Centur-Ion Deck #775067 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Centur-Ion Synchro boards (Auxila, Legatia, Primera Primus) built through Centur-Ion Primera, Stand Up Centur-Ion!, Trudea and Emblema Oath, with Centur-Ion Gargoyle II and Atrii as the in-archetype bodies; Elfnote Synchro pressure (Elfnote June Pride, Seraphim Strelitzia, Tinia, Lucina) once a tuner and non-tuner are in the Main Monster Zone
• Turn 1 (going first): Open a Centur-Ion or Elfnote starter (Primera, Trudea, Regina) and extend into a Synchro with a tuner, while holding Infinite Impermanence or Ash Blossom for the opponent's first interaction (Inferred from text; no recorded boards)
• Turn 2 (going second): Use Droll & Lock Bird, Effect Veiler, Maxx C and Ash Blossom to slow the opponent's draw and summons, then resolve a Synchro from the Extra Deck (Inferred)
• Recovery: Recursion through Centur-Ion Phalanx (GY banish to Special Summon a Centur-Ion Synchro), Wake Up Centur-Ion!, Primera Primus search and Emblema Oath placement (Inferred from card text)
• After siding: Not assessable: the deck has no Side Deck, so there is no post-side plan at all

Why it scores here

The deck is Illegal in OCG: it runs one copy of Baronne de Fleur, which is Forbidden, so under the rubric it gets a capped, structural-only score rather than a normal Final Contextual score. Its structural read is about 48: Centur-Ion Primera and Stand Up Centur-Ion! give roughly a one-in-three chance of a starter in the opening five (Inferred), the archetype-core group is well represented, and the 9 hand traps plus 11 negation-text cards provide real interaction density (Inferred from text). Conversion and median output cannot be measured because the export has no recorded boards, so D3 and D4 rest on text-only inference and are scored conservatively. The deck has no Side Deck, which pulls D12 down hard, and 14 of the 23 distinct Main Deck cards are off the exact archetype name, so its engine coherence is only moderate. The score was not raised by Centur-Ion's popularity (the core-card inclusion stats only confirm the list is real) and no card scores were averaged into the deck result.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary; structural value is identical under the Balanced profile (about 48). Structural ≈ 48, Going First ≈ 45, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); weak_post_side_plan (-3). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + Modifiers = 0.80*48 + 0.20*35 - 11 = 34.4, then ILLEGAL CAP applied (deck is Illegal: Forbidden card in Main/Extra) -> final 25. Theoretical/structural-only evaluation.

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

• Archetype-core group is well represented (22 copies, 98.7% chance of at least one in opening hand, Inferred)
• Dense interaction suite: 9 hand traps and 11 negation-text cards (Inferred from text)
• Extra Deck carries multiple strong Centur-Ion Synchro bodies (Auxila, Legatia, Primera Primus)

Weaknesses

• Illegal: Baronne de Fleur is Forbidden and over the copy limit
• No Side Deck, so no best-of-3 adaptation
• Only 34.5% exact-name archetype purity; engine split across Elfnote, generic and Synchro cards
• No recorded boards, so the combo floor and ceiling cannot be measured

Critical choke points

• Baronne de Fleur (Forbidden) in the Extra Deck makes the list illegal until it is removed
• Centur-Ion Primera (3 copies, 0.338 per opening hand) is the main starter access point
• Five Limited cards (Droll & Lock Bird, Elfnote Lucina, Elfnote Tinia, Maxx C, S:P Little Knight), each at 1 copy

Recommended changes

Evidence & confidence

• Verified: Legality: Baronne de Fleur is Forbidden with 1 copy run (illegal); Deck counts: 40 Main, 15 Extra, 0 Side; within OCG size rules; Copy limits: Ash Blossom 2 copies (Semi-Limited) legal; five other Limited cards at 1 copy legal; Archetype composition: 19 exact-name Centur-Ion copies, 34.5% purity; Usage stats: Centur-Ion Legatia 66.7% inclusion and absent from this list
• Inferred: Starter access probabilities from hypergeometric draw tables (Primera 0.338; searcher group 0.78; hand-trap group 0.81); Interaction density from card text (9 hand traps, 11 negation-text cards); Going-first and going-second plans and recovery routes from card text; Consistency and brick-rate estimates
• Provisional: Meta Power: no dated metagame sample; D13 matchup and format fit: no tournament data
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record absent No win-rate telemetry in YGOVN: going-first/second, matchup and brick rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied Side Deck is empty; post-side performance cannot be assessed
