Koa'ki Meiru Deck #106961 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Synchro boards built from Adamancipator / Koa'ki Meiru / Superheavy Samurai tuners, closed by 3000-ATK Synchros (Adamancipator Risen - Dragite, Crystal Wing Synchro Dragon, Baronne de Fleur if legal); Hand-trap-supported grind: Ash Blossom, Droll & Lock Bird and Nibiru stall the opponent while the Synchro board develops
• Turn 1 (going first): Open Analyzer / Seeker / Researcher tuner bootstraps, excavate into a Level 4 or lower Rock, then Synchro Summon a 3000-ATK boss; hold Ash or Droll for the opponent's first search
• Turn 2 (going second): Hold 6 cards with at least one of 9 hand traps (P>=1 about 0.68); negate the opponent's starter and then rebuild through the Synchro line
• Recovery: Adamancipator Researcher / Seeker re-summon from hand after GY sends; Koa'ki Meiru Supplier recovers Iron Core; Gameciel and Dinowrestler Pankratops as board breakers
• After siding: No side deck is registered, so there is no post-side plan; a best-of-3 event would need the 15 side slots filled first

Why it scores here

The deck opens a Synchro engine reliably enough on paper: three-copy tuners (Analyzer, Seeker, Researcher) can each bootstrap from hand, and the archetype-core proxy gives P(at least one core card in a 5-card hand) of about 0.95 (Inferred). Its strongest score is end-board interaction (D7 70), because nine hand traps, ten negation texts and eighteen removal texts give layered answers to the opponent's starters and boards. Recorded combos are absent, so the floor, median and ceiling are text-only inferences and were scored conservatively (D3 48, D4 40); no average of card scores was used. Usage popularity confirms the Koa'ki Meiru and Adamancipator builds are real, but the list runs only 6 exact-name Koa'ki cards (8.6% purity) across 17 sub-archetypes, which weakens engine coherence. The deck is Illegal: two Forbidden cards and four over-limit copies, plus no side deck, so the structural score (about 51) is theoretical only and the final score is capped at 30.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Toolbox noted as secondary, weights not blended. Structural ≈ 51, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-7); no side deck (-3); engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 49.2; modifiers -12 gives 37.2; capped to 30 because the list is Illegal

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 hand-trap and negation suite (9 hand traps, 10 negation texts)
• Three-copy self-summoning tuners give redundant starters
• Synchro bosses at 2500-3000 ATK close the game

Weaknesses

• Two Forbidden cards and four over-limit copies make the list illegal
• Low archetype purity (8.6% exact name) and off-archetype spread across 17 sub-archetypes
• No side deck
• Large Extra Deck spread (14 distinct Extra cards) with no recorded combos

Critical choke points

• Opening tuner bootstrap (Analyzer, Seeker, Researcher) is required for most lines
• Koa'ki Meiru Guardian's End Phase self-destroy needs an Iron Core in hand or a Rock reveal

Recommended changes

Evidence & confidence

• Verified: Main 55 / Extra 15 / Side 0 within size rules; Forbidden status of Abyss Dweller and Baronne de Fleur; Copy-limit violations for Ash, Anti-Spell, Droll and Druiswurm; Exact-name purity 8.6%; Zero side-deck cards
• Observed: Usage stats show 8 of 25 archetype core cards present (32%)
• Inferred: Hypergeometric P(at least one starter in 5) = 0.25 per 3-copy card; Interaction density from text roles (9 hand traps, 10 negation texts); Synchro board closing power from ATK values; Engine accessibility from tuner bootstrap text
• Provisional: Matchup and format fit (D13) without a dated meta sample; Meta power (null)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record are absent No win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No side deck, so post-side performance cannot be assessed Deck title is null; archetype is taken from the export
