Why it scores here

Combination Attack is a Battle Phase Quick-Play that only works on a monster that has already attacked this turn and is equipped with a Union Monster. Its real value is one extra attack for a Union-based board, which is a narrow conversion with no searching, drawing, or interaction. The four sampled decks confirm it is a live tech in Union-oriented lists, but no combo boards were recorded, so the score rests on the card text and deck placement. High ATK and the card's popularity do not factor in.

Axis scores

Axis Score Evidence
Accessibility 35 Live in 4 sampled decks at 1 copy each across 2 archetypes, but it is not searchable and needs a Union monster already on the field that has attacked (deck evidence, inferred route).
Combo & Conversion 30 No recorded combo boards, so conversion is text-only: one extra attack for an existing Union setup (inferred).
Resource Economy 30 Spends a card for a re-attack and draws or recovers nothing, so it is roughly a 1-for-1 at best (inferred from text).
Effect & Interaction 5 No negation, removal, or disruption of any kind (verified from card text).
Material Utility 5 A Spell has no material body value; the effect only changes a Union monster's equip state (verified from card text).
Resilience & Flexibility 25 Quick-Play is hard to stop with a single response, but its single narrow use and reliance on Union setup leave little redundancy (inferred).
Deck-Building Efficiency 65 Single-copy slot with no garnet or lock restriction, but only worth running in Union decks (observed in 4 decks, copies 1 each).

Calculation

Weight profile: Primary role Extender; no secondary weighting applied because secondary roles are minor. Intrinsic ≈ 35, Deck ≈ 34, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Weaknesses

Counters / choke points

  • Any response that negates or stops the attacking Union monster before Battle Phase resolution would stop the re-attack (inferred from text)

Evidence & gaps

  • Verified: Battle Phase Quick-Play that targets a monster which attacked this turn and is equipped with a Union Monster; Effect returns the Union Monster to face-up Attack or Defense Position and lets the equipped monster attack again; Appears in 4 sampled decks at 1 copy each
  • Observed: Partner cards in the sampled decks are Union and ABC support cards; Two archetype homes in the sample (ABC and no archetype)
  • Inferred: Reliable use depends on having an attacking Union monster already on the field; Conversion is one extra attack, not a board-building effect
  • Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no usage statistics (StatisticsCard) for inclusion % by archetype no banlist token, assumed 3 copies (unlimited)
