Bamboo Sword Deck #774686 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 36/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Fusion, Xyz, Link, Pendulum
• Format: master-duel

Legality

Main 41 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Extra Deck pressure from Endymion (2800 ATK), Dark Magician of Destruction (2800 ATK), and Aiwass / Possessed Destiny - Wynn, usually after a Spell-counter or Fusion Gate line puts them on the field.; Equip-based damage: Cursed / Golden / Original Bamboo Sword plus Wonder Wand on a live monster, with Original Bamboo Sword able to destroy the opponent's monsters after a direct attack.
• Turn 1 (going first): Open on Summoner Monk or Royal Magical Library, draw or search with Upstart Goblin, Wonder Wand, or Golden Bamboo Sword, then bridge into Endymion or Verre through the Spell-counter engine (Magical Citadel of Endymion, Spell Power Mastery).
• Turn 2 (going second): Rely on one of the two Negation-text cards (Endymion, Spell Power Attainment) and conditional removal (Magia Magic - Thunder of Judgment, Summer Schoolwork Successful!) to break the first board, then convert with a Fusion or Xyz summon. No hand traps are present.
• Recovery: Recursion is thin: Pot of Benevolence, Spellbook of Knowledge, and Royal Magical Library's Spell-counter draw. Rebuild relies on Upstart Goblin and Wonder Wand draw effects.
• After siding: No Side Deck is registered, so there is no post-side adaptation in this list.

Why it scores here

The deck reliably opens on a 3-copy starter at only about 33% per opening hand (Summoner Monk or Royal Magical Library), so its engine is live on turn 1 in roughly one game in three, and only 9 of 41 Main Deck cards are monsters. Structurally it runs four partly overlapping engines (Bamboo Sword equips, Magistus, Endymion Spell counters, and a Fusion Gate / Dark Magician of Destruction line), which dilutes consistency and lowers the score. Its ceiling comes from Extra Deck closers and Original Bamboo Sword's board-breaking effect, and its draw density (Upstart Goblin, Royal Magical Library, Wonder Wand, Spellbook of Knowledge) keeps it moving. Interaction is thin: no hand traps and only two Negation-text cards, so going-second power is weak and the deck is strained against an established board. The score comes from consistency, median output, and interaction measured on the whole system, not from averaging card scores, and the deck's Bamboo Sword archetype label does not earn points on its own.

Dimension scores

How the score was computed

Strategy profile: 70% Combo / 30% Toolbox. Structural ≈ 43.5, Going First ≈ 42, Going Second ≈ 33, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: engine conflicts (-4); no side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Structural 43.5, TR 35, modifiers -6 => 35.8, rounded to 36)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.33 · key two-card combo ≈ — · full-brick estimate ≈ 0.27 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Three-copy draw and search engine (Upstart Goblin, Royal Magical Library, Golden Bamboo Sword, Into the Void) keeps hands moving
• Extra Deck closers at 2800 ATK (Endymion, Dark Magician of Destruction) plus Aiwass as an equip threat
• Original Bamboo Sword gives a board-breaking route after a direct attack
• Legal construction with no copy-limit issues

Weaknesses

• Only 9 monsters in 41 Main Deck cards, so many hands cannot start the engine
• Four overlapping engines reduce consistency and slow down the turn-1 plan
• No hand traps and only two Negation-text cards, so going-second interaction is weak
• No Side Deck registered, so there is no post-side plan
• Into the Void (x3) discards the entire hand if you have 3 or more cards in hand, a self-harm card in a low-monster deck

Critical choke points

• Summoner Monk and Royal Magical Library are the only 3-copy monster starters, so drawing neither leaves most hands without an engine
• Endymion is a single copy and carries both the Spell-counter removal engine and Negation text
• Fusion Gate and Chain Material are single copies on the Dark Magician / Fusion route

• Inferred: Going-first starter probability (P >= 1 3-copy starter in 5 = 0.33); Brick estimate (P no monster in 5 = 0.27); Engine conflicts and interaction thinness read from card text; Combo ceiling and median from card text alone (no combos supplied)
• Provisional: Matchup and format fit (D13), because no tournament data or dated meta sample was supplied; Meta Power (null)
• 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 no win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck registered; post-side performance unknown
