Thunder Dragon Deck #769074 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 50 / Extra 13 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Phantasm Sacred Beast boss summons (Calamity of the Sacred Beasts - Hamon, Infinity of the Sacred Beasts - Raviel, Chaotic Phantasmal Sacred Beasts) backed by Sacred Beast searchers and the Sacred Beasts Released / Thunderclap engine; Fiendsmith Lacrima / Desirae grind-and-equip, with Unchained and Mulcharmy as board-disruption and draw support
• Turn 1 (going first): T1: Summoner or Sacred Beasts Released to search a Sacred Beast; T2: Special Summon a Level 10 Sacred Beast boss from hand (Hamon / Raviel / Uria) and use Ash, Ghost Belle, or Infinite Impermanence to protect the line
• Turn 2 (going second): Hand traps (Ash, Ghost Belle, Infinite Impermanence, Nibiru, Great Gallant Bandit) to break the opponent's first summon, then rebuild with Sacred Beast searchers
• Recovery: Recursion via Martyr of the Sacred Beasts, Sacred Beasts Released GY effect, Ghost Belle GY recursion, and Fallen Paradise of the Sacred Beasts
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan. Any side-deck score here is structural only.

Why it scores here

The deck is a mixed pile of at least six archetype cores (Phantasm, Fiendsmith, Mulcharmy, Unchained, Fabled, Eyes Restrict) with only one exact-name Thunder Dragon card, so it does not form one engine. Its strongest reliable element is access: 22 searcher-text cards give about a 95% chance of at least one searcher in a 5-card opening hand (Inferred), and the Sacred Beast searchers feed level-10 boss summons. Interaction is dense, with 11 hand traps and 15 negation-text cards, so it can contest the first summon well on the going-second side. Its ceiling and median cannot be measured because the export has no recorded boards, and the Ash Blossom over-limit plus the absence of a side deck and any tournament or meta data cap the result. Popularity, archetype naming and the average of individual card scores did not earn points; the score comes from consistency, interaction and bosses on the system, and the legality failure caps it as a structural-only read.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Toolbox secondary, not separately weighted. Structural ≈ 53, Going First ≈ 42, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal copy-limit violation (-4); Engine conflicts (-4); No side deck (-3). Final formula: Illegal cap: min(0.80*Structural + 0.20*TournamentReliability + ContextModifiers, 25) = min(49.4 - 7, 25) = 25; theoretical / structural-only; Meta Provisional (null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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 hand-trap and negation package (11 hand traps, 15 negation-text cards)
• Strong searcher density (22 searcher-text cards) gives high opening-hand access
• Level 10 bosses at 4000-5000 ATK provide real closing pressure

Weaknesses

• Illegal as built: Ash Blossom runs 3 copies against a limit of 2
• Six or more archetype cores without a shared engine; exact-name purity is 1.6%
• No Side Deck, so no post-side plan
• No recorded boards, so combo ceiling and median are unmeasured

Critical choke points

• Level 10 Sacred Beast boss summon depends on a Sacred Beast effect; if the enabler is negated or never drawn, the boss line stops
• Limited cards (Fiendsmith Engraver, Lacrima, Tract, S:P Little Knight, Solemn Judgment, Linkuriboh) are singletons, so losing one removes its line

Recommended changes

Evidence & confidence

• Verified: Illegal: Ash Blossom & Joyous Spring runs 3 copies against a Semi-Limited limit of 2; Main 50 and Extra 13 are within OCG size limits; Side is 0 (legal but empty); Archetype exact-name purity is 1.6% (62 of 65 copies are off-archetype); Level 10 bosses: Calamity of the Sacred Beasts (4000/4000), Infinity of the Sacred Beasts - Raviel (4000/4000), The Chaotic Phantasmal Sacred Beasts (5000/5000)
• Inferred: Opening-hand access: P(>=1 searcher in 5) about 0.95; Hand-trap density: P(>=1 hand trap in 6 going second) about 0.79; Engine conflicts across Phantasm, Fiendsmith, Mulcharmy and Unchained cores
• Provisional: Format fit and meta share: no tournament or dated meta 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 win-rate telemetry (going-first/second, matchup, brick, starter or OTK rates) No Side Deck; post-side evaluation impossible Meta Power is Provisional unless a dated metagame sample is supplied
