Voiceless Voice Deck #770308 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Ritual-summon Lo and Saffira / Skull Guardian (up to 4100 ATK with Lo on field) and close with Ame no Murakumo, Sauravis or an Extra Deck boss (Chaos Angel, Super Starslayer, Galaxy-Eyes Photon Lord).; Extra Deck link and synchro boards (Dyna Mondo, ASHLAN U1000, Chaos Angel) built from recovered Ritual monsters.
• Turn 1 (going first): Search with Pre-Preparation of Rites or Nadir Servant, then Normal Summon Lo or Diviner to open a Ritual Summon line (Prayers of the Voiceless Voice / Mitsurugi Ritual) toward Skull Guardian or Murakumo.
• Turn 2 (going second): Hold Droll & Lock Bird and Maxx "C" to answer the opponent's first Special Summon or card add, then rebuild through Blessing / Radiance / Mitsurugi searchers.
• Recovery: Recycle banished or GY Voiceless Voice cards with Blessing of the Voiceless Voice and Radiance, and re-Ritual from the GY via Saffira and Mitsurugi Mirror.
• After siding: Not applicable: Master Duel has no side deck (side count 0), so there is no post-side plan.

Why it scores here

The deck reliably opens a functional starter: the archetype core group has about a 99.5% chance of at least one copy in a 5-card opening hand, and the searcher group (23 copies) about 99%, so the Ritual engine is rarely dead on turn 1. Its conversion ceiling comes from the Ritual loop (Lo, Saffira, Skull Guardian at up to 4100 ATK, Murakumo) and Extra Deck closers, but the median is unmeasured because no boards were recorded, so the score does not rely on the ceiling. Interaction is real but thin: Droll & Lock Bird, Maxx "C", Mitsurugi Great Purification, Sauravis and Radiance cover the main threats, while Ash Blossom & Joyous Spring, a 100%-inclusion staple, is absent. Nadir Servant and Dogmatika Maximus both block Extra Deck Special Summons for the rest of the turn, which conflicts with the 15-card Extra Deck plan and is penalised as an engine conflict. Popularity and archetype usage did not earn points, the score was not derived by averaging card scores, and no side deck or meta sample exists, so Meta Power is null and D12 and D13 are low or provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 64, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: banlist exposure (-1); engine conflict (-2); engine compactness (-2). Final formula: 0.80*Structural(meta-neutral, D13 dropped and renormalized to 60.3) + 0.20*TournamentReliability(60) + ContextModifiers(-5) = 55.2 -> 55 (Meta provisional)

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

• Searcher density (23 cards) and the archetype core make the engine almost always live by turn 1
• Ritual loop with GY recursion (Blessing, Radiance, Saffira, Mitsurugi Mirror) regenerates resources across turns
• High closing ceiling: Skull Guardian at 4100 ATK with Lo, Murakumo at 3200 ATK, Chaos Angel and Super Starslayer in the Extra Deck

Weaknesses

• No recorded boards, so the median output and power distribution are unknown
• Only three hand traps and no Ash Blossom, a 100%-inclusion staple
• Engine conflict: Nadir Servant and Dogmatika Maximus lock Extra Deck Special Summons
• Low archetype purity (25.5%) and many conditional Ritual Spells reduce consistency
• No side deck, so there is zero post-game adaptation

Critical choke points

• Lo or the Ritual Spell needed for Skull Guardian and Murakumo; one copy of Lo in hand is a single point of failure for the key line
• Mitsurugi Ritual, Mitsurugi Mirror and Mitsurugi Prayers each require a Reptile monster or specific resource to function

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0 is legal for Master Duel (range 40-60 / 0-15 / 0-15); All five Limited or Semi-Limited cards are run at or below their legal copies; Extra Deck breakdown: 3 Fusion, 6 Link, 4 Synchro, 2 Xyz; Exact-name archetype purity is 25.5%
• Observed: Core-card inclusion stats exist for 35 archetype rows; 15 flagged present
• Inferred: Opening-hand consistency from hypergeometric estimates; Going-first and going-second interaction ratings from card text; Engine-conflict penalty from Nadir Servant and Dogmatika Maximus text; Structural and final scores
• Provisional: Matchup and format fit (D13), since no dated meta sample exists; 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 Usage-statistics in_this_deck flags conflict with the card list: Herald of the Arc Light, Elder Entity N'tss, Wind Pegasus @Ignister, Chaos Angel, Dyna Mondo, ASHLAN U1000 and S:P Little Knight are in cards[] but flagged false. The reported core_present_pct of 60% is probably understated (about 22 of 25 after correction); treated as unreliable No win-rate telemetry; Meta Power is Provisional Guide snippet describes a Braindead / Fusion-centred Voiceless Voice variant that differs from this list
