Thunder Dragon Deck #768466 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Combo, Toolbox
• 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: Boss monsters from the Extra Deck (Thunder Dragon Titan 3200, Thunder Dragon Colossus 2600, Chaos Angel 3500, Bystial Dis Pater 3500, Archnemeses Eschatos 3000, Chaos Emperor 3000) reached through Thunder Dragon searchers and Fusion/Synchro/Link summons.; Going-second board breaking through Archnemeses Eschatos (type-based mass destroy) and Chaos Dragon Levianeer.
• Turn 1 (going first): Normal Summon a searcher (Thunder Dragon, Thunder Dragondark, Thunder Dragonroar, or Black Dragon Collapserpent), search a second Thunder Dragon piece, then Fusion or Link through Thunder Dragon Fusion or Ready Fusion. Starter access is thin: P(Thunder Dragon itself in opening 5) is about 0.34.
• Turn 2 (going second): Six-card hand with a searcher; use Infinite Impermanence, Bystial Druiswurm or Magnamhut as interaction and rebuild through GY and banish recursion (Dragonroar, Dragonhawk, Wyverburster, Collapserpent).
• Recovery: Recursion from GY and banish zones: Thunder Dragonroar and Thunder Dragonhawk add or summon Thunder Dragon cards from GY or banish; Branded Regained and Chaos Space refill the hand.
• After siding: No Side Deck is registered (side_count 0), so no post-side plan exists in the evidence. Unknown, not assessed.

Why it scores here

The deck reliably opens into a searcher: the searcher-text group (21 cards) has P(at least one in an opening 5) of about 0.98, so the engine is accessible even though any single Thunder Dragon starter is only about 0.34 to appear in the opening hand (Inferred). Its closing power is genuinely high, because the Extra Deck holds several 2600 to 3500 ATK bosses and Fusion, Synchro and Link access. Consistency is held back by a split identity: only 13 of 40 main-deck copies carry the exact Thunder Dragon name (23.6% exact-name purity), and the rest run Chaos, Bystial, Batteryman, Charmer and generic cards with no shared engine. There are no recorded boards, no tournament link, and no guides, so the floor, median and ceiling of combo output are unmeasured and the score rests on structure alone. The deck is Illegal as submitted (Allure of Darkness and The Bystial Lubellion each run 2 copies against a limit of 1), and it has no Side Deck. The score is therefore a capped, theoretical structural read, and the score was not averaged from card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Combo secondary (about 80/20 for weighting). Structural ≈ 52, Going First ≈ 50, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); no_side_deck (-4); illegal_cap (0). Final formula: Illegal cap: 0.80*Structural(52) + 0.20*TournamentReliability(45) = 50.8, then modifiers (−12) = 38.8, capped to 35 as a theoretical, structural-only score because the deck is Illegal. Meta Power provisional/null.

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

• Searcher density is very high, so the engine is almost always accessible past the opening hand
• Extra Deck contains several high-ATK bosses and offers Fusion, Synchro and Link access
• Recursion routes from GY and banish give some resource regeneration

Weaknesses

• Illegal as submitted: two cards exceed their Limited copy limit
• Low exact-name purity (23.6%) splits the engine across Chaos, Bystial, Batteryman and Charmer
• No Side Deck registered, so no post-side adaptability
• Several GY-banish-dependent summon conditions that can brick

Critical choke points

• Thunder Dragon itself appears in only about 34% of opening hands, so the searcher chain has to carry the early game
• Single-copy Limited cards (Gold Sarcophagus, Chaos Space, Foolish Burial, Striker Dragon, Magnamhut, Druiswurm) are key interaction and engine pieces with no redundancy

Recommended changes

Evidence & confidence

• Verified: Main 40 and Extra 15 counts are legal for OCG size rules; Allure of Darkness and The Bystial Lubellion run 2 copies against a Limited limit of 1 (Illegal); Exact-name Thunder Dragon purity is 13 of 55 copies (23.6%); Boss ATK values for Titan 3200, Chaos Angel 3500, Dis Pater 3500, Eschatos 3000, Chaos Emperor 3000, Levianeer 3000
• Inferred: Searcher-group P(≥1 in opening 5) ≈ 0.98 and Thunder Dragon P ≈ 0.34 (hypergeometric); GY-banish-dependent summons create brick risk; Engine coherence is reduced by the multi-archetype spread; Interaction and board-breaking quality from card text
• Provisional: Meta Power and matchup fit (no dated meta sample, no tournament link); Side-deck adaptability (no side deck registered)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record absent usage_statistics rows (Aleister, Magical Meltdown, Invoked cards) do not match this deck's Thunder Dragon core, so they cannot be used to judge the core and were not used No Side Deck registered (side_count 0) No guides for the Thunder Dragon archetype No win-rate telemetry exists in YGOVN; Meta Power is provisional
