Centur-Ion Deck #770868 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 41 / Extra 21 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Synchro-summon a high-ATK boss (Cosmic Blazar Dragon, Centur-Ion Legatia, Centur-Ion Auxila, Arms of Genex Return Zero) from a Centur-Ion-driven board, protected by Centur-Ion continuous-trap protection; Elfnote Tinia / Elfnote Lucina board pressure with Elfnote recursion; Mulcharmy draw-punish as chip
• Turn 1 (going first): Normal Summon Centur-Ion Primera or Trudea, search a Centur-Ion or Emblema card, set up Stand Up Centur-Ion! / Wake Up Centur-Ion! for protection, then Synchro into a boss
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre & Snow Rabbit, Maxx C and Droll & Lock Bird to answer the opponent's first summon or search, then rebuild through Centur-Ion searchers
• Recovery: Recur Centur-Ion monsters from the GY through Centur-Ion Phalanx, Emblema Oath and Centur-Ion Gargoyle II, and re-Synchro from the Extra Deck
• After siding: Not defined: the deck runs 0 Side Deck cards, so there is no post-side plan in the list as submitted

Why it scores here

This list is Illegal (three Forbidden cards run at full copies and a 21-card Extra Deck over the OCG limit of 15), so its score is capped as a theoretical, structural-only read and is not a normal final score. The structural read is driven by the system: the Centur-Ion core (16 archetype copies) has about a 93% chance of at least one piece in a 5-card opening hand (Inferred), and 12 searcher-text cards make the engine reasonably accessible. Interaction is real but thin for a 41-card main: 6 hand traps and 3 negation-text cards give going-second resilience, and the Forbidden Baronne and Crystal Wing removal would have been a large part of the interaction suite, so removing them lowers the board-breaking read. Popularity and archetype-usage stats (the Centur-Ion core appears in most published lists) confirm the build is real and accessible but did not earn any points, and no card scores were averaged into the deck score. Without recorded combos, a side deck or tournament data, the ceiling, median and post-side scores are text-based Inferred estimates and the confidence is Low.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59.3, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: Banlist exposure (-10); Engine conflicts / sub-archetype spread (-2). Final formula: Illegal cap applied. Structural = Σ(score×weight)/100 = 59.3; no-meta Final = 0.80×59.3 + 0.20×48 = 57.0; modifiers −12 gives 45.0; capped at 35 because the list is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · key two-card combo ≈ — · full-brick estimate ≈ 0.07 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Centur-Ion core (16 copies) is highly accessible in an opening hand
• 12 searcher-text cards and GY recursion give resource recovery
• Strong Synchro bosses with 3000 to 4000 ATK and removal or negation text
• Six hand-trap cards give going-second resilience

Weaknesses

• Illegal list: three Forbidden cards at full copies
• Extra Deck of 21 exceeds the maximum of 15 by 6
• No side deck, so no post-side plan
• Low archetype purity (22.6%) and mixed sub-archetypes reduce engine coherence
• Mulcharmy draw-punish cards are conditional and can be dead

Critical choke points

• The Centur-Ion Synchro boss must be summoned from the Extra Deck, so the Extra Deck legality failure directly affects playability
• Centur-Ion protection relies on Stand Up Centur-Ion! and Wake Up Centur-Ion!, so losing them to a single interruption can leave bosses exposed

Recommended changes

Evidence & confidence

• Verified: Legality status is Illegal: 3 Forbidden cards run; Extra Deck 21 exceeds the maximum of 15; Main Deck size 41 is within the OCG range of 40 to 60; Archetype purity 22.6%; 17 Synchro and 4 Fusion Extra Deck cards
• Observed: Centur-Ion core inclusion is high in published archetype usage (usage stats, context only)
• Inferred: Opening-hand probabilities: core ≈ 0.93, searcher ≈ 0.84, hand-trap ≈ 0.64; Consistency, resilience and going-second read from card text; Board ceiling from Synchro boss stats and text
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link
• Data gaps: Illegal list: scoring is a theoretical, structural-only read and the final score is capped No recorded combos, so ceiling, median and board metrics are text-based inference No side deck, so post-side adaptability cannot be assessed No tournament link; archetype meta-share and per-pilot records are absent No win-rate telemetry; going-first and going-second splits are Inferred Meta Power is Provisional without a dated metagame sample
