Why it scores here

Core Overclock is a Continuous Spell that gives a static +500 ATK to face-up Koa'ki Meiru monsters, with an optional once-per-turn discard of an Iron Core of Koa'ki Meiru for a further +1000 ATK until the End Phase. It converts nothing into board presence, cards or interaction by itself, and its only real value is ATK pressure inside a single archetype. The 1500 combined ATK bonus earns almost no points: the rubric rewards conversion, resource gain and interaction, and this card offers little of each. Its score rests mainly on being run in 9 of 9 sampled decks, which confirms accessibility and archetype fit rather than power.

Axis scores

Axis Score Evidence
Accessibility 45 It is in all 9 sampled decks at about 1.2 copies each, but there are no combo starter or searched records, so live-hand access is only inferred (observed).
Combo & Conversion 20 The card has zero recorded combo appearances and its text only buffs ATK, so conversion into a board is text-only inference (inferred).
Resource Economy 25 The optional boost costs a discard of an Iron Core, a net -1 card with no return, and the static buff costs nothing (verified).
Effect & Interaction 5 The card has no negation, removal or hand-trap effect (verified).
Material Utility 0 It is a Spell and cannot be used as material (verified).
Resilience & Flexibility 30 It is a Continuous Spell that can be destroyed by spell and trap removal, and its ATK bonus disappears once the monsters leave the field; this is an inference from general rules, not from the evidence (inferred).
Deck-Building Efficiency 45 It is one slot at one to two copies with no garnet, but it only does anything with Koa'ki Meiru monsters, so it is a mild archetype restriction (verified).

Calculation

Weight profile: Utility default profile, no secondary role. Intrinsic ≈ 31.5, Deck ≈ 34.9, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Present in all 9 sampled decks, all Koa'ki Meiru or near-archetype
  • Static ATK buff needs no cost
  • Cheap single slot with no garnet

Weaknesses

  • No combo evidence of board creation or card advantage
  • The optional buff costs a card from hand or the field's resource pool for a net -1
  • Dead when no Koa'ki Meiru monsters are face-up
  • Its value is only ATK, which is weak against non-battle plays

Counters / choke points

  • Spell and trap removal, since it is a Continuous Spell (inferred)

Best use

ATK support for the Koa'ki Meiru monster core in a Koa'ki Meiru deck. Decks: Koa'ki Meiru. Suggested copies: 1.

Evidence & gaps

  • Verified: Card text: static +500 ATK to face-up Koa'ki Meiru monsters; once per turn discard of an Iron Core of Koa'ki Meiru for +1000 ATK until End Phase; Present in 9 of 9 sampled decks, 7 of them under the Koa'ki Meiru archetype; Iron Core of Koa'ki Meiru co-occurs in 9 of 9 decks
  • Observed: Average 1.22 copies per deck, max 2; Koa'ki Meiru Supplier and Urnight co-occur in 9 of 9 decks
  • Inferred: Continuous Spell can be destroyed by spell and trap removal; Live-hand access depends on draw and search routes not recorded in the combo evidence
  • Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, assumed 3 copies (unlimited) no usage statistics (StatisticsCard), so archetype inclusion is inferred from the deck sample only
