Neo-Spacian Deck #789846 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 43/100 (±8 · Confidence: Medium)

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

Legality

Main 41 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion Summon Neos-line boards from the Extra Deck, such as Chaos Neos, Storm Neos, Nebula Neos or Shining Neos Wingman, to take over the board.; Yubel-based pressure through Neos Kluger and Yubel - The Loving Defender Forever, with Honest Neos and Spirit of Neos as extra attackers.
• Turn 1 (going first): Open with Neos, a Polymerization or a searcher (E - Emergency Call, Vision HERO Vyon, Spirit of Neos), then convert the hand into a Neos-line Fusion Summon on turn 1 or 2.
• Turn 2 (going second): Use the six-card hand to search Polymerization or Super Polymerization, Fusion Summon through the opponent's board, and rebuild with Vyon and Ejector recursion from the Graveyard.
• Recovery: Re-search Polymerization with Vision HERO Vyon by banishing a HERO monster from the Graveyard, then use Spirit of Neos and Miracle Ejector to add pieces back to hand.
• After siding: No side deck is registered, so there is no post-side plan; every game is played with the main deck as built.

Why it scores here

The deck is a Fusion-driven HERO and Neo-Spacian list whose consistency rests on its searchers and Polymerization effects rather than on any single card: Neos is only 33% likely to appear in a going-first opening hand, so access to the engine depends on the searchers (about 87% chance of at least one in an opening hand). Its ceiling is high, because the Extra Deck holds several 3000-ATK Neos-line Fusion monsters and Yubel. Its median output is weaker, since 27 of 41 main-deck cards are Elemental HERO, the Vision and Evil HERO and Neo-Spacian sub-archetypes are mixed in, and Rainbow Dragon and Rainbow Neos need Crystal Beast or Ultimate Crystal support that the list does not carry. Interaction is thin: there are no hand traps and the removal and negation text comes mostly from Fusion monsters and single copies. The score is built from consistency, median output and interaction on the whole system; popularity or archetype usage did not add points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange (D13 dropped and renormalized over 95). Structural ≈ 49, Going First ≈ 45, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: No side deck (-3); Dead main-deck cards (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*49.2 + 0.20*45 = 48.4, minus 5 modifiers = 43.4

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.33 · 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 and recursion text (13 searchers) gives many routes to Polymerization and Neos
• 14 Fusion monsters with 3000-ATK ceilings and Yubel give real closing power
• Single-copy Super Polymerization is legal (2 allowed) and adds a second Fusion route

Weaknesses

• Neos is a single-card choke point: three copies in a 41-card deck
• No side deck, so no post-side plan
• Rainbow Dragon and Rainbow Neos are effectively dead cards with no support
• Low archetype purity: the HERO family is mixed with Vision, Evil and Neo-Spacian pieces

Critical choke points

• Neos in hand or reachable by search (33% per going-first opening hand)
• Polymerization and Super Polymerization as the only generic Fusion enablers
• Vyon's Graveyard banish cost for Polymerization recovery

Recommended changes

Evidence & confidence

• Verified: Legality: 41 main, 15 extra, 0 side; Super Polymerization is Semi-Limited at 1 of 2 copies; Card text for the Neos line, Vision HERO and Neo-Spacian cards; Archetype mix counts from the main deck
• Inferred: Neos access probabilities (0.33 going first, 0.386 going second); Structural scoring and interaction read from card text; Extra Deck ceiling compared with the median
• Provisional: Meta and format fit (no dated metagame sample or tournament link)
• Data gaps: no recorded boards: combo ceiling, median and floor are text-only inference no tournament link: archetype meta-share and any pilot record are absent no side deck registered: post-side plan cannot be assessed Core-card matching marks Extra Deck cards such as Masked HERO Dark Law, Xtra HERO Wonder Driver and Favorite HERO Flame Wingman as absent even though they are in the Extra Deck list; the 24% core-presence figure is therefore unreliable and was not used No win-rate telemetry exists in YGOVN; going-first, going-second, matchup and brick rates are Inferred or Unknown
