Why it scores here

Flash Fusion turns the monsters you already control into a single Fusion Monster from the Extra Deck, which is a real conversion, but the Fusion is destroyed in the End Phase, so it converts board presence into a temporary body rather than lasting value. It has no searcher, no recursion, and no negation, so it earns little on resource economy or interaction. The 36-deck sample (22 archetypes, 80.6% in one gameplay type) shows the card is practically accessible and cheap to run at 1-2 copies, but its partners (Ash Blossom, Maxx C, Called by the Grave) are generic staples, so that frequency confirms accessibility, not power. No combo boards are recorded, so the conversion score rests on text plus deck evidence.

Axis scores

Axis Score Evidence
Accessibility 62 Needs Fusion-material monsters already on the field plus a matching Extra Deck Fusion; no searcher is attested in the evidence, but 36 recent decks run it across 22 archetypes (observed, inferred for the field requirement).
Combo & Conversion 55 Text says it Fusion Summons one Fusion Monster from the Extra Deck, a one-card conversion into a body, though the body is destroyed in the End Phase; zero combo boards recorded, so this is inference from text.
Resource Economy 20 Spends field monsters as material and returns no card advantage or GY refuel; the destruction clause removes the Fusion body (verified from text).
Effect & Interaction 15 No negation, removal, or disruption text; it is a pure Fusion Summon (verified from text).
Material Utility 20 A spell card, so it has no body to use as material; the Fusion it produces is a temporary summon, not a material provider (verified from text).
Resilience & Flexibility 40 A single Quick-Play spell with no recovery; 14 of 36 decks run 2 copies, which gives some redundancy (observed from deck copies).
Deck-Building Efficiency 70 Spell card with no garnet or lock and no self-restriction, and 1-2 copies per deck fits cleanly (observed from copies per deck and card text).

Calculation

Weight profile: Starter / Combo enabler (0.7) blended with Extender (0.3) as secondary role. Intrinsic ≈ 50.7, Deck ≈ 53.2, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck (decks present, meta unknown; combos absent)

Strengths

  • Converts field monsters into a Fusion Monster from the Extra Deck in one card
  • Low deckbuilding cost: spell card, 1-2 copies, no garnet or lock
  • Live in 36 recent decks across 22 archetypes, so it is not a forgotten niche pick

Weaknesses

  • The Fusion is destroyed in the End Phase, so the board gain is temporary
  • No searcher, recursion, negation, or card advantage
  • Requires both field material and a matching Extra Deck Fusion

Counters / choke points

  • Generic negation or Fusion-disruption cards; the evidence names no specific counter

Best use

One-card Fusion conversion for a single turn of board pressure. Decks: Fusion-based decks such as Witchcrafter, Frog, Dark Magician, and Heroic lines (archetype presence from deck data).

Evidence & gaps

  • Verified: Card text: Fusion Summon 1 Fusion Monster from the Extra Deck using monsters you control as material; destroyed during the End Phase; Copies per deck: average 1.39, max 2, 14 of 36 decks run 2
  • Observed: Present in 36 recent decks across 22 archetypes; 80.6% in gameplay type 7; Top partners include generic staples (Ash Blossom, Maxx C, Called by the Grave)
  • Inferred: Accessibility depends on field material plus a matching Extra Deck Fusion; Combo conversion is text-based because no combo boards are recorded
  • Data gaps: no combos supplied; combo conversion is text-only inference no banlist token; assumed 3 copies (unlimited) no usage statistics (StatisticsCard); archetype inclusion % inferred from the deck sample only no guide text on how the card is actually sequenced
