Why it scores here
Core Transport Unit is a once-per-turn discard-to-search Continuous Spell, so its score rests on reliable access to one named Iron Core of Koa'ki Meiru rather than on board presence or card advantage. Its net-zero resource line, lack of any interaction text, and non-material Spell body keep the weighted axis near 43. The strong deck fit (16 of 16 sampled decks, 100% co-occurrence with its target) lifts the deck layer, but the view count of 2891 and the card's ATK/DEF-free text earned no points, and the absence of combo boards means conversion is text-only.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Runs in 16 of 16 sampled decks at an average of 2.44 copies, but it needs a card in hand to discard and no starter or searched stats exist (observed). |
| Combo & Conversion | 35 | Turns one discarded card into one named Iron Core per turn with no board-building text; no combo boards were recorded, so this rests on card text alone (inferred). |
| Resource Economy | 50 | Discard 1 to add 1 is a net-zero exchange that upgrades a dead card into a chosen one, with no draw or extra refuel (verified). |
| Effect & Interaction | 5 | The card text contains no negation, removal, or hand-trap effect (verified). |
| Material Utility | 5 | It is a Spell Card, so it cannot be used as material and provides no body (verified). |
| Resilience & Flexibility | 45 | It must survive on the field to repeat its once-per-turn search and has no protection text, though three copies across several archetypes add some redundancy (inferred). |
| Deck-Building Efficiency | 55 | It costs about 2.4 slots per deck with no garnet or lock, but its archetype-specific wording limits where it can be used (observed). |
Calculation
Weight profile: Searcher/Tutor only; no secondary blend. Intrinsic ≈ 47.4, Deck ≈ 54.4, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Live in all 16 sampled decks, with a 100% co-occurrence rate with its target Iron Core of Koa'ki Meiru
- Once-per-turn search converts a dead card into a specific named card with no extra cost beyond the discard
- Clean, low-slot card with no garnet or lock restriction
Weaknesses
- Net-zero card economy with no draw, refuel, or board presence
- No opponent interaction and no material value
- Repeatable only while it stays on the field and no protection text exists
- Power depends on the discard fuel and the Koa'ki Meiru target being present
Counters / choke points
- Spell removal or Spell-destruction effects that stop the once-per-turn search from repeating
- Hand disruption that removes the discard fodder

Evidence & gaps
- Verified: Once-per-turn discard 1 to add 1 Iron Core of Koa'ki Meiru from Deck to hand (card text); Continuous Spell with no interaction text (card type and text); Spell Card, not usable as material (card type)
- Observed: Present in 16 of 16 sampled decks, average 2.44 copies, 3 copies in 11 decks (deck evidence); 100% co-occurrence with Iron Core of Koa'ki Meiru and Koa'ki Meiru Urnight (deck partner evidence); Spread across 8 archetypes (deck evidence)
- Inferred: Discard-cost access makes it a practical searcher in the Koa'ki Meiru shell (text plus deck evidence); Resilience is limited by reliance on the field presence to repeat the search (text-based inference)
- Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, so 3 copies (unlimited) is assumed no usage statistics (StatisticsCard), so archetype inclusion % is inferred from the deck sample only the Iron Core of Koa'ki Meiru target's own text is not in evidence the archetype name 'Koa'ki Meiru' appears under three archetype IDs (1341, 1072, 1239), treated as one home
