Tenpai Dragon Deck #772354 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Stun
• 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: Synchro Summon 3000-ATK boss monsters (Sangenpai Transcendent Dragion, Angelechy Shatranga, Angelechy Bastion, Assault Blackwing - Kusanagi) from a 14-Synchro Extra Deck and convert field presence into attacks; Angelechy Field Spell column pressure and banish-based removal from Synchro monsters
• Turn 1 (going first): Open with a Tenpai Dragon Paidra or Terraforming search, Normal Summon into a Synchro chain (Genroku or Chundra as Tuner), and use Angelechy Opening to e4 when the opponent goes first
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Ghost Ogre and Infinite Impermanence for the opponent's first Special Summon or activation, then rebuild through Mulcharmy draws and the Sangen/Tenpai searchers
• Recovery: Recover by Special Summoning Tenpai Dragon monsters from the GY (Fadra, Genroku) and drawing through Mulcharmy Fuwalos and Purulia when the board is empty
• After siding: No Side Deck is registered, so no post-side plan can be evaluated; the deck cannot legally side cards in a best-of-3 as built

Why it scores here

The deck reliably opens a functional starter in most hands: the archetype core has a 0.96 chance of at least one copy in a 5-card opening hand, and the searcher text group (Paidra, Sangen Summoning, Terraforming, Kaimen) has a 0.78 chance of at least one hit, so engine access is good (Inferred). Its interaction package is large, with 10 hand traps and 10 negation-text cards, which gives it a real going-second plan, since the hand-trap group has an 0.85 chance of at least one card in a 6-card hand. Conversion is the weak point: there are no parseable recorded boards, no combo evidence, and no median output data, so floor and ceiling are text-only estimates. The deck's exact-name purity is only 12.7%, because it splits its engine across Tenpai Dragon, Angelechy, Mulcharmy, Sangen, Dominus and Bystial, which raises the risk of conflicting routes. The score is capped because two cards exceed their copy limits (Ash Blossom and Dominus Impulse each run 3 copies against a limit of 2), and the score was not derived by averaging card scores. Popularity and archetype usage did not earn points; the usage data only confirms the core cards are real and accessible.

Dimension scores

How the score was computed

Strategy profile: Midrange weights applied; Stun secondary noted but not blended because the deck is Illegal and capped. Structural ≈ 52, Going First ≈ 46, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist and copy-limit exposure (-8); engine conflicts across sub-archetypes (-4). Final formula: Structural 52 (Midrange profile); unmodified 0.80*52 + 0.20*40 - 12 = 38; Illegal deck capped to 30 (theoretical / structural-only). 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

• Engine access: archetype core P(>=1 in hand5) ≈ 0.96 and searcher group ≈ 0.78 (Inferred)
• Interaction density: 10 hand traps and 10 negation-text cards give going-second resilience (Inferred)
• Four 3000-ATK Synchro bosses provide closing power (Inferred)

Weaknesses

• Illegal as built: two cards exceed copy limits
• No Side Deck, so no post-side plan and no best-of-3 adaptability
• Low exact-name purity (12.7%) and split engines across six sub-archetypes
• No combo or median-output evidence to confirm conversion

Critical choke points

• Synchro summon access: the Extra Deck boss monsters need Tuners and non-Tuners, so a Tuner shortage stops conversion
• Angelechy Field Spell and column placement for the Angelechy engine
• Searcher access to Tenpai Dragon Paidra (3 copies) for the Sangen and Tenpai engine

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0 counts, copy histogram 9/5/7, and archetype spread from the evidence pack; Ash Blossom and Dominus Impulse each run 3 copies against a Semi-Limited limit of 2; Limited cards (Bystial Magnamhut, Droll & Lock Bird, Sangen Kaimen, Sangen Summoning, Tenpai Dragon Chundra, Terraforming) each run 1 copy, which is legal
• Inferred: Opening-hand engine access from the hypergeometric estimates (0.96 core, 0.78 searcher, 0.85 hand-trap group); Interaction quality and going-second plan from card text; Closing power from Synchro boss ATK values
• Provisional: Meta Power (null, no dated metagame sample); Format fit (no tournament link or archetype meta-share)
• 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 are absent No win-rate telemetry: going-first and going-second splits are Inferred only Meta Power is Provisional without a dated metagame sample Side Deck is empty, so post-side performance cannot be assessed
