Sangen Deck #774641 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 41/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun, Mechanic: Synchro, Mechanic: Link
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro Summon Tenpai Dragon / Angelechy / Sangen boards with Sangenpai Transcendent Dragion (3000 ATK) and Kewl Tune B2B (3200 ATK) as the closers in the Extra Deck; Angelechy Shatranga and Angelechy Destrier banish or control-swap from the Extra Deck to clear blockers
• Turn 1 (going first): Opening Tenpai Dragon Paidra / Mulcharmy / Sangen Summoning to add a Tenpai Dragon and Synchro into Angelechy or Sangenpai; Heat Wave and Nibiru are the disruption backups
• Turn 2 (going second): Hold Ash Blossom, Effect Veiler, Droll & Lock Bird and Ghost Ogre to answer the opponent's first Special Summon or activation, then rebuild a Tenpai/Angelechy board
• Recovery: Sangen Kaimen and Tenpai Dragon Genroku to rebuild a FIRE Dragon board from the GY; Angelechy Problem to re-place a Level 2 Angelechy from the Extra Deck
• After siding: Not applicable: the deck has no Side Deck (side_count 0), so there is no post-side plan

Why it scores here

The deck is scored as a system, not as an average of its cards. Its consistency rests on a Tenpai Dragon / Sangen searcher package (Sangen Summoning, Sangen Kaimen, Tenpai Dragon Paidra and Genroku) that has roughly a 65% chance of at least one searcher in the opening 5, which is a reasonable but not dependable engine start (Inferred). Interaction is its strongest axis: 16 hand traps and 15 negation-text cards give an 89% chance of at least one hand trap in a going-second 6-card hand (Inferred), which keeps the deck relevant against an established board. The closing power is real but thin: the Extra Deck carries Sangenpai Transcendent Dragion and Kewl Tune B2B as boss threats, while several recorded closers (Trident Dragion, Assault Blackwing Kusanagi) are absent from this list. Popularity did not earn points: the Sangen archetype stats show a high core-card inclusion rate, but that confirms the list is a real build rather than making it strong. The legality violation (Ash Blossom and Dominus Impulse at 3 copies against a Semi-Limited limit of 2) caps the score and makes this evaluation theoretical/structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Illegal copy-limit violation (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers; Illegal copy-limit violation applied as a modifier

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.65 · 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

• Layered hand-trap and negation package (16 hand traps, 15 negation-text cards) covering the first Special Summon or activation
• Synchro Extra Deck with several 3000+ ATK closers (Sangenpai Transcendent Dragion, Kewl Tune B2B, Angelechy Bastion)
• Searcher and recovery text (Sangen Summoning, Sangen Kaimen, Genroku, Angelechy Problem) gives some redundancy in the Main Deck

Weaknesses

• Illegal as built: two cards run over their Semi-Limited copy limit
• No Side Deck, so no post-side adaptation
• Low archetype purity (5.7% exact name); a mix of Angelechy, Tenpai, Mulcharmy and generic hand traps lowers engine coherence
• No recorded combos or tournament data, so the floor and ceiling cannot be measured

Critical choke points

• Tenpai Dragon Chundra and Sangenpai Transcendent Dragion are Synchro-dependent; a single Tuner loss stops the Sangen closing line
• Searcher-text group reaches only ≈65% in the opening 5, so a missing Sangen searcher can leave a hand with no engine

Recommended changes

Evidence & confidence

• Verified: Legality: 55 Main / 15 Extra / 0 Side; Ash Blossom and Dominus Impulse over Semi-Limited limit (Illegal); Limited cards run at 1 copy each (Bystial Magnamhut, Droll & Lock Bird, Harpie's Feather Duster, Sangen Kaimen, Sangen Summoning, Tenpai Dragon Chundra, Terraforming); Extra Deck is 15/15 with 14 Synchro and 1 Link
• Inferred: Searcher-text group P(≥1 in opening 5) ≈ 0.65; Hand-trap group P(≥1 in going-second 6) ≈ 0.89; Interaction quality (D7) as the deck's strongest axis
• Provisional: Meta Power is null: no dated metagame sample; D13 matchup fit: no tournament data
• 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 no win-rate telemetry: going-first/second, matchup and brick rates are Inferred or unknown Meta Power is Provisional unless a dated metagame sample is supplied no guides attached for the archetype
