Thunder Dragon Deck #769358 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 54 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Special Summon and attack with Thunder Dragon boss monsters (Thunder Dragon Titan 3200, Thunder Dragonduo 2800, Thunder Dragonlord 3000) after a searcher-driven Thunder Dragon engine; Link and Fusion boss monsters (Thunder Dragon Thunderstormech, Black Luster Soldier, Thunder Dragon Colossus) reached through Fusion Summons and GY/banish-cost revivals
• Turn 1 (going first): Use Thunder Dragon searchers (Thunder Dragonmatrix, Thunder Dragon, Thunder Dragondark, Thunder Dragonroar) to fetch engine pieces, then convert into a fusion or Special Summon boss; floodgates and Lightning Storm protect the board
• Turn 2 (going second): Open with the six-card hand; use Ash Blossom, Nibiru and other hand traps to break the opponent's starter, then rebuild through searchers into a boss
• Recovery: Banish and GY-cost effects (Thunder Dragonroar, Thunder Dragonhawk, Thunder Dragonduo) re-deploy Thunder Dragons from the GY and banish zone
• After siding: Not assessable: the deck has 0 Side Deck cards, so no post-side plan exists

Why it scores here

This list is Illegal under the OCG banlist: three copy-limit violations (Allure of Darkness x3 against a limit of 1, Ash Blossom & Joyous Spring x3 against 2, Super Polymerization x3 against 2). It also has no Side Deck, so the best-of-3 adaptation dimension is near zero. Under the Midrange profile the system scores about 56 structurally: a dense searcher-text package (19 searcher cards; P(at least one in a 5-card opening hand) about 0.90) and several hand traps give it a plausible engine and a good going-second read, and its boss monsters (2800 to 3200 ATK) give it real closing power. The score is not derived from Thunder Dragon being a popular archetype or from averaging card scores; no combos, guides, or tournament data are supplied, so combo floor and ceiling and matchup fit are text-based inferences. Because the deck is illegal, it does not receive a normal Final Contextual score; the value shown is a capped, theoretical, structural-only read.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 56, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist and copy-limit violations (-6); No Side Deck (-4); Illegal-deck cap (-14). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*56 + 0.20*45 = 54 before modifiers; modifiers -10 gives 44; Illegal-deck cap applied gives 30 (theoretical, structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · 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 package (19 searcher-text cards) gives high P(>=1 starter) of 0.897 in the opening hand
• Six hand traps (Ash Blossom, Nibiru and others) give real going-second interaction
• Boss monsters at 2800 to 3200 ATK give strong closing pressure
• Recursion routes (Thunderdragonroar, Thunderdragonhawk) recover from disruption

Weaknesses

• Illegal as built: three copy-limit violations under the OCG banlist
• No Side Deck, so no adaptation for best-of-3
• Low exact-name purity (38%) and a wide off-archetype spread (Batteryman, Cyclone, Mulcharmy, Chaos, Eyes Restrict, Harpie, Black Luster Soldier)
• Many GY and banish-cost summons raise pilot demand and brick risk

Critical choke points

• Boss Special Summon conditions depend on specific Thunder monsters in the GY or banished zone
• Limited and Semi-Limited staples (Foolish Burial, Gold Sarcophagus, Instant Fusion, Harpie's Feather Duster, Chaos Space) are each run at the limit, so one lost draw removes a key line

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal under OCG rules with three copy-limit violations; Composition: 54 Main, 14 Extra, 0 Side; 10 Fusion and 4 Link in the Extra Deck; Archetype purity: 38.2% exact-name Thunder Dragon; Card text and stats for all listed cards (Thunder Dragon Titan 3200 ATK, Thunder Dragonduo 2800 ATK, Thunder Dragonlord 3000 ATK)
• Inferred: Starter access: P(>=1 searcher-text card in 5-card opening hand) = 0.897; Going-second hand-trap access: P(>=1 in 6 cards) = 0.525; Engine consistency and brick estimates from composition and card text; Interaction quality read from removal and hand-trap text
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link; Tournament reliability: inferred from consistency signals only
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No guides attached for the archetype No tournament link: archetype meta share and per-pilot match record are absent No win-rate telemetry exists in YGOVN (going-first/second, matchup, brick and starter rates) Deck has no Side Deck, so post-side performance cannot be assessed Core usage stats: none of the 7 archetype core cards are present in this list Meta Power is Provisional unless a dated metagame sample is supplied
