Crystron Deck #772684 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Synchro and Xyz boards led by Crystron Quariongandrax (3000), Crystron Eleskeletus (2600) and Vermillion/Navy/Jade Dragon Mech (2700), with Crystron recursion from GY and banish zones; Crystron Ametrix and Samurai Destroyer as additional Synchro bosses that also disrupt or negate
• Turn 1 (going first): Open a Crystron starter (Sulfefnir, Smiger, Sulfador, Inclusion) and start Synchro lines while holding hand traps for the opponent's first board
• Turn 2 (going second): Use the 15 hand traps and Ash Blossom, Ghost Ogre, Ghost Belle, Effect Veiler and Nibiru to stop the opponent's engine, then rebuild the board with Crystron recursion
• Recovery: Recurse Crystron monsters from the GY or banishment through Crystron Smiger, Thystvern, Prasiortle and Inclusion, and rebuild Synchro summons from the remaining board
• After siding: Not evaluable: the deck has no side deck (Side Deck size 0), so no post-side plan exists in the evidence

Why it scores here

The deck opens a Crystron engine reliably: 25 archetype-core copies give about a 96% chance of at least one core card in a 5-card opening hand, and eight Crystron starters and recursion pieces give several independent lines. Its 15 hand traps and 18 negation-text cards give it strong going-second interaction and layered protection for its Synchro board. Conversion is real but mostly structural, since no combo boards were recorded, so ceiling and median are both inferred from card text. Popularity and archetype usage were not credited, and card scores were not averaged. The deck is Illegal (Ash Blossom at 3 copies over a limit of 2), so the score is capped at 40 and is structural only; there is no side deck and no tournament or meta data.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Stun secondary; the Midrange profile is used for the structural score. Structural ≈ 61, Going First ≈ 55, Going Second ≈ 65, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Illegal copy-limit violation (-8); No side deck and unresolved passcode (-4). Final formula: No reliable metagame: 0.80*Structural(61) + 0.20*TournamentReliability(55) = 59.8; modifiers -12 gives 47.8; Illegal-deck cap applied, final = 40 (structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.04 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense Crystron core (25 copies) with recursion from GY and banishment
• 15 hand traps and 18 negation-text cards give strong going-second interaction
• Synchro bosses (Quariongandrax 3000, Eleskeletus 2600, Dragon Mechs 2700) that shrink or negate the opponent's board

Weaknesses

• Illegal: Ash Blossom & Joyous Spring is run 3 copies against a limit of 2
• Low Crystron purity (31.4%) with heavy splash from Mulcharmy, Penguin, Forbidden, Solemn and Cyclone
• No side deck, so no post-side plan can be measured
• No recorded combo boards, so ceiling and median are unverified

Critical choke points

• The Crystron Synchro engine depends on a few Tuners (Sulfador, Tristaros, Quandax, Citree) and on Crystron Inclusion
• Going-second hand-trap coverage depends on the same 15 interaction cards, which compete for hand space with starters

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring at 3 copies over the limit of 2; Main 55, Extra 15, Side 0 within size rules; Card text and banlist statuses for all resolved cards; Archetype purity 31.4% and Extra Deck breakdown
• Inferred: Opening-hand probabilities (hypergeometric, from the resolved list); Going-second hand-trap coverage; Resilience and recursion estimates from card text; Ceiling and median from text, since no combos were recorded
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link); Post-side adaptability (no side deck)
• Data gaps: No combos supplied, so floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and pilot record are absent One CardIDList passcode (10443957) could not be resolved and was counted as main No side deck, so post-side adaptability cannot be measured No win-rate telemetry exists for this deck Meta Power is Provisional unless a dated metagame sample is supplied
