Equip only to a "Koa'ki Meiru" monster. If it battles a LIGHT or DARK monster, destroy that monster without applying damage calculation. When the equipped monster is removed from the field and this card is sent to the Graveyard, you can return this card to your hand.
Core Blaster — Power Evaluation
Final Score: 54 ± 8 · Confidence: Medium
- Intrinsic: 52.5 · Deck: 54.5 · Meta: provisional
- Primary role: Board breaker · Secondary: Recovery/Recursion
Why it scores here
Core Blaster is a conditional battle-removal equip: it only converts when attached to a Koa'ki Meiru monster that battles a LIGHT or DARK monster, and it then returns to hand from the Graveyard, so its value is a repeatable, reusable battle answer rather than board presence. The score is held down by the archetype lock (2 distinct archetypes, 5 of 6 decks in Koa'ki Meiru) and by the absence of combo evidence to confirm it converts into a board. High ATK-independent reach is not present in the text, and nothing about the card's popularity or deck count was allowed to lift the score beyond what the 6-deck sample supports.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | Needs a live Koa'ki Meiru monster to equip to, and 5 of 6 decks run it alongside Diamond Core and Powerhand, but no searcher or starter stats exist (observed deck presence, inferred route). |
| Combo & Conversion | 30 | No recorded boards (total combos 0), so the only conversion is the text's battle-destruction effect against LIGHT/DARK monsters (inferred from text). |
| Resource Economy | 60 | Returning to hand from the Graveyard gives a repeatable recycle of the same card, a 1-for-1 reuse rather than a true card-advantage engine (verified from text, inferred scoring). |
| Effect & Interaction | 60 | Destroys a LIGHT or DARK monster in battle with no damage calculation, a strong but attribute-gated answer (verified from text). |
| Material Utility | 5 | A Spell Card with no material role; it is not usable as material at all (verified from card type). |
| Resilience & Flexibility | 55 | Recurs to hand once the equipped monster leaves and the card hits the Graveyard, but it still dies with its host to any removal before it can be used (verified from text, inferred). |
| Deck-Building Efficiency | 75 | Clean one-to-three copy spell with no garnet, lock, or self-restriction; average 1.83 copies per deck and it sits in archetype decks without locking the build (observed deck stats). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Recovery/Recursion. Intrinsic ≈ 52.5, Deck ≈ 54.5, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Clean battle-removal answer against LIGHT and DARK monsters without damage calculation
- Returns to hand from the Graveyard, so one card can be reused
- Cheap to run: 1 to 3 copies, no garnet or lock
Weaknesses
- Conditional on attribute: no value against non-LIGHT/DARK monsters
- Dies with its equipped host, so it needs a Koa'ki Meiru monster on the field
- Archetype-locked: low generic portability across homes
Counters / choke points
- Removal of the equipped monster before battle (inferred from text)
- Attribute mismatch: opponent monsters that are neither LIGHT nor DARK (inferred from text)
Best use
Battle-removal equip with Graveyard recursion. Decks: Koa'ki Meiru. Suggested copies: 2.
Evidence & gaps
- Verified: Equip Spell restricted to Koa'ki Meiru monsters, battle-destruction vs LIGHT/DARK with no damage calculation, Graveyard-to-hand recursion (card text); 6 decks run it, 5 in Koa'ki Meiru (83.3%), average 1.83 copies, max 3 (deck data)
- Observed: Co-appears with Diamond Core, Ahrima and Lair of Darkness in 5 of 6 decks (83.3%)
- Inferred: Battle-destruction is a reliable answer only when the attacker or defender is LIGHT or DARK; Recursion gives a repeatable reuse rather than card advantage; No searcher or starter route is evidenced, so accessibility rests on the archetype's monster base
- Data gaps: no combos supplied: combo conversion is text-only inference no guides supplied no usage statistics (StatisticsCard): archetype inclusion % inferred from deck sample only no banlist token: assumed 3 copies (unlimited)
