Thunder Dragon Deck #771292 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 34/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Extra Deck fusion beaters (Master of Oz 4200 ATK, Twin-Headed Thunder Dragon 2800 ATK, Gatling Dragon 2600 ATK) backed by a generic removal and trap suite; Gatling Dragon's coin-toss board wipe and Torrential Tribute / Ring of Destruction as sweepers when the opponent commits
• Turn 1 (going first): Open with Thunder Dragon or a searcher (Sangan, Sinister Serpent, Thunder Dragon) to find a second Thunder Dragon and fuse into Twin-Headed Thunder Dragon; hold removal traps for the opponent's first attack
• Turn 2 (going second): Use Mirror Force, Sakuretsu Armor, Dust Tornado and Raigeki Break to clear the opponent's first board, then rebuild with Upstart Goblin or Jar of Greed draws and fusion
• Recovery: Draw effects (Dekoichi, Jar of Greed, Upstart Goblin) and searchers (Magician of Faith, Sinister Serpent) refill the hand; recovery depends on fusion material availability in the GY and hand
• After siding: Not evaluable: the deck runs no side deck (side count 0), so there is no post-side plan

Why it scores here

The score is a structural read of the list as submitted, capped low because the deck is illegal: four Forbidden cards (Trap Dustshoot x3, Delinquent Duo, Pot of Greed, Graceful Charity) exceed their copy limit of zero, so the result is theoretical only. The system reliably offers interaction density, with Raigeki Break, Sakuretsu Armor, Mirror Force, Torrential Tribute, Ring of Destruction and Gatling Dragon providing layered removal, which drives the highest dimension (D7). Engine access is the weak point: Thunder Dragon runs only 3 copies with about 25% odds of at least one in the opening five, the archetype purity is 5.7% (exact-name), and the 15 Fusion monsters are spread across many unrelated archetypes, so there is no single reliable starter. No combos, tournament data or win-rate telemetry exist, so the ceiling and floor are text-only inferences. Popularity and archetype usage were not credited, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 47.8, Going First ≈ 45, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: banlist exposure (Forbidden cards over limit) (-10); no side deck / weak post-side plan (-2). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*47.8 + 0.20*38 = 45.8, then context modifiers -12 (total), giving 33.8 rounded to 34. Illegal-deck cap applied: theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 interaction suite (Mirror Force, Torrential Tribute, Ring of Destruction, Gatling Dragon)
• Real Extra Deck closing power: Master of Oz, Black Luster Soldier Envoy and Twin-Headed Thunder Dragon
• Strong draw and search density for recovery once the deck is legal (after removing forbidden cards)

Weaknesses

• Illegal list: four Forbidden cards exceed the copy limit
• Weak archetype coherence: 5.7% exact-name purity and 15 Fusion monsters from many archetypes
• No side deck, so no best-of-3 adaptability
• No hand traps or floodgates against a fast opponent

Critical choke points

• Thunder Dragon engine: only 3 copies, about 25% odds of at least one in the opening five
• Fusion materials must be present in hand or GY before Extra Deck threats are reachable
• Trap Dustshoot, Pot of Greed and Graceful Charity are illegal, so their slots are dead until replaced

Recommended changes

Evidence & confidence

• Verified: Four Forbidden cards over the copy limit make the deck Illegal in OCG; Main 55, Extra 15, Side 0; Main and Extra sizes are within the OCG size rules; Thunder Dragon archetype purity is 5.7% (exact name); Thunder Dragon Colossus is a missing usage-core card; Card text confirms removal density (about 24 removal-text cards) and searcher density (7 searcher-text cards)
• Inferred: Starter consistency: P(at least 1 Thunder Dragon in opening 5) ≈ 0.25; searcher group ≈ 0.51; Brick risk from fusion-material dependence and off-archetype Fusion monsters; Interaction quality and closing power read from card text and stats, not from recorded play
• Provisional: Tournament reliability and format fit (no tournament link, no win-rate telemetry); Meta power is null: no dated metagame sample supplied
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no side deck: post-side plan unevaluable no win-rate telemetry exists in YGOVN for this deck Meta Power is Provisional unless a dated metagame sample is supplied deck title is null, so the deck is identified only by its archetype and id
