Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Ritual
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Ritual Summon a Light and Darkness Ritual boss such as Black Luster Soldier or Magician of Dark Chaos - Black Chaos, then extend through Extra Deck link and Xyz boss monsters; Horus Special Summons from the GY via King's Sarcophagus, plus Mulcharmy draw-engine pressure
• Turn 1 (going first): Open a Light and Darkness Ritual starter (Light and Darkness Ritual, Prayers of the Voiceless Voice or Mind Shuffle to find a Ritual monster), Ritual Summon a boss, and hold Ash Blossom or Droll & Lock Bird for interaction
• Turn 2 (going second): Use Ash Blossom and Droll & Lock Bird to interrupt the opponent's search or summons, then Mulcharmy draw effects and the Ritual line to rebuild board presence
• Recovery: Recover from the GY through Skull Archfiend of Chaos, Griffoh, Mind Shuffle and Radiance of the Voiceless Voice, which add Ritual or Voiceless Voice cards back to hand
• After siding: No Side Deck is registered, so there is no post-side plan. Post-side performance is unknown and cannot be scored.

Why it scores here

The deck reliably opens an engine in the core archetype: about 89 percent of hands hold at least one Light and Darkness Ritual card (Inferred, hypergeometric), and 21 searcher-text cards give it a strong search base. Its conversion ceiling comes from Ritual bosses such as Black Luster Soldier and Magician of Dark Chaos plus Extra Deck threats, but no recorded boards exist, so the median output is unverified. Interaction is layered through Ash Blossom, Droll & Lock Bird and negation text, which helps it survive a disruption. The deck is illegal as submitted: Ash Blossom runs 3 copies against a limit of 2, so the score is capped low and labeled structural-only. Popularity and archetype usage did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 51, Going First ≈ 48, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Banlist exposure (illegal copy count) (-8); Archetype incoherence (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 47.8, then illegal-deck modifiers -12 and low cap applied, giving 36

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · 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

• Core archetype access is high: about 89 percent of opening hands hold a core card (Inferred)
• Layered interaction from 7 hand traps, 8 negation-text cards and 11 removal-text cards (Verified card text)
• Strong Ritual and Extra Deck closers with 2800 to 3500 ATK (Verified card stats)

Weaknesses

• Illegal as submitted: Ash Blossom runs 3 copies against a limit of 2 (Verified)
• Low exact archetype purity (18.6 percent) and mixed Link Extra Deck (Verified)
• No Side Deck, so post-side adaptability is unknown (Verified)
• No recorded boards, so the floor and median are unmeasured (Verified gap)

Critical choke points

• Ritual starter density: only 3 Ritual Spells and about 4 Ritual monsters, so a bad opener can miss the engine (Inferred)
• Ash Blossom over the copy limit must be cut before the list can be scored as legal

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom & Joyous Spring runs 3 copies against a Semi-Limited limit of 2; main 55, extra 15, side 0; Card text and stats for the Ritual, Horus and Link monsters listed in the evidence; Exact archetype purity 18.6 percent and 21 searcher-text cards; Core archetype group P(>=1 in hand5) = 0.8916
• Inferred: Starter access and brick risk from hypergeometric draw odds; Ritual boss conversion and interaction density from card text; Going-first and going-second estimates
• Provisional: Meta Power is null; matchup and format fit are provisional with no dated meta sample; Post-side plan cannot be assessed without a Side Deck
• 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, so going-first, going-second, matchup and brick rates are Inferred or Unknown No Side Deck registered, so post-side performance is unknown Meta Power is Provisional without a dated metagame sample
