Deck — Deck Power Evaluation

Final Contextual Deck Power: 49/100 (±8 · Confidence: Medium)

• Primary strategy: Toolbox
• Secondary strategies: Stun, Midrange
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro beatdown: Trident Dragion, Baronne de Fleur, Samurai Destroyer and Super Starslayer TY-PHON are the Extra Deck closers once a Tenpai or Sangen board is established.; Hand-refill grind: Mulcharmy Fuwalos and Purulia draw on opponent summons, Pot of Sloth draws, and Dora Dora excavates, so the deck can outlast a board without a single starter.
• Turn 1 (going first): Open on Tenpai Dragon Genroku (Tuner when added to hand, Tribute to Special Summon a Tenpai Dragon) or Tenpai Dragon Paidra (search a Sangen Spell/Trap), protect with Sangen Summoning, then extend into a 3000-ATK synchro. Fire Dark Hole or Raigeki if the opponent builds a board first.
• Turn 2 (going second): Hold the mass-removal spells (Dark Hole, Raigeki, Heavy Storm, Lightning Storm, Harpie's Feather Duster) and Maxx "C" as the lone hand trap; use Mulcharmy draws on opponent summons to find the answer, then start a Tenpai or Sangen extension on the next turn.
• Recovery: Revive Tenpai Dragon Fadra or Sangenpai Bident Dragion from the Graveyard (both can Special Summon a Level 4 or lower FIRE Dragon from the GY), refill the hand with Mulcharmy and Pot of Sloth, and re-search with Dora Dora or Sangen Kaimen.
• After siding: None. The deck runs 0 side cards and Master Duel gives no sideboard swap, so the plan is the same in every game.

Why it scores here

The deck reliably opens into interaction: eight spell or trap answers (Dark Hole, Raigeki, Heavy Storm, Lightning Storm, Harpie's Feather Duster, Forbidden Droplet, Book of Eclipse, Illusion Gate) plus Maxx "C" let it control the field and then extend. Its engine is thin, with only 7 exact Tenpai Dragon copies (12.7% exact-name purity) and a single Genroku/Paidra starter that appears in an opening 5 about one time in three (Inferred), so the consistency score sits in the low 50s. Conversion and median output are scored from card text alone because no recorded boards exist; the Synchro endboard (3000-ATK Trident and Baronne, 2600 Samurai Destroyer) and Graveyard revivals give a plausible ceiling that is not confirmed by data. Mulcharmy's draw effects and Pot of Sloth earn credit for grind and recovery, but the "if you control no cards" and "no face-up cards" conditions conflict with the Tenpai board, which is why the pilotability and resilience scores are moderate. Popularity and usage statistics confirm the list is a real, accessible build but earn no power points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 54.7, Going First ≈ 60, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Engine conflicts (-3); Engine compactness (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 53.8 before modifiers

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

• Eight spell or trap answers and one hand trap give broad interaction on both turns.
• Extra Deck synchro closers at 2500-3000 ATK, with Trident Dragion running 2 copies.
• Mulcharmy and Pot of Sloth give hand refill and grind into a long game.
• Graveyard revivals (Fadra, Bident) provide recovery after a removal exchange.

Weaknesses

• No combo data at all, so consistency and conversion are read from text only.
• Low exact-name archetype purity (12.7%) and a diffuse 21-card main deck.
• Only one hand trap (Maxx "C"), so going-second interaction depends on drawing spells.
• Mulcharmy's empty-field requirement conflicts with the Tenpai board and with Lightning Storm.
• No side deck, so no post-side adaptation.

Critical choke points

• Genroku (3) and Paidra (2) are the only Tenpai starters that open the engine; a hand with neither has no Tenpai line.
• Sangen Summoning and Sangen Kaimen are one copy each and are the only protection for the FIRE Dragon board.
• Tenpai Dragon Chundra is a single Limited copy that is needed for the Synchro line.

Recommended changes

Evidence & confidence

• Verified: Legality: 40 Main / 15 Extra / 0 Side within Master Duel size rules; all 6 Limited cards run at 1 copy (legal_copies 1).; Copy histogram and extra-deck breakdown reconcile to 40 and 15 cards.; Card text excerpts for Genroku, Paidra, Fadra, Chundra, Sangen Summoning, Sangen Kaimen, Mulcharmy, Dark Hole, Raigeki and the synchros.; Archetype purity 12.7% (7 of 55 copies in the exact archetype name).
• Inferred: Hypergeometric starter odds (0.34 per 3-copy card in an opening 5).; Brick and dead-hand risk from spell-heavy composition.; Toolbox/Stun classification from interaction density and the absence of combo evidence.; Going-first and going-second estimates and recovery routes from card text.
• Provisional: Meta Power (null) and matchup fit (D13) need a dated metagame sample.
• 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. usage_statistics flags Trident Dragion, Sangenpai Bident Dragion, Kuibelt the Blade Dragon, Golden Cloud Beast - Malong and Sangenpai Transcendent Dragion as in_this_deck=false, but the cards list runs them (copies 2, 2, 1, 1, 1). core_present_pct 52.2 and missing_core are therefore unreliable. The deck title is null; the deck is identified only by its archetype. The only guide (Vietnamese, topic 967) has no parsed sections; the snippet only supports a 'thin core, many staple hand traps' reading. No win-rate telemetry exists in YGOVN (going-first/second, matchup, brick/starter rates); those signals are Inferred or Unknown. Meta Power is Provisional unless a dated metagame sample is supplied.
