Why it scores here

Joyous Melffys is a Rank 2 Beast Xyz whose real value is its opponent's-turn Quick Effect: it returns a Beast Xyz to the Extra Deck and Special Summons Level 2 or lower Beasts from the GY, up to that Xyz's material count, which converts a single Xyz into a recursion line. It is present in all 400 sampled decks, but that consistency only supports accessibility and deck fit; it adds no points on its own. Its 2000 ATK, the 92% and 78% inclusion rates in usage statistics, and the Melffy archetype's popularity earned nothing, and the once-per-turn limit and text-only combo conversion (no combo corpus) keep the score in the middle band.

Axis scores

Axis Score Evidence
Accessibility 70 Present in 400 of 400 sampled decks at 1.15 average copies and reached through Level 2 Beast Melffy monsters, but it needs a Rank 2 Xyz summon, so it is not a free opening-hand card (observed).
Combo & Conversion 55 No combo boards were supplied, so the conversion of the recursion effect into a multi-body board is text-only inference, leaving it at a moderate value (inferred).
Resource Economy 60 Detaching one material for direct attacks is a cost, but the quick effect converts a returned Xyz into up to its material count of GY summons, which is a real refuel (verified from card text).
Effect & Interaction 35 No negation or removal; the quick effect only rescues a Beast Xyz from opponent actions in the opponent's turn, once per turn (verified from card text).
Material Utility 25 As a Xyz monster it is a poor material body and is not a clean generic Level or attribute provider for other summons (inferred from card type and text).
Resilience & Flexibility 50 Once-per-turn quick effect usable in the opponent's turn gives some recovery, but it covers one Beast Xyz per turn and no multi-turn redundancy is shown (verified from card text, inferred for the rest).
Deck-Building Efficiency 70 Typically one copy in a Melffy-based deck, no garnet or lock restriction in the evidence, and a single Xyz slot that is cheap to run (observed, 1.15 average copies).

Calculation

Weight profile: 0.7 Recovery/Recursion + 0.3 Extender. Intrinsic ≈ 56, Deck ≈ 61, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Quick-speed recursion of a Beast Xyz in the opponent's turn
  • Summon-up-to-material-count from the GY refuels the board
  • Live in 400 of 400 sampled decks with strong partner synergy with the Melffy line
  • Low deck cost at one typical copy

Weaknesses

  • Once-per-turn limit on the quick effect
  • Requires a Rank 2 Xyz summon and Beast Level 2 bodies
  • Poor material utility as a Xyz monster
  • No negation or removal of its own

Counters / choke points

  • Negation of the quick effect (inferred; no rulings in evidence)
  • Removing the targeted Beast Xyz in response is only partly answered by the return (inferred)

Best use

Recursion and resilience piece for Beast Xyz lines, with direct-attack support for Melffy monsters. Decks: Melffy, Mystical Beast of the Forest, Frog. Suggested copies: 1.

Evidence & gaps

  • Verified: Quick Effect in the opponent's turn returns a Beast Xyz to the Extra Deck and summons Level 2 or lower Beasts from the GY, up to its material count, once per turn; Detaching one material allows Melffy monsters to attack directly this turn; Present in 400 of 400 sampled decks, 1.15 average copies
  • Observed: Melffy archetype 45% of decks, 43 distinct archetypes; Usage statistics show 50% to 100% inclusion across 5 archetype rows; Top partners Melffy Catty, Melffy Pinny and Melffy Puppy each appear in over 93% of decks
  • Inferred: Recursion is the primary role, with extender as secondary; Opponent-turn quick effect gives limited protection to a Beast Xyz against removal; Material utility is weak because it is a Xyz monster
  • Data gaps: no combo corpus supplied: combo conversion is text-only inference no banlist token: assumed 3 copies (unlimited) no rulings or interaction rulings in evidence usage statistics limited to 5 archetype rows top-card data not ranked (top-card status false)
