Thunder Dragon Deck #761328 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Midrange, Fusion/Link
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Fusion or Link Summon a large Thunder Dragon board (Thunder Dragon Titan 3200/3200, Thunder Dragon Colossus 2600/2400, Thunder Dragonthunderstormech 2800) off repeated Thunder Dragon searches.; Perfectron Hydradrive Dragon (5000 ATK, 1 copy, Limited) or Albaz/Lubellion fusion chain via Fallen of Albaz, which is a single-copy starter.
• Turn 1 (going first): Opening hand searches for Thunder Dragon engine (searcher text in 19 cards, P(>=1 in 5) = 0.97), then a fusion or link into the 3-copy Thunder Dragon core. Single-copy Albaz/Bystial pieces are not reliable on T1.
• Turn 2 (going second): Six-card hand with 8 hand traps (P(>=1 in 6) = 0.76) to answer the opponent's first board, then rebuild through Thunder Dragon recursion from GY and banish.
• Recovery: Thunder Dragon monsters recur from GY and banish (Thunderstormech, Dragonhawk, Dragonmatrix), and Lightning Crash, Thunder Dragon Fusion and the searchers restock the hand.
• After siding: None. The deck runs 0 side cards, so there is no post-side plan.

Why it scores here

This is a structural read of an illegal list, so the score is capped. The deck's engine is dense: 19 searcher-text cards give a 0.97 chance of at least one searcher in an opening five, and the three-copy Thunder Dragon core converts into large fusion and link boards. Its consistency is weak: only 34.5% of main-deck copies are exact Thunder Dragon, the Bystial, Branded, Batteryman, Albaz and Kuriboh pieces are mostly single copies, and the starter probability for the core is only about 0.34. Interaction is the strongest part of the deck, with 8 hand traps and 6 negation texts, but no combo boards were recorded, so the floor, median and ceiling are text inference only. Popularity did not earn points: the archetype has 1 of 4 core cards present and no tournament record. Cross-Sheep and Albion are Forbidden and make the list Illegal, so no normal Final score is awarded and the score is capped at 30. The scores were built per dimension on the system and not averaged from card scores.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Midrange secondary (approx. 2:1 by reasoning; deck has no combo boards to confirm). Structural ≈ 54, Going First ≈ 50, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (Forbidden cards run) (-12); illegal-deck cap (-9.5). Final formula: 0.80*Structural(54.4) + 0.20*TournamentReliability(40) = 51.5, then -12 banlist-exposure modifier = 39.5, then capped at 30 because the deck is Illegal (Forbidden cards Albion and Cross-Sheep). Meta is provisional and excluded.

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

• Dense searcher text (19 cards) gives near-certain access to some Thunder Dragon engine piece in the opening hand
• Eight hand traps and six negation texts give layered interaction on both turns
• Fusion and link ceiling is high (Titan 3200, Colossus 2600, Thunderstormech 2800, Perfectron 5000)
• Thunder Dragon monsters recur from GY and banish, which helps recovery

Weaknesses

• Illegal: Albion and Cross-Sheep are Forbidden
• Only 34.5% of main-deck copies are exact-name Thunder Dragon, so the engine is diluted
• 14 singletons and several single-copy Limited pieces (Druiswurm, Magnamhut, Lubellion, Fallen of Albaz) add brick and dependency risk
• No side deck, so there is no post-side plan
• Mixed Bystial, Albaz, Branded, Batteryman and Kuriboh pieces may conflict

Critical choke points

• Fallen of Albaz (1 copy) gates the Albaz fusion routes, including Lubellion and Mirrorjade
• The 3-copy Thunder Dragon core has a 0.34 chance of appearing in the opening five

Recommended changes

Evidence & confidence

• Verified: Main 40 and Extra 15 counts are within the OCG size rules; Albion the Branded Dragon and Cross-Sheep are Forbidden and each is run once; Remaining Limited cards are at legal copy counts (1 each) and Ash Blossom at 2 (Semi-Limited); Archetype purity is 34.5%; 14 singletons in the main deck
• Inferred: P(>=1 Thunder Dragon in 5) = 0.34 and P(>=1 searcher in 5) = 0.97; P(>=1 hand trap in 6, going second) = 0.76; Interaction density from hand-trap and negation text; Recovery and closing power read from card text
• Provisional: Meta Power is null: no dated metagame sample; Format fit (D13) is unknown without archetype meta-share
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot record are absent No win-rate telemetry in YGOVN for going-first/second, matchup or starter rates Meta Power is provisional without a dated metagame sample Deck title is null No side deck, so side-deck adaptability cannot be measured
