Phantasm Spiral Deck #774152 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±12 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange
• 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: Sacred Beast Level-10 ascension into Raviel / Chaotic Phantasmal Sacred Beasts and Gustav Rocket pressure (text-only read; no recorded boards); Ghostrick Angel of Mischief Xyz line (2 copies) and Number 35 / Tistina board pressure
• Turn 1 (going first): Normal Summon Martyr of the Sacred Beasts (Level 1), place a Sacred Beast Field Spell or Continuous Spell/Trap, then ascend into Sacred Beast Level-10 Special Summons (Calamity, Raviel, Uria) via Thunderclap / Released searches
• Turn 2 (going second): Hold Ghost Ogre & Snow Rabbit / Nibiru / Buio as hand interaction, then rebuild the Sacred Beast Level-10 line through the same Martyr and Released search chain
• Recovery: Recycle Sacred Beast monsters from the GY via Martyr, Summoner and Fallen Paradise (send 3 cards of one type to GY, then Special Summon a Sacred Beast from GY or banishment)
• After siding: None: the deck registers no Side Deck, so there is no post-side plan (Verified: side_count 0)

Why it scores here

The deck's score comes from its system, not from averaging card scores: Martyr of the Sacred Beasts, Sacred Beasts Thunderclap and Sacred Beasts Released (3 copies each) plus 22 searcher-text cards give a high chance (about 0.96 for at least one archetype-core card in a 5-card opening hand, Inferred) of finding an engine piece. Recursion through Martyr, Summoner, Uria and Fallen Paradise gives reasonable interruption resilience (Inferred from card text). Interaction is real but thin: 7 negation-text and 25 removal-text cards, with 4 hand traps, mostly as Level-10 summon-enablers rather than a dedicated stun suite. No combos, tournament results, or guides were supplied, so the combo ceiling and floor are text-only inference and the score cannot be pinned to observed boards. Popularity and archetype usage stats confirm the list is real and accessible but earned no points. The deck is Illegal (Varudras is Forbidden and run 1 copy), so the Final score is capped low and this evaluation is theoretical/structural-only; the deck also has no Side Deck.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-12). Final formula: No metagame sample: 0.80*Structural(57) + 0.20*TournamentReliability(42) = 54; banlist modifier -12 gives 42; Illegal-deck cap applied to 30 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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 Sacred Beast engine with 3-copy Martyr, Thunderclap, Released and Calamity
• 22 searcher-text cards for consistent engine access
• Multiple GY recursion routes for restarts
• Large Level-10 boss pool (Raviel, Chaotic Phantasmal, Gustav Rocket) for closing

Weaknesses

• Illegal list: Varudras is Forbidden and run 1 copy
• No Side Deck, so zero post-side plan
• Level-10 summon conditions make the engine hard to pilot
• Off-archetype Extra Deck slots (Number, Tistina, Lyrilusc) dilute engine cohesion
• Summoner and Uria run 2 copies versus typical 1

Critical choke points

• The Sacred Beast Level-10 ascension depends on Martyr or Released resolving; disruption on Martyr early can stall the line
• Every Level-10 monster needs a Sacred Beast effect to summon, so the engine is one-chain-deep on many hands

Recommended changes

Evidence & confidence

• Verified: Illegal: Varudras is Forbidden and run 1 copy (legality block); Main 55 and Extra 15 are within size rules; Side 0 is within size rules; Gustav Max is Limited at 1 copy (legal); Core cards Martyr, Released, Thunderclap, Raviel and Calamity are each run 3 copies, matching usage stats
• Inferred: At least one archetype-core card in a 5-card opening hand ≈ 0.96; Engine accessibility and recursion from card text; Interaction density from negation and removal text; Going-first and going-second structure from text and probabilities
• Provisional: Meta Power and matchup fit (no dated metagame sample); Tournament reliability (no tournament link)
• Data gaps: Varudras is Forbidden and makes the deck Illegal, so the Final score is capped and theoretical/structural-only No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No guides for the archetype No win-rate telemetry (going-first/second, matchup, brick/starter rates) Deck has no title (deck_name null) and no Side Deck Archetype purity metric reports 0% exact-name purity for 'Phantasm Spiral'; sub-archetype spread used instead
