Mecha Phantom Beast Deck #772030 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Radiant Typhoon / Roid quick-play engine converting into a Synchro or Link boss (Fonix, Crystal Clear Wing Over Synchro Dragon, Accel Synchro Stardust Dragon); Clear Wing negation-backed boards
• Turn 1 (going first): Quick-Play activation or searcher (Terrortop, Swen, Eldam) into Mystical Space Typhoon, then Synchro the Radiant Typhoon board
• Turn 2 (going second): Ash Blossom, Maxx C and Droll & Lock Bird to break the opponent's first combo, then rebuild through Quick-Play engines
• Recovery: Recycle Quick-Play spells through Radiant Typhoon Mandate and re-search with the Radiant Typhoon monsters
• After siding: No side deck (0 cards): no post-side plan exists as built

Why it scores here

As built the list is illegal in OCG: three Forbidden Extra Deck cards and three copies of a Limited Quick-Play spell, so its score is capped and read as structural-only. Structurally the deck has a real engine: 19 searcher-text cards, a Quick-Play trigger package (Mystical Space Typhoon, Radiant Typhoon monsters) and a broad synchro and link Extra Deck that gives it several boss options. Its weaknesses are the 3.6% exact-archetype purity (53 off-archetype copies across roughly five sub-archetypes), three dead Extra Deck slots, and a zero-card Side Deck that leaves no post-side plan. Popularity of the Radiant Typhoon and Mecha Phantom Beast names did not earn points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Toolbox secondary; weights not tuned to force a score. Structural ≈ 48.7, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: Illegal cap: theoretical/structural-only. Unclamped 0.80*Structural + 0.20*TournamentReliability + modifiers = 0.80*48.7 + 0.20*45 − 12 ≈ 36; capped to 30. Meta provisional, not used.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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 searcher text (19 cards) gives card economy
• Layered negation: Ash Blossom, Maxx C, Droll & Lock Bird, Clear Wing, Crystal Clear Wing
• Strong closing bodies: Fonix and Crystal Clear Wing Over Synchro Dragon

Weaknesses

• Illegal as built: 3 Forbidden Extra Deck cards and 3 copies of a Limited spell
• No side deck
• Low exact-archetype purity (3.6%)

Critical choke points

• Mystical Space Typhoon in hand as the Quick-Play trigger for the Radiant Typhoon package
• Three dead Extra Deck slots after banlist correction

Recommended changes

Evidence & confidence

• Verified: Legal size counts: 40 main, 15 extra, 0 side vs OCG rules; Forbidden status for Auroradon, Baronne de Fleur and Albion; Radiant Typhoon Chant Limited status with 3 copies run
• Inferred: Consistency estimates from hypergeometric draw table; Negation and removal roles read from card text; Going-first and going-second estimates
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
