Melffy Wally — Power Evaluation

Final Score: 68 ± 6 · Confidence: Medium

  • Intrinsic: 64.3 · Deck: 70.3 · Meta: provisional
  • Primary role: Starter / Combo enabler · Secondary: Hand trap

Why it scores here

Melffy Wally scores on its ability to turn one card into two Melffy bodies: its first effect returns it to hand and Special Summons two differently named Melffy monsters from the Deck, and its End Phase effect re-summons it from hand, so the card keeps reappearing. It appears in all 400 sampled decks at about 2.1 copies each, almost always alongside Melffy Puppy and Melffy Pinny (98% co-occurrence), which confirms it is a core engine piece of the Melffy archetype rather than a generic staple. Its 0 ATK and 400 DEF count for nothing; the score rests on access, conversion and cheap deck cost, and it does not negate anything, so interaction is low. Confidence is capped at Medium because no combo boards were supplied, so conversion rests on text and deck co-occurrence.

Axis scores

Axis Score Evidence
Accessibility 80 Can be Special Summoned from hand in the End Phase and is run 2–3 copies in most decks, so it is reliably live (verified: card text; observed: decks_evidence).
Combo & Conversion 74 Returns itself and summons two Melffy monsters from the Deck, a net body gain from one card (verified: card text); no combo boards supplied, so the rest is inferred.
Resource Economy 70 Converts one card into two bodies via a self-return, a net-positive card count, with a repeatable End Phase re-summon (verified: card text; inferred for the card-advantage net).
Effect & Interaction 35 No negation or removal; the effect only responds to opponent summons or attacks by saving itself and building the board (verified: card text).
Material Utility 40 Level 2 Earth Beast body with no material evidence supplied; usable as a generic Level 2 material but awkward given its 0 ATK (inferred).
Resilience & Flexibility 60 The return-to-hand effect dodges destruction, and the End Phase summon keeps it in play across turns; a negation of its effect still leaves a 0/400 body (inferred: card text).
Deck-Building Efficiency 75 Typically 2–3 copies with no garnet or lock restriction; the 'except Melffy Wally' clause only limits its own summon targets (observed: copies_per_deck; verified: card text).

Calculation

Weight profile: 0.7 Starter / Combo enabler + 0.3 Hand trap. Intrinsic ≈ 64.3, Deck ≈ 70.3, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Converts one card into two Melffy bodies via a self-return
  • Repeatable re-summon from hand in the End Phase
  • Core engine piece: present in all 400 sampled decks at about 2.1 copies each
  • Cheap to run: no garnet or lock, copies are redundant across turns

Weaknesses

  • 0 ATK / 400 DEF; no board or damage presence on its own
  • No negation or removal, so little opponent interaction
  • Its value depends on Melffy support (high archetype dependence)
  • No combo boards supplied, so conversion is text-based

Counters / choke points

  • Negating its effect stops the return and the two-monster summon (inferred from card text; no interaction evidence supplied)

Best use

Starter / Combo enabler (Extender) with hand-trap-style summon response. Decks: Melffy. Suggested copies: 3.

Evidence & gaps

  • Verified: Card text: returns to hand, then Special Summons 2 differently named 'Melffy' monsters from the Deck (except 'Melffy Wally'); Card text: End Phase Special Summon from hand; each effect once per turn; Decks: present in 400/400 sampled decks, 2.12 average copies
  • Observed: Top partners co-occur in 95–98% of decks, indicating archetype-core usage; Usage statistics: 100% inclusion in Mystical Beast of the Forest lines and 77% in the Melffy gameplay-7 line
  • Inferred: Net card advantage of +1 from the self-return plus two summons; Usable as a generic Level 2 material despite no material evidence; Negating the effect would leave a 0/400 body
  • Data gaps: no combos supplied — combo conversion is text-only inference no banlist token — assumed 3 copies (unlimited) no material or searcher evidence supplied single guide mention; no metagame or tournament evidence
