Why it scores here
Urgent Synthesis is an archetype-locked extender that converts an Iron Core of Koa'ki Meiru already sitting in the Graveyard into a free Special Summon of a Level 4 or lower Koa'ki Meiru monster from hand or Graveyard. Its value is real but narrow: it recycles the archetype's key resource while putting a body on board, yet it offers no disruption and only functions when the Graveyard setup already exists. It appears in just 2 Koa'ki Meiru decks at 1 copy with no recorded combo usage, so the score is driven by conditional accessibility and modest combo/resource value. Its 0 ATK/DEF stats earn nothing here.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 48 | A Normal Spell, but live only when an 'Iron Core of Koa'ki Meiru' is already in the Graveyard, so it needs specific setup; it shows up in 2 decks at 1 copy (verified/observed). |
| Combo & Conversion | 45 | Special Summons only a single Level 4 or lower Koa'ki Meiru monster from hand or Graveyard — one extra body, not a full board — and no combos are recorded (verified/observed). |
| Resource Economy | 55 | It spends the Spell but returns Iron Core from Graveyard to Deck and rebuys a monster, keeping the archetype's key resource roughly even-to-positive (inferred). |
| Effect & Interaction | 8 | The card provides no negation, removal, or disruption of the opponent's plays (verified). |
| Material Utility | 50 | It delivers a clean Level 4-or-lower body usable as Xyz/Synchro material even though the Spell itself has no ATK/DEF (verified). |
| Resilience & Flexibility | 40 | It functions from both hand and Graveyard and recurs the core, but is fully dead without Iron Core in the Graveyard and folds to a single negation (inferred). |
| Deck-Building Efficiency | 42 | One slot and one copy with no self-lock, but strictly archetype-locked to Koa'ki Meiru with a required Iron Core in Graveyard, so it is not splashable (verified). |
Calculation
Weight profile: 0.7 Extender + 0.3 Recovery/Recursion. Intrinsic ≈ 45, Deck ≈ 43, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Evidence & gaps
- Verified: Card text: return 1 'Iron Core of Koa'ki Meiru' from Graveyard to Deck, then Special Summon 1 Level 4 or lower 'Koa'ki Meiru' monster from hand or Graveyard; The card provides no negation, removal, or disruption; 0 combo appearances recorded
- Observed: 2 decks run it, both main-deck, 1 copy each; 100% of decks running it also run Koa'ki Meiru Supplier, Urnight, and Diamond Core of Koa'ki Meiru
- Inferred: Requires Iron Core of Koa'ki Meiru in the Graveyard to be live, making it a conditional extender; Roughly even-to-positive on the archetype's resource loop by recycling Iron Core and rebuying a monster; Functions as a Material body out of hand or Graveyard but folds to a single negation
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only only 2 decks of deck evidence — archetype fit thin
