Melffy — Deck Power Evaluation
Final Contextual Deck Power: 25/100 (±5 · Confidence: Low)
| Overall score | Value |
|---|---|
| Structural Deck Power | 59 |
| Going First | 65 |
| Going Second | 60 |
| Meta Power | provisional |
| Tournament Reliability | 40 |
- Primary strategy: Combo
- Secondary strategies: Control
- Format: ocg
Legality
Main 55 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).
Identity & game plan
- Win condition: Melffy board with XYZ/Synchro and layered hand traps; Disruptive non-engine shutdown
- Turn 1 (going first): Search Melffy combo via Footsteps/Rabbys, establish interaction
- Turn 2 (going second): Board break with Lightning Storm/Evenly then beat down
- Recovery: Recursion via Footsteps GY, Tag, Hide-and-Seek
- After siding: No side deck present
Why it scores here
This Melffy list is evaluated as an illegal deck because its Extra Deck contains 16 cards against the OCG limit of 15, so the Final Contextual Deck Power is capped low per rubric. The system itself shows a modest combo engine with core Melffy searchers (Footsteps, Rabbys) and a heavy non-engine interaction suite (Ash, Impermanence, Dominus Purge, Lightning Storm), but it omits several archetype-standard extra-deck pieces (Mommy, Godmommy, Joyful Surprise, Rescue Cat) and runs 55 main cards, reducing consistency and ceiling. No recorded combos were supplied, so floor/ceiling are inferred from card text only, not from averaging individual card scores. Popularity of Melffy did not earn points; the score reflects system coherence and illegality penalty.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 65 | P(open archetype core ≥1 in 5) ≈ 0.81 from 15-copy group; missing Rescue Cat lowers real accessibility (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 60 | 55-card main with 3 unresolved cards and 1 normal garnet Rabby; hand-trap density high but extra size illegal (Inferred) |
| D3 | Combo Conversion & Ceiling | 60 | No parsed boards; text suggests Fusion/Synchro lines via Rabbys/Playtime but missing extra pieces caps ceiling (Inferred) |
| D4 | Combo Floor & Median Output | 50 | Median output likely hand traps + small Melffy board due to 46.7% core present; no combo data (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Some recursion (Footsteps GY, Tag) but single choke on Extra size and missing Mommy reduces route redundancy (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Hide-and-Seek and Footsteps provide card recycle; resource signature modest (Inferred) |
| D7 | End-Board & Interaction Quality | 75 | Interaction density high: 13 hand traps, Dominus Purge, Impermanence, Evenly (Observed flags) |
| D8 | Going-Second & Board-Breaking Power | 70 | Lightning Storm, Evenly Matched, Book of Eclipse give going-second break power (Verified text) |
| D9 | Offensive Pressure & Closing Power | 45 | Beatsticks weak (max ATK 3000 Zeus but not archetype); low offensive pressure (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 60 | 55 main exceeds typical 40-45, off-archetype purity 39.4%, some garnet (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 55 | Extra 16 illegal; contains 7 XYZ, 6 Synchro, 2 Fusion, 1 Link but missing core Melffy extra (Verified count) |
| D12 | Side Deck Adaptability | 10 | Side deck 0 cards; no post-side adaptability in best-of-3 (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No dated metagame sample; matchup fit provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 60 | Combo steps require synchro/xyz knowledge; missing core raises misplay risk (Inferred) |
How the score was computed
Strategy profile: 0.8 Combo + 0.2 Control. Structural ≈ 59, Going First ≈ 65, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal extra deck size (-34). Final formula: Illegal deck: structural theoretical only, final capped low (no normal formula)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.81 · key two-card combo ≈ — · full-brick estimate ≈ 0.19 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Heavy interaction suite
- Decent Melffy searchers (Footsteps, Rabbys)
Weaknesses
- Illegal extra deck size
- Missing core extra-deck Melffy pieces
- 55-card main dilutes consistency
Critical choke points
- Extra deck over limit
- Lack of Rescue Cat
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 1 extra-deck card to meet 15 limit | Legality | |
| 2 | 3 unresolved cards | Rescue Cat | Core consistency |
Evidence & confidence
- Verified: Legality extra size; Card text for hand traps; Extra deck count 16
- Observed: Role tag counts from composition
- Inferred: Consistency probabilities; Combo ceiling from text; Brick estimate
- Provisional: Meta Power without dated sample
- Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent 1 passcode(s) in CardIDList could not be resolved to a card (counted as main) no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
