Melffy Catty — Power Evaluation

Final Score: 66 ± 4 · Confidence: Medium

  • Intrinsic: 64 · Deck: 64 · Meta: provisional
  • Primary role: Searcher/Tutor · Secondary: Extender

Why it scores here

Melffy Catty excels as a consistency anchor and recurring board body in Beast-focused decks, particularly Melffy and Spright, where its repeating summon-triggered search plus end-phase resummon cycle provides both deck toolbox access and cumulative board extension. The 200/200 stat line contributes nothing to the score—this card earns points on reliable activation windows, archetype synergy, and multi-archetype portability, not on raw stats. Without combo data, board depth is inferred from text mechanics and its 98.2% co-appearance with primary Melffy searchers, confirming it anchors consistency rather than burst power.

Axis scores

Axis Score Evidence
Accessibility 78 Appears in 400 decks across 53 archetypes with 98.2% co-appearance with Melffy Pinny and 94.2% with Melffy of the Forest, strongest in Melffy (33%) and Spright (16.5%) (observed)
Combo & Conversion 55 Repeating trigger cycle—opponent summon/attack returns card to hand, then searches a Beast monster, then resummons at end phase—enables deck consistency and incremental board value, but exact board depths unknown due to zero combo data (inferred)
Resource Economy 52 Return-then-add effect nets zero cards short-term; free end-phase special summons generate cumulative board and tempo value on repeated turns (inferred)
Effect & Interaction 15 Provides no direct negation, removal, or disruption; guide explicitly notes weak body as a liability (verified)
Material Utility 68 Clean Level 2 EARTH Beast typing enables synchro/xyz/link plays and strong archetype synergy; remains valid material even when effect-negated (inferred)
Resilience & Flexibility 62 Recurring cycle and hand-return mechanic avoid destruction and extend utility across multiple turns; activation tied to opponent summons or attacks, providing moderate redundancy beyond passive end-phase resummon (inferred)
Deck-Building Efficiency 77 Splashable across 53 archetypes with no self-locking effects; average 1.48 copies per deck (range 1–3) with minimal garnet risk (observed)

Calculation

Weight profile: 0.7 × Searcher/Tutor + 0.3 × Extender. Intrinsic ≈ 64, Deck ≈ 64, Meta = provisional. Modifiers: Consistency splashability (2). Final formula: 0.40×Intrinsic + 0.60×Deck

Strengths

  • Repeating activation cycle provides deck consistency and toolbox tutor access across multiple turns
  • Hand-return mechanic enables protection and multi-turn relevance without facing effect negation
  • Highly splashable in Beast-focused archetypes (53 homes, 98% co-appearance with primary searchers)
  • Clean Level 2 Beast material value; remains useful as synchro/xyz/link fodder even when effect-negated

Weaknesses

  • 200/200 ATK/DEF stats contribute zero power; card anchors deck consistency, not board presence
  • Activation depends on opponent summons or attacks; passive end-phase resummon alone provides slow extension
  • No direct disruption, negation, or removal capabilities; purely a consistency engine
  • Combo conversion measured only from text; no combo boards supplied to verify actual board progression

Counters / choke points

  • Negation of the search effect halts the tutor portion of the cycle
  • Decks that avoid summoning or attacking into Melffy Catty leave only end-phase resummon active
  • Early discard or banishment before the repeating cycle establishes limits its cumulative value

Best use

Consistency engine and toolbox tutor. Decks: Melffy, Spright, Frog, Nimble.

Evidence & gaps

  • Verified: Card text and HOPT timing complete and clear from description; Appears in 400 decks across 53 distinct archetypes per deck data; 98.2% co-appearance with Melffy Pinny (393 of 400 decks); 94.2% co-appearance with Melffy of the Forest (377 of 400 decks); No banlist token; assumed unlimited copies in TCG, OCG, and MasterDuel
  • Observed: Average 1.48 copies per deck (1 copy: 231 decks, 2 copies: 147 decks, 3 copies: 22 decks); Primary archetype homes: Melffy 33%, Spright 16.5%, Nimble 5.5%, Frog 5%; Usage statistics show 100% inclusion in Frog (both gameplays), 88.89% in Melffy gameplay 4, 69.23% in Melffy gameplay 7; Guide identifies weak body (200/200) as characteristic weakness of the archetype line
  • Inferred: Primary role Searcher/Tutor from card text effect 'add 1 Beast monster from your Deck to your hand'; Secondary role Extender from card text effect 'Special Summon this card from your hand' during end phase; Accessibility score 78 based on 98.2% co-appearance with searcher Melffy Pinny and presence in 53+ archetype homes; Combo conversion score 55 estimated from repeating cycle mechanics (bounce + search + resummon) without measured boards; Resource economy score 52 from net-zero card advantage per cycle balanced against cumulative free summons; Material utility score 68 from Level 2 EARTH Beast typing suitable for synchro, xyz, and link material; Resilience score 62 from multi-turn relevance and hand-return protection, limited by opponent-action dependency
  • Data gaps: No combo data supplied (zero combos); combo_conversion and board progression measured text-only Single guide with minimal snippet (one section); limited human narrative on archetype role depth No banlist token; assumed unlimited (verify TCG/OCG/MasterDuel if restricted) Top-card ranking absent; cannot confirm competitive representation tier across major events
