Thunder Dragon Deck #758509 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 21/100 (±8 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Control
• 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: Not established: no recorded boards and no Fusion enabler in the Main Deck that can reliably feed the 15 Extra Deck Fusion Monsters; the Thunder Dragon engine is only 3 copies.; Generic toolbox pressure: Black Luster Soldier - Envoy of the Beginning (3000 ATK) and Gatling Dragon, both needing Special Summon or Fusion conditions that are not reliably supplied.
• Turn 1 (going first): Open a Thunder Dragon searcher (P at least one in 5-card hand about 0.25) or a draw spell, and hope for a bridge into a Fusion or Special Summon line; no reliable T1 plan is visible in the evidence.
• Turn 2 (going second): Use Torrential Tribute, Ring of Destruction, Heavy Storm, Mirror Force and Solemn Judgment as reactive interaction, then rebuild through searchers (Sangan, Sinister Serpent, Magician of Faith, Thunder Dragon).
• Recovery: Searchers and draw spells (Upstart Goblin, Jar of Greed, Card Destruction, Dekoichi) are the recovery route; Card Destruction is a single copy.
• After siding: Not available: the deck runs 0 Side Deck cards, so no post-side plan can be evaluated.

Why it scores here

This is an illegal list: three Forbidden OCG cards (Delinquent Duo, Pot of Greed, Graceful Charity) and three copies of the Limited Solemn Judgment are run, so it receives a structural-only score capped low and is not a normal Final Contextual score. The deck reliably reaches interaction (Torrential Tribute, Ring of Destruction, Heavy Storm, Mirror Force, Solemn Judgment) and a few searchers, but its engine is thin: only 3 Thunder Dragon, 0 Thunder Dragon Colossus, and a Thunder Dragon searcher that is live in an opening 5-card hand only about 25 percent of the time. The 15 Fusion Monsters need named materials that are not in the Main Deck, and Metamorphosis (2 copies) is the only Fusion-enabling card, so most of the Extra Deck is structurally dead. The archetype popularity and the 36 distinct Main Deck cards did not earn points, and no card scores were averaged into the deck score; the score comes from the system's consistency, low conversion and missing side plan.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 34, Going First ≈ 30, Going Second ≈ 36, Meta = provisional, Tournament Reliability ≈ 25. Modifiers: banlist exposure (-8); unrecoverable Extra Deck dependence (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Illegal list, so result is theoretical/structural-only and capped low before modifiers

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 interaction suite: Torrential Tribute, Ring of Destruction, Heavy Storm, Mirror Force, Solemn Judgment, Torrential Tribute
• Several searchers and draw spells give some resource recovery
• Compact Main Deck size (55 cards) within the OCG range of 40-60

Weaknesses

• Illegal list: three Forbidden cards and one Limited card over its copy limit
• Thunder Dragon engine is only 3 copies with no Colossus
• Most Fusion Monsters have no reachable Fusion path in the Main Deck
• No side deck

Critical choke points

• A single Fusion enabler (Metamorphosis) gates most of the Extra Deck
• The Thunder Dragon searcher is the only archetype-linked starter and is live about 25 percent of the time in going-first hands

Recommended changes

Evidence & confidence

• Verified: Legality: 55 Main / 15 Extra / 0 Side; Forbidden cards Delinquent Duo, Pot of Greed, Graceful Charity run; Solemn Judgment 3 copies vs Limited 1; Archetype purity 4.3 percent; Thunder Dragon 3 copies; no Thunder Dragon Colossus in the deck; Card text for Metamorphosis, Torrential Tribute, Ring of Destruction, Heavy Storm and Mirror Force
• Inferred: Opening-hand starter probability 0.25 for Thunder Dragon; Fusion Monsters are largely unreachable without named materials; Interaction density yields a good going-second board-breaking profile; Reliability is low due to one searcher and one enabler
• Provisional: Meta Power and matchup fit (no dated metagame sample)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match record absent No win-rate telemetry for going-first, going-second, matchup or brick rate Meta Power is Provisional No Side Deck: post-side plan cannot be evaluated
