Koa'ki Meiru Deck #70464 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Combo
• Format: tcg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Magnet Warrior and Adamancipator chains that reach Berserkion the Electromagna Warrior, Adamancipator Risen - Dragite, Utopic Draco Future or Drill Driver Vespenato for a board-dominating attack; Gorgonic and Gagagaga Xyz boards that negate and attack through the opponent's monsters
• Turn 1 (going first): Normal Summon Adamancipator Seeker or Researcher, excavate for a Rock monster, and use Magnet Warrior searches and Special Summons to reach a 3000 ATK boss by the second turn
• Turn 2 (going second): Use Ash Blossom & Joyous Spring and the Koa'ki Meiru negation monsters to stop the first summon, then rebuild the Magnet Warrior chain from the Graveyard
• Recovery: Recover through the Adamancipator excavate and Magnet Warrior Graveyard revival effects, plus Gallant Granite's search or Special Summon
• After siding: No side deck is present, so no post-side plan can be evaluated

Why it scores here

The score is set by how the deck works as a system, not by averaging card scores. The Magnet Warrior and Adamancipator starters, most at three copies, give a reasonably reliable opening into a live engine by turn two (Inferred). Its Graveyard revival and excavate effects keep the engine going after a single interruption, and Ash Blossom plus the Koa'ki Meiru negation monsters provide meaningful interaction. Offensive closing power is credible because several 3000 ATK bosses are in the Extra Deck, but the median output is held down by heavy copy counts that drive brick risk. The deck is capped at 30 because four Forbidden cards in the Extra Deck make the list illegal, so this is a theoretical, structural-only read. Popularity and archetype usage are not counted toward the score.

Dimension scores

How the score was computed

Strategy profile: Midrange profile; Combo secondary noted but not blended numerically. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-10); no side deck (-2). Final formula: No reliable metagame: 0.80*Structural(55) + 0.20*TournamentReliability(45) = 53; modifiers total -12 gives 41; capped at 30 because the list is Illegal (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.8 · 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 3-copy starter package gives reliable T1 access (Inferred)
• Multiple 3000 ATK bosses in the Extra Deck give closing power (Inferred)
• Negation and hand-trap coverage from Ash Blossom and Koa'ki Meiru monsters (Inferred)

Weaknesses

• Four Forbidden cards make the list illegal
• No side deck for post-side adaptation
• Extra Deck slots spent on Forbidden and low-flexibility cards
• Heavy 3-copy starters raise brick risk (Inferred)

Critical choke points

• Forbidden Extra Deck cards removing a fixed slot of the Extra Deck
• Reliance on Alpha, Beta and Gamma to start the Magnet chain
• Koa'ki Meiru Overload and Guardian must be sent or revealed to survive each End Phase

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: four Forbidden cards in Extra Deck (legality block); Main Deck is 40 cards and Extra Deck is 15 cards, which fits the TCG size rules; Ash Blossom & Joyous Spring runs 2 copies (Semi-Limited limit 2)
• Inferred: Starter access about 0.80 in a 5-card opening; Midrange primary with Combo secondary; Brick risk moderate from 3-copy hand-dependent starters
• Provisional: Meta power and matchup fit (no dated metagame sample)
• 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 absent no win-rate telemetry exists in YGOVN - going-first/second and matchup signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck in the list
