Phantasm Spiral Deck #763857 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Stun, Control
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Summon Level 10 Sacred Beast Fusion, Xyz and Link monsters (Chaotic Phantasmal Sacred Beasts, Raviel, Uria, Hamon, Gustav Rocket) to overwhelm the board with 4000-5000 ATK boss monsters; Gustav Max and Gustav Rocket Xyz pressure with Mercurium and Underworld Goddess as board-control links
• Turn 1 (going first): Open on Sacred Beast searchers (Card of the Soul, Sacred Beasts Released, Hamon/Raviel self-searchers) to reach a Level 10 Sacred Beast and call a Phantasm boss; use Ash Blossom and Droll to protect the Summon if the opponent responds
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre and Droll as hand traps against the opponent's first Summon or search, then rebuild the Sacred Beast engine through Summoner and Mulcharmy draw effects
• Recovery: Mulcharmy Fuwalos and Purulia refill the hand when the board is empty; Sacred Beasts Released and Martyr of the Sacred Beasts rebuild the Level 10 monster count from the GY and Deck
• After siding: Not evaluable: the deck runs zero side cards, so there is no post-side plan in the export

Why it scores here

The score comes from the system, not from averaging card scores or from Phantasm Spiral being a popular archetype. The 13 archetype-core copies give about a 76% chance of at least one core card in a 5-card opening hand, and 20 searcher-text cards give about a 91% chance of a search effect (Inferred from hypergeometric estimates). Interaction is dense: Ash Blossom, Ghost Ogre, Droll, Solemn Judgment, Anti-Spell Fragrance, Crossout Designator and Harpie's Feather Duster give layered answers, and about 76% of going-second 6-card hands hold a hand trap. The boss monsters (4000 to 5000 ATK) give strong closing power. However, the list is illegal: three Forbidden cards, two Semi-Limited or Limited copy overages, and an empty Side Deck. Those issues cap the score and make this a theoretical, structural-only read. No combos or win-rate data exist, so the floor and median are unmeasured.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Control secondary (not applied as a separate blend; the Midrange profile was used directly). Structural ≈ 58.5, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-12); empty_side_deck (0). Final formula: Pre-cap: 0.80*58.5 + 0.20*45 + (-12 banlist modifier) = 43.8. Illegal deck, so the final score is capped at 30 (theoretical/structural only). Meta is provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.76 · 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

• Dense hand-trap and negate layer (Ash, Ghost Ogre, Droll, Solemn, Anti-Spell)
• High-ATK Level 10 boss monsters with a repeatable Sacred Beast summoning engine
• Strong searcher and draw density for resource recovery

Weaknesses

• Illegal in OCG: three Forbidden cards and several copy overages
• Empty Side Deck gives no post-side plan
• Long, decision-heavy combo routes with unmeasured floor and median output

Critical choke points

• Level 10 Sacred Beast count is a single point of failure for most boss summons
• Forbidden cards removed from the list break part of the interaction suite

Recommended changes

Evidence & confidence

• Verified: Main 55 and Extra 15 are within the OCG size rules (40-60 / 0-15); Called by the Grave, Triple Tactics Talent and Varudras are Forbidden in OCG; Ash Blossom & Joyous Spring is Semi-Limited (2 max) and Droll & Lock Bird is Limited (1 max); the list runs 3 and 2 copies; Boss stats: Raviel and Hamon 4000 ATK, Chaotic 5000 ATK, Gustav Rocket 5000 ATK
• Inferred: P(at least 1 archetype-core card in 5-card hand) = 0.76; P(at least 1 searcher-text card in 5-card hand) = 0.91; About 76% of going-second 6-card hands contain a hand trap; Engine consistency and brick rate are estimates from composition and text
• Provisional: Meta Power (null) and the matchup read (D13) need a 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 match record absent no win-rate telemetry (going-first/second, matchup, brick/starter/OTK rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null Side Deck is empty (0 cards) Deck is Illegal (copy limits and Forbidden cards), so the score is capped and structural-only
