Crystal Beast Deck #755029 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 60 / Extra 13 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Extra Deck boss beats (Crystal Beast Rainbow Dragon, Rainbow Dragon, Black Chaos, Black Luster Soldier, The Crimson King) reached through Ritual, Fusion and Synchro chains from Light and Darkness Ritual, Mitsurugi Ritual and Fallen of Albaz routes; Dragon Devours the Dogma and Albion beats via Fallen of Albaz fusion lines; Albion is Forbidden and cannot be played in this format as built
• Turn 1 (going first): Crystal Bond or Rainbow Bridge to add a Crystal Beast or Crystal searcher, Sapphire Pegasus or Mulcharmy Fuwalos for board, then a Fallen of Albaz or Mitsurugi starter into a Fusion or Ritual boss; Ash Blossom and Forbidden Droplet protect the turn
• Turn 2 (going second): Hand traps (Ash Blossom, Infinite Impermanence, Griffoh, Mulcharmy Fuwalos) to interrupt the opponent's starter, then rebuild through searchers and a Rainbow Dragon or Black Chaos Extra Deck summon
• Recovery: Crystal Beast monsters placed as Continuous Spells and recursion through Crystal Bond, Ragged Records of Rites and Mind Shuffle keep a second line alive after a broken opener
• After siding: No Side Deck is registered, so no post-side plan can be assessed; the list is structural-only

Why it scores here

The deck opens reliably on searchers: P(at least one searcher-text card in a 5-card opening hand) is about 0.97, and the archetype core (Crystal Beast, Light and Darkness Ritual, Mitsurugi, Branded and Fallen of Albaz) has about a 0.78 chance of at least one copy in hand, both Inferred from the hypergeometric draw table. Its ceiling is high because the Extra Deck holds several 3000 to 4000 ATK boss monsters and the interaction package (Ash Blossom, Infinite Impermanence, Forbidden Droplet, Crystal Bond recursion) gives it real answers, but no recorded combo boards exist, so the floor and median are text-only inference. The score is held down by a fragmented engine: only 9 of 60 Main Deck cards carry the exact Crystal Beast name (12.3% exact purity) and the list spans five sub-archetypes, which raises brick risk and pilot error. The deck is also Illegal as built, with six over-limit copies including three Forbidden cards, so the final score is capped and treated as theoretical and structural-only. Popularity was not credited, no card scores were averaged, and the deck was scored as a system.

Dimension scores

How the score was computed

Strategy profile: Combo primary with Midrange secondary; Structural computed with the Combo profile only. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 46. Modifiers: banlist_exposure (-6); engine_conflicts (-5); illegal_cap (0). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*57 + 0.20*46 - 11 = 44; Illegal-deck cap applied, final 30 (theoretical/structural-only, no normal Final Contextual score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · 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 suite (29 searcher-text cards) gives reliable access to the engine on going first
• Extra Deck bosses at 3000 to 4000 ATK with removal and negation text give strong closing power
• Layered interaction: hand traps plus Forbidden Droplet and Crystal Bond recursion

Weaknesses

• Illegal as built: six over-limit copies including three Forbidden cards
• Fragmented engine: five sub-archetypes and 12.3% exact-name purity
• No Side Deck, so no post-side adaptability

Critical choke points

• Fixing the copy limits removes Albion, Ame no Habakiri and Called by the Grave, which are key interaction and boss routes
• Engine reliance on Light and Darkness Ritual and Fallen of Albaz starters, each a single-card dependency at 1 to 3 copies

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal with six over-limit copies and three Forbidden cards; Main 60, Extra 13, Side 0 within OCG size rules; Card text and banlist statuses for all resolved cards; Archetype purity 9 of 73 Main Deck archetype-tagged copies
• Inferred: Opening-hand searcher probability ≈ 0.97 and archetype core probability ≈ 0.78; Hand-trap probability ≈ 0.48 going second; Interaction density from negation and removal text; Engine accessibility and brick risk from composition
• Provisional: Meta Power and format fit (no dated meta sample or tournament link); Post-side adaptability (no Side Deck registered)
• Data gaps: no combos supplied, so combo floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and pilot match record are absent no win-rate telemetry for going-first, going-second, matchups or brick rates Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck registered, so post-side plan cannot be assessed
