Tenpai Dragon Deck #667239 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Tenpai Dragon and Sangen board presence feeding Synchro and Link finishers from the Extra Deck (Sangenpai Bident Dragion x2, Sangenpai Transcendent Dragion, Trident Dragion, Sky Striker Ace - Zero, Tri-Brigade Arms Bucephalus II); Sky Striker Ace - Kagari and Sky Striker Ace = Zero pressure after Sky Striker Mecha - Hornet Drones token setup
• Turn 1 (going first): Open Tenpai Dragon Paidra or Genroku plus a Sangen searcher (Sangen Summoning or Sangen Kaimen), search a Tenpai Dragon, then Synchro or Link into a board-breaking monster
• Turn 2 (going second): Use hand traps (Maxx C, Red Reboot) and end-board spells (Raigeki, Dark Hole, Heavy Storm, Harpie's Feather Duster, Lightning Storm) to clear the opponent's board, then extend through the Tenpai Dragon engine
• Recovery: Recover with Sangen Summoning and Sangen Kaimen searches, Upstart Goblin and Into the Void draws, and Tenpai Dragon Genroku recursion; the 6 exact-name Tenpai Dragon copies are the thin point
• After siding: Not evaluable: the deck has 0 side cards, so no post-side plan exists

Why it scores here

The deck is scored as a system, not as an average of its cards. It opens a functional plan reasonably often: the 16 archetype-family copies give a 0.94 proxy chance of at least one in a 5-card opening hand, but only 6 copies are exact Tenpai Dragon names (10.9% exact purity), so the engine itself is thin. Its real strength is end-board interaction: Raigeki, Dark Hole, Heavy Storm, Harpie's Feather Duster, Lightning Storm, Forbidden Droplet, Red Reboot and Maxx C give it strong going-second board breaking and layered answers. Closing power comes from a 15-card Extra Deck with several 2600 to 3500 ATK finishers. Popularity and archetype usage were not used as points, and the deck is capped because it is Illegal: Called by the Grave is Forbidden in Master Duel and must be removed before any normal score applies. This evaluation is theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 52, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-5); dependence on exact-name Tenpai core (-4). Final formula: No-meta formula: 0.80*52 + 0.20*42 + modifiers (-9) = 41; Illegal cap applied, so final score = 30 (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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 end-board interaction: Raigeki, Dark Hole, Heavy Storm, Harpie's Feather Duster, Lightning Storm, Forbidden Droplet, Red Reboot, Maxx C
• Strong Extra Deck finishers with 3000 to 3500 ATK
• Sangen and Sky Striker searchers add some route redundancy

Weaknesses

• Illegal list: Called by the Grave is Forbidden in Master Duel
• Only 6 exact-name Tenpai Dragon copies (10.9% purity), so the engine is thin
• 32 Spells in a 40-card Main Deck, with no side deck
• No recorded combos, so the power of the engine cannot be verified

Critical choke points

• Paidra and Fadra are the main Tenpai engine pieces, and each is only 1 to 2 copies
• Sangen Summoning and Sangen Kaimen are Limited (1 copy each), so search redundancy is capped

Recommended changes

Evidence & confidence

• Verified: Main Deck size 40 is legal (range 40 to 60); Extra Deck 15 is legal (max 15); Called by the Grave is Forbidden with 0 legal copies, run at 1 copy; Red Reboot is Semi-Limited (2 legal copies), run at 1 copy; the Limited cards are legal at 1 copy each; Card text for all 40 Main and 15 Extra cards
• Observed: Usage statistics show 52.4% of archetype core cards present (11 of 21)
• Inferred: Hypergeometric starter and brick estimates; Going-second interaction density from card text; Median and ceiling estimates from text only
• Provisional: Meta Power and matchup fit (D13), no 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 records are absent No win-rate telemetry exists in YGOVN for going-first, going-second, matchup, brick or OTK rates No side deck (0 cards), so post-side performance cannot be evaluated Meta Power is Provisional without a dated metagame sample The deck is Illegal (Forbidden Called by the Grave), so only a structural score applies
