Crystal Beast Deck #773070 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fusion Summon Elemental HERO / Neos / Masked HERO boss monsters (e.g. Cosmo Neos, Shining Neos Wingman, Contrast HERO Chaos) off searcher-driven starts.; Link and Masked HERO follow-ups (Xtra HERO Wonder Driver, Masked HERO Acid, Masked HERO Blast) once the board is established.
• Turn 1 (going first): Open a searcher (Miracle Ejector, Stratos, Vyon, Furnace) and use Polymerization / Miracle Fusion / Mask Change to reach a Fusion boss, protected by Forbidden Droplet or Infinite Impermanence.
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird and Infinite Impermanence to stop the opponent's first engine, then rebuild through the searchers.
• Recovery: Recover Polymerization, Mask Change and HERO monsters from the GY (Vision HERO Vyon, Masked HERO Fountain, Mask Change in Deck or GY).
• After siding: No Side Deck is registered, so no post-side plan can be evaluated.

Why it scores here

The deck is scored as a system, not as an average of its cards. Its fusion engine depends on a single copy each of Polymerization, Miracle Fusion and Mask Change, so the opening-hand probability of a live fusion starter is only moderate, and the 14 searcher-text cards carry most of the consistency. Interaction is the strongest area: three Ash Blossom and three Infinite Impermanence, Forbidden Droplet, Forbidden Crown and Droll & Lock Bird give layered answers, with a 57% chance of at least one hand trap when going second. The ceiling (Cosmo Neos, Chaos, Wingman) is high, but no recorded boards exist, so the median output is inferred and low confidence. Crystal Beast popularity earned no points: the declared archetype has zero exact-name cards, and the list is an Elemental HERO / Masked HERO build. The list is Illegal (three Ash Blossom against a two-copy OCG limit), so the final score is capped and labelled structural-only.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Combo context not weighted in the structural sum. Structural ≈ 51, Going First ≈ 45, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: Illegal cap applied: 0.80*51 + 0.20*38 = 48.4, then modifiers -12 gives 36.4, capped to 30 (theoretical/structural-only; Meta Provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · 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

• Layered interaction: Ash Blossom, Infinite Impermanence, Forbidden Droplet, Forbidden Crown, Droll & Lock Bird
• Searcher density (14 searcher-text cards) keeps the engine accessible
• Extra Deck covers high-ATK HERO and Neos bosses

Weaknesses

• Illegal copy count on Ash Blossom & Joyous Spring
• Declared archetype (Crystal Beast) does not match the list: 0 exact-name copies, mostly HERO
• Single-copy fusion enablers (Polymerization, Miracle Fusion, Mask Change)
• No Side Deck

Critical choke points

• Only one Polymerization, so fusion access depends on Miracle Ejector / Stratos / Vyon searches and Favorite Contact
• Hand-trap dependence when going second (57% at least one in 6 cards)

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring: 3 copies vs 2 legal (OCG Semi-Limited); Main 56 and Extra 15 within size rules; Side 0 is legal; Card text and stats for all 56 Main and 15 Extra cards
• Observed: Usage stats show Crystal Beast core inclusion 75%; this list has 0 of 5 core cards except Forbidden Droplet
• Inferred: P(>=1 starter in opening 5) ≈ 0.78 for the searcher group; Consistency, brick and interaction-density reads from text; Going-second hand-trap probability ≈ 0.57
• Provisional: Meta Power (no dated sample); Matchup and format fit (no tournament link)
• 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 rates) in YGOVN Meta Power is Provisional without a dated metagame sample Deck title is null and the declared archetype does not match the list No Side Deck registered, so post-side behaviour is unknown
