Phantasm Spiral Deck #730353 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Fusion, Link, Ritual
• Format: ocg

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Special Summon Sacred Beast Level 10 boss monsters (Raviel, Hamon, Uria, Chaotic Phantasmal Sacred Beasts) via Phantasm and Sacred Beast chains, then attack or destroy through the opponent's board; Ritual and Fusion/Link end boards (Black Chaos, Magician of Dark Chaos, Armityle, Fiendsmith's Lacrima) for board presence
• Turn 1 (going first): Search or discard a Sacred Beast starter (Opening of the Spirit Gates, Dark Beckoning Beast, Calamity of the Sacred Beasts) into a Level 10 Special Summon; hold Ash Blossom and Droll for the first interruption
• Turn 2 (going second): Use Ash Blossom, Droll and Maxx C as hand traps to break the opponent's first combo, then rebuild a Sacred Beast board from the GY through Martyr and Fallen Paradise (Inferred, no going-second data)
• Recovery: Recycle from GY with Martyr of the Sacred Beasts, Abyss of the Sacred Beasts and Fallen Paradise of the Sacred Beasts; Sacred Beasts Released is a GY recursion search (Inferred)
• After siding: Not available: the deck has 0 side cards, so there is no post-side plan

Why it scores here

The deck reliably finds a starter: 30 searcher-text cards give about 97% odds of at least one searcher in the opening 5, and the archetype core (12 copies) gives about 69% of at least one core card. Its ceiling comes from Level 10 Sacred Beast boss monsters, Raviel, Hamon, Uria and Chaotic Phantasmal, which can end a board. Interaction is layered: 4 hand traps plus negation and removal text. The deck scores as a system and not by averaging its cards: the consistency and interaction come from its redundant searchers and hand traps. It is capped low because three Forbidden copies make the list illegal, so the score is theoretical only. Its popularity in the archetype does not raise the score, and there is no combo data, so the ceiling and median are text-based inferences.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 55, Going First ≈ 60, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-10); no side deck (-2). Final formula: Illegal cap: 0.80*Structural(55) + 0.20*TournamentReliability(45) = 53, minus 12 modifiers = 41, capped to 25 because the deck is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.69 · key two-card combo ≈ — · full-brick estimate ≈ 0.31 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Redundant searchers (30 cards) and multiple Sacred Beast starters give high engine access
• Level 10 boss monsters give a high ceiling and closing power
• Layered interaction: 4 hand traps plus negation and removal text

Weaknesses

• Three Forbidden copies make the list illegal
• No side deck, so there is no post-side adaptability
• Conditional Special Summon routes make the floor fragile
• Heavy reliance on archetype-specific monsters causes bricks

Critical choke points

• Opening Sacred Beast starter (Opening of the Spirit Gates, Dark Beckoning Beast, Calamity) gates the whole line
• Forbidden cards must be removed before the list can be played at all

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: 3 Forbidden copies over the copy limit (legal copies 0); Main 60, Extra 15, Side 0 within OCG size rules; Limited and Semi-Limited copy counts are legal; Card text and stats from the resolved card list; Searcher-text count of 30 and removal-text count of 20; Archetype stats: 6 of 11 core cards present (54.5%)
• Inferred: Consistency estimates (hypergeometric: searcher 0.97, core 0.69, proxy full-brick 0.31); Ceiling and interaction ratings from card text; Going-first and going-second estimates from hand-trap and starter count
• Provisional: Meta Power (null, no dated metagame sample); Matchup fit (D13 at 50, no meta share)
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot record are absent No win-rate telemetry exists in YGOVN (going-first/second, matchup, brick and OTK rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null in the export
