Crystal Beast Deck #707328 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, FTK/Alternate-Win
• Format: ocg

Legality

Main 40 / Extra 5 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ultimate Crystal / Rainbow Dragon line (Rainbow Dragon, Rainbow Overdragon, Ultimate Crystal Rainbow Dragon Overdrive) producing 4000 ATK boards from Crystal Beast engine plays (Inferred from card text); Link and Xyz pressure from Trackblack and the Forbidden Link/Xyz slots, which cannot be played legally in OCG as built
• Turn 1 (going first): Open a Crystal Beast starter (Sapphire Pegasus, Crystal Promise, Crystal Bond, or Crystal Master) with Rainbow Bridge or Ancient City support, then chain Spell and Trap Zone Crystal Beast placements toward Golden Rule and Ruby Carbuncle (Inferred)
• Turn 2 (going second): Hand of 6 with the same starter set; the deck has no hand traps, so going second relies on Crystal Miracle and Ancient City protection and removal text (Inferred)
• Recovery: Recursion from GY through Crystal Miracle banish text, Crystal Bond re-search, and Crystal Beast monsters returned to the Spell and Trap Zone when destroyed (Inferred from card text)
• After siding: No Side Deck is registered (side_count 0), so no post-side plan exists in this list

Why it scores here

The list is Illegal in OCG: Number 60 and Saryuja Skull Dread are Forbidden and each run one copy, so the deck does not receive a normal contextual score and is capped at 25 as a structural-only read. Structurally, the Crystal Beast core is dense (18 core-group copies give about 0.96 odds of at least one in a 5-card opening hand) and the engine has redundant recursion through Crystal Bond, Ruby Carbuncle and Crystal Miracle, so consistency is moderate rather than poor. The Rainbow Dragon line supplies a real ceiling, but there are no recorded boards, so median output, going-second performance and side plans cannot be verified and stay low-confidence. Popularity on the archetype usage table (56% core present) was not credited as power, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Midrange secondary, disclosed; structural weights are the Combo profile only. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-12). Final formula: Uncapped: 0.80*Structural(51.5) + 0.20*TournamentReliability(45) + ContextModifiers(-12) = 38.2; Illegal deck capped at 25, structural-only read (Meta provisional)

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 Crystal Beast core with 0.96 odds of at least one core card in a 5-card hand (Inferred)
• Several recursion routes from GY and Spell and Trap Zone, including Crystal Bond and Crystal Miracle (Inferred)
• High-ATK ceiling with Rainbow Dragon and Rainbow Overdragon (Verified card stats)

Weaknesses

• Illegal in OCG as built because of two Forbidden Extra Deck cards (Verified)
• No Side Deck (Verified)
• No recorded boards, so median output and going-second performance are unmeasured (Verified gap)

Critical choke points

• Starter access depends on the 3-copy Pegasus, Promise, Bond and Master set, roughly 0.34 each in an opening 5 (Inferred)
• Rainbow Dragon's special summon condition of 7 different Crystal Beast names in field and GY (Verified card text)

Recommended changes

Evidence & confidence

• Verified: OCG legality: Number 60 and Saryuja Skull Dread are Forbidden and each run one copy; Main Deck 40 cards and Extra Deck 5 cards are within OCG size rules; Archetype exact-name purity is 64.4 percent; Card text for Rainbow Dragon, Rainbow Overdragon and Crystal Miracle as supplied
• Observed: Archetype usage table: 9 of 16 core cards present (56.2 percent)
• Inferred: Starter access probabilities from the hypergeometric draw table; Consistency and brick estimates from composition and card text; Strategy classification as Combo with Midrange secondary
• Provisional: Meta and format-fit placeholder for D13; Going-second performance without win-rate data
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry exists in YGOVN for going-first, going-second, matchup or brick rates Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck registered, so D12 is based on absence rather than a post-side test
