Sangen Deck #460134 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Tempo
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Tenpai Dragon / Sangen FIRE Dragon engine into Sangenpai Transcendent Dragion and Trident Dragion boards (Inferred from card text; no recorded boards); Sky Striker and Tenpai Dragon Chundra Synchro/Link pressure with Tri-Brigade Arms Bucephalus II as a 3500 ATK closer (Inferred)
• Turn 1 (going first): Set up Tenpai Dragon Paidra or Sangen Summoning to search a FIRE Dragon, then use Sangen Kaimen or Dora Dora to bridge into a Synchro or Link; use Lightning Storm or Harpie's Feather Duster for backrow and board interaction (Inferred)
• Turn 2 (going second): Open a hand trap (Artifact Lancea, Droll & Lock Bird, Nibiru) against the opponent's first summon, then rebuild the Tenpai Dragon engine from the GY through Fadra and Genroku (Inferred)
• Recovery: Tenpai Dragon Fadra and Genroku revive FIRE Dragons from the GY; Sangen Summoning and Kaimen add the next engine piece (Inferred)
• After siding: No side deck is registered, so there is no post-side plan. Best-of-3 play is structurally unsupported in this list

Why it scores here

The deck's engine is accessible but not reliably so: the Tenpai Dragon Paidra copies give about a 25% chance of one in a 5-card opening hand, and the 10-copy archetype-core group gives about 65% at least one in hand (Inferred). The 14 Extra Deck cards (7 Synchro, 6 Link) give real follow-up once the engine is live. Interaction is broad, with 8 hand traps and several board-wipe and backrow-destruction spells, which earns credit for going second. The list runs 17 single-copy cards and many tech cards, so brick rates are high and the opening hand is often narrow. Popularity and archetype usage data confirm the list is recognizable but did not earn points. Card scores were not averaged. The score is capped low because the list is illegal: it runs Forbidden cards and exceeds copy limits on several Limited and Semi-Limited cards. No recorded boards exist, so the combo floor and median are text-only inference.

Dimension scores

How the score was computed

Strategy profile: 0.8 Midrange / 0.2 Toolbox. Structural ≈ 51, Going First ≈ 48, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-6); no side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (-8) = 39.8, then capped to 25 because the list is Illegal (theoretical/structural-only). Meta Power provisional/null.

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

• Deep Extra Deck with 7 Synchro and 6 Link options
• Broad interaction suite: hand traps, board wipes and backrow destruction
• Searchers and FIRE Dragon recursion support multi-turn resilience

Weaknesses

• Illegal list: Forbidden cards and copy-limit violations
• No side deck
• High brick risk from 17 single-copy cards and 18 tech cards
• Thin Sangen core (exact-name purity 7.1%)

Critical choke points

• Tenpai Dragon Paidra and Sangen Summoning as the main engine starters; roughly a 25% chance each in an opening hand
• Single-copy Synchro and Link Extra Deck monsters limit the second line

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0; main within 40-60 and extra within 0-15; Five copy-limit violations and three Forbidden cards (legality block); Card text and stats for all listed cards (cards block)
• Inferred: Engine starter probabilities and archetype-core group probability (hypergeometric); Hand-trap probability on going second; Going-first and going-second plans from card text; Dimension scores D1-D11 and D14
• Provisional: D12 side deck adaptability (no side deck); D13 matchup and format fit (no dated meta sample); Meta Power (null)
• Data gaps: No parseable combos; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and pilot record absent No win-rate telemetry; going-first and going-second splits are Inferred No side deck registered Meta Power is provisional without a dated metagame sample
