Four sub-archetypes with 21% exact-name purity dilute engine coherence
• Recorded combos peak at a power index of 8 with a median of 7; no recorded going-second lines
• No Side Deck, so there is no post-side plan

Critical choke points

• Fusion Summon access depends on Fallen of Albaz (1 copy) or Fallen of the White Dragon (2 copies) as a material
• Thunder Dragon Fusion and the Branded Fusion / Gold Sarcophagus route each depend on a single copy

Recommended changes

Evidence & confidence

• Verified: Illegal: The Fallen & The Virtuous 3 copies vs Semi-Limited limit 2; Main 42 (within 40-60), Extra 15 (within 0-15), Side 0; Archetype-core P(>=1 in hand of 5) = 0.9965; Five recorded combos, best index 8, median 7
• Observed: Recorded combo PowerIndex range 2 to 8; Average end hand 2.2 and zero recorded GY/banish use
• Inferred: Engine accessibility 72 and consistency 60 from hypergeometric estimates and copy histogram; Interaction quality 55 from card text (removal 13, negation 5, hand traps 3); Pilotability 45 from multi-step Fusion and banish chains
• Provisional: Meta Power (null: no dated meta sample); Matchup and format fit 50 (no tournament or win-rate data); Side deck adaptability 20 (no Side Deck in export)
• Data gaps: Illegal copy-limit violation: The Fallen & The Virtuous 3 vs limit 2; score capped usage statistics conflicts with the card list: Thunder Dragon Colossus (2), Thunder Dragon Titan (1), Chaos Angel (1) and S:P Little Knight (1) appear in the Extra Deck, but usage marks them in this deck false; likely an id mismatch No Side Deck in export (Side Deck size 0): no post-side plan or D12 evidence No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry (going-first/second, matchup, brick, starter, OTK rates) Five combos, all gameplay unknown, none going-first or going-second; combo evidence is thin Deck title is null
