Centur-Ion Deck #772913 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 39/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro boss pressure from the Centur-Ion Extra Deck (Centur-Ion Legatia, Centur-Ion Auxila, Centur-Ion Primera Primus) and the Dragon/Synchro bosses, after Centur-Ion Primera and Stand Up Centur-Ion! set up the field (Inferred from card text).; Hand-trap-supported Synchro lines through Crimson Dragon, Enigmaster Packbit and Red Supernova Dragon (Inferred; no recorded boards).
• Turn 1 (going first): Open with Centur-Ion Primera, Stand Up Centur-Ion! or Emblema Oath to place a Centur-Ion Continuous Trap, then Synchro Summon from the Extra Deck (Inferred).
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Ghost Ogre & Snow Rabbit, Droll & Lock Bird or Nibiru to interact with the opponent's first summon, then rebuild through the Centur-Ion searchers (Inferred).
• Recovery: Recover through the Centur-Ion searchers and the GY-to-Trap-Zone recursion of Emblema and Centur-Ion monsters (Inferred from card text).
• After siding: Not evaluable: the deck runs 0 Side Deck cards, so there is no post-side plan.

Why it scores here

This deck is scored on its structure only, because the list is Illegal: Ash Blossom & Joyous Spring is run 3 copies against an OCG limit of 2, and The Bystial Lubellion is run 3 copies against a limit of 1. The Centur-Ion core is consistent, with the archetype core present in about 99.8% of opening hands (Inferred), and 13 hand traps plus 6 negation and 9 removal effects give it real interaction on the system level. Its Synchro bosses (Legatia, Auxila, Red Supernova Dragon, Cosmic Blazar Dragon) give it closing power if the engine goes live. The score does not come from Centur-Ion being a popular archetype and does not come from averaging card scores. Median output, matchup fit and side-deck adaptability are unknown or absent (no combos, no tournament link, no side deck), which pulls confidence down to Low.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53, Going First ≈ 50, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal copy-limit violations (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional), then Illegal cap modifier -12; theoretical/structural-only

Probability & combo summary

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

Strengths

• Archetype core is almost always present in opening hands (Inferred)
• Layered interaction: 13 hand traps plus negate and removal texts
• High-ATK Synchro bosses in the Extra Deck

Weaknesses

• Illegal copy counts for two cards
• Only 36% of main-deck copies are exact Centur-Ion names; engine coherence is split across Bystial, Mulcharmy and Chaos
• No side deck
• No recorded boards, so the combo floor and median are unknown

Critical choke points

• Centur-Ion Primera and the Stand Up / Emblema placement lines, which feed the Synchro Summons
• Single-copy Centur-Ion Bonds, Bystial Druiswurm and Bystial Magnamhut (about 12.5% in the opener)

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0 counts are legal for OCG; Ash Blossom & Joyous Spring runs 3 copies vs OCG limit 2; The Bystial Lubellion runs 3 copies vs OCG limit 1; Card stats and text excerpts from evidence; Archetype purity 36.4%
• Inferred: P(>=1 core starter in opener) ≈ 0.998; Hand-trap P(>=1 in 6) ≈ 0.92; Strategy classification as Midrange with Stun and Toolbox secondaries; Going-first and going-second power estimates
• Provisional: Meta Power (null); Tournament reliability and matchup fit (no dated sample)
• Data gaps: Deck is Illegal (copy-limit violations), so the score is theoretical/structural-only No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match record absent No win-rate telemetry; going-first and going-second splits are inferred Meta Power is Provisional without a dated metagame sample No guides for the archetype (guides_evidence total 0)
