Crystal Beast Deck #756288 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ultimate Crystal Fusion/Special Summon of Rainbow Dragon, Rainbow Overdragon, or Ultimate Crystal Rainbow Dragon Overdrive (4000 ATK) after the Crystal Beast field is built through Crystal Bond, Rainbow Bridge and Awakening of the Crystal Ultimates; Xyz and Synchro beatdown with Crystal Beast monsters and Utopia Xyz monsters once a Crystal Beast board is established
• Turn 1 (going first): T1: Crystal Bond or Rainbow Bridge to find a Crystal Beast or Crystal S/T, followed by Crystal Beacon or Rainbow Bridge of the Heart to build the Continuous Spell line, then a Normal Summon to reach the Ultimate Crystal Summon condition
• Turn 2 (going second): Respond to the opponent's board with Crystal Miracle or Crystal Conclave while using the Crystal Beast revival loop, then rebuild with Rainbow Dragon or Rainbow Overdragon if the field is still alive
• Recovery: Crystal Beast monsters returned to the Spell & Trap Zone as Continuous Spells and the GY-based Crystal Miracle/Revolution Synchron recursion let the deck rebuild from the GY after a single board break
• After siding: No Side Deck is registered, so no post-side plan can be evaluated

Why it scores here

The deck reliably opens its Crystal Beast core: the archetype-core group has about an 88% chance of at least one copy in a 5-card opening hand, and 16 searcher-text cards add redundant access. Its conversion ceiling is high because the Ultimate Crystal Extra Deck options (Rainbow Overdragon, Rainbow Dragon, Ultimate Crystal Rainbow Dragon Overdrive) reach 4000 ATK, and Crystal Beast recursion from the GY and Spell & Trap Zone lets the deck survive a single board break. The median output is far weaker than the ceiling: there are no recorded boards, and 34 of 40 Main Deck copies are off the exact archetype name, so the list depends on a few lines rather than a consistent floor. Interaction is thin (3 negation-text cards and no hand traps), and there is no Side Deck, so going-second play and post-side adaptation score low. The score is capped because the list runs two Forbidden cards (Graceful Charity and Number 60), so this is a structural-only read and no normal contextual score is given. Popularity and the archetype's usage statistics were not used as points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange 100% (Combo secondary disclosed, not blended). Structural ≈ 55, Going First ≈ 55, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-12); illegal_deck_cap (0). Final formula: Structural 55 -> 0.80*55 + 0.20*50 = 54 before modifiers; modifiers -12 gives 42; Illegal-deck cap sets the final score to 20 (theoretical/structural-only, no normal contextual score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · key two-card combo ≈ — · full-brick estimate ≈ 0.12 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype-core access is high (about 88% at least one in a 5-card hand)
• Redundant searchers (16 searcher-text cards)
• Crystal Beast recursion from GY and Spell & Trap Zone
• Three 4000-ATK finishers in the Extra Deck

Weaknesses

• Two Forbidden cards in the Main Deck make the list illegal
• No Side Deck
• Low exact-archetype purity (38.2%) and many off-archetype singletons
• Thin interaction with no hand traps or floodgates
• No recorded boards, so the median output is unverified

Critical choke points

• Ultimate Crystal Fusion/Special Summon condition depends on a Level 10 Ultimate Crystal monster (Rainbow Dragon)
• Crystal Beast board requirement of 7 different names for the 4000-ATK summons
• Forbidden Graceful Charity and Number 60 consume hand and Extra slots that must be removed before the list can be played

Recommended changes

Evidence & confidence

• Verified: Illegal status: Graceful Charity (2) and Number 60 (1) are Forbidden in OCG; Main 40, Extra 15, Side 0 counts; Exact-name archetype purity 38.2%; Core-group hypergeometric estimate 0.8773 at 5 cards; Extra Deck split: 9 Xyz, 3 Synchro, 3 Fusion
• Inferred: Consistency estimate (P at least one starter) and proxy brick rate; Ceiling read from card text of the Ultimate Crystal finishers; Interaction density from negation and removal text; Going-second weakness from absent hand traps and Side Deck
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13)
• Data gaps: no combos supplied; floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied Side Deck is empty, so no post-side evidence exists
