Phantasm Spiral Deck #758712 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Stun
• Format: ocg

Legality

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

Identity & game plan

• Win condition: Yubel and Fiendsmith board pressure converted through Fiend Link and Fusion Extra Deck monsters (structural read only; no recorded boards); Hand-trap and removal interaction to protect a Fiend board and win the long game
• Turn 1 (going first): Open a Yubel or Spirit of Yubel starter, use Nightmare Throne or Opening of the Spirit Gates to fetch the next Yubel piece, then extend into a Fiend Link (inferred from card text only)
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Ghost Ogre, Maxx C) to answer the opponent's first engine, then rebuild through Dark Beckoning Beast or Yubel recursion (inferred)
• Recovery: Recover through Yubel searches from Nightmare Throne and Nightmare Pain, and Yubel recursion from the GY (inferred from text; no recorded lines)
• After siding: No side deck is registered, so there is no post-side plan; the list cannot be played best-of-3 as built

Why it scores here

The deck is Illegal in OCG: five cards (Triple Tactics Talent x2, Aerial Eater, Reprodocus, Varudras, D/D/D Wave High King Caesar) are Forbidden and over the copy limit, so it receives a capped, structural-only score and not a normal Final Contextual score. Its core Yubel and Spirit of Yubel engine is reasonably accessible, with about a 65% chance of at least one archetype-core card in a 5-card opening hand (Inferred), and its 15 hand traps give good going-second coverage. The main deck is padded with 23 tech cards and spans several unrelated sub-archetypes (Unchained, Salamangreat, Muckraker, D/D), which lowers coherence, brick resistance, and Extra Deck efficiency. No combos, guides, tournament data, or side deck were supplied, so the ceiling and median are text-only inference, and the score was not derived from averaging card scores or from archetype popularity.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 50, Going First ≈ 45, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist exposure (-10); multi-archetype engine conflict (-2). Final formula: Illegal cap: theoretical structural-only. 0.80*Structural(50) + 0.20*TournamentReliability(30) + modifiers(-12) = 28, capped to 20 because the list is Illegal.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.65 · key two-card combo ≈ — · full-brick estimate ≈ 0.35 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Yubel and Spirit of Yubel provide a recursive DARK Fiend engine (Verified card text)
• 15 hand traps give strong going-second interaction (Verified card text, Inferred coverage)
• Core archetype cards are present at reasonable access rates (Inferred)

Weaknesses

• Illegal list: five Forbidden cards over the copy limit (Verified)
• No side deck, so no best-of-3 plan (Verified)
• Large tech and off-engine load dilutes consistency (Inferred)
• Multi-archetype Extra Deck lacks a single coherent link route (Inferred)

Critical choke points

• Access to a Yubel or Spirit of Yubel starter in the opening hand (Inferred)
• Single-copy Limited staples (Fiendsmith Lacrima, Fiendsmith Engraver, Phantom of Yubel) are unrecoverable if removed (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal with 5 Forbidden over-limit cards; Main 55, Extra 15, Side 0 counts; Card texts for Yubel, Spirit of Yubel, Nightmare Throne, Solemn Judgment, Ash Blossom
• Inferred: Starter access 0.65 from the hypergeometric core-group estimate; Brick proxy 0.35; Going-second hand-trap coverage 0.87; Combo and interaction reads from card text
• Provisional: Meta and matchup fit (no dated metagame sample or tournament data)
• 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 side deck registered No win-rate telemetry exists in YGOVN; going-first and going-second splits are Inferred Meta Power is Provisional unless a dated metagame sample is supplied
