Thunder Dragon Deck #760610 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Control
• Format: ocg

Legality

Main 57 / Extra 0 / Side 0 — status: Illegal. 5 violation(s).

Identity & game plan

• Win condition: No reliable win condition; the deck converts through Thunder Dragon searches plus removal, negation and disruption trading into a late board of Black Luster Soldier, Jinzo or Chaos Sorcerer, which are single copies and not a repeatable plan.; Attrition through Trap and Spell removal (Mirror Force, Torrential Tribute, Lightning Vortex, Dust Tornado) and Card Destruction-style card parity.
• Turn 1 (going first): Open Thunder Dragon (P(at least one in 5 cards) ~0.24) to search a second Thunder Dragon, then hold traps and removal. Reliability is low because the deck has 23 monsters against 34 Spells and Traps.
• Turn 2 (going second): Hold Mirror Force, Torrential Tribute and the removal spells in hand and react to the opponent's first board. The deck has no hand traps and no Extra Deck, so the going-second plan depends on draws.
• Recovery: Recover through Sinister Serpent, Sangan and Gravekeeper's Spy recursion or search, plus removal to clear blockers. Recovery is slow and card-hungry.
• After siding: Not evaluable: the deck has no side deck, so there is no post-side plan in the export.

Why it scores here

The deck is Illegal, with five copy-limit violations including four Forbidden cards (Trap Dustshoot, Delinquent Duo, Pot of Greed, Graceful Charity) and Solemn Judgment at 3 copies against a limit of 1, so it receives a capped, structural-only score rather than a normal Final Contextual score. The structural read is that the deck is a Toolbox-style pile of removal, negation and card draw around three Thunder Dragon, with its interaction density (roughly 32 removal-text cards) as its clearest strength. Engine access is weak: P(at least one Thunder Dragon in an opening 5) is about 0.24, and with 34 Spells and Traps against 23 monsters the brick risk is high. The Extra Deck is empty and there is no side deck, so the deck has no late-game threat, no going-second route beyond draws, and no post-side plan. Popularity and archetype naming did not earn points: the Thunder Dragon exact-name purity is only 5.3%, and the usage core cards (Mulcharmy Fuwalos, Thunder Dragon Colossus, Harpie's Feather Duster) are absent. Dimension scores were set on the system, not averaged from card scores.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 38, Going First ≈ 34, Going Second ≈ 30, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist exposure (-12). Final formula: Structural 38 and TournamentReliability 30 give 0.80*38 + 0.20*30 = 36 before modifiers; banlist-exposure modifier -12 gives 24; Illegal cap sets the final score to 20. Theoretical/structural-only, not a normal Final Contextual score.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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 removal and negation suite (about 32 removal-text cards, Mirror Force, Torrential Tribute, Lightning Vortex, Heavy Storm)
• Three Thunder Dragon with searcher text provides some consistency for the archetype

Weaknesses

• Illegal list: five copy-limit violations, four Forbidden cards
• No Extra Deck and no side deck
• Only 23 monsters against 34 Spells and Traps, so brick and dead-draw risk is high
• Archetype purity 5.3%; the Thunder Dragon core is thin
• No win condition beyond single-copy monsters

Critical choke points

• Thunder Dragon starter access (about 0.24 in an opening 5)
• Legality: any build that keeps Forbidden or over-limit cards is not playable as listed

Recommended changes

Evidence & confidence

• Verified: Five copy-limit violations (four Forbidden, Solemn Judgment at 3 copies against 1); Main Deck 57 cards, Extra 0, Side 0; size rule for OCG is 40-60 Main, 0-15 Extra/Side; Card texts for the 57 distinct cards; Usage stats: Thunder Dragon 52% inclusion; Mulcharmy Fuwalos, Thunder Dragon Colossus, Harpie's Feather Duster absent
• Inferred: Starter access probability (hypergeometric); Brick rate from monster-to-spell/trap ratio; Interaction quality from card text; Pilotability from decision-point count
• Provisional: Meta Power (no dated meta sample); Matchup and format fit
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only No tournament link; archetype meta-share and per-pilot records absent No win-rate telemetry for going-first, going-second, matchups or brick rate No side deck, so post-side behaviour is unknown Meta Power provisional unless a dated metagame sample is supplied
