Melffy Deck #393789 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 68/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: none
• Format: master-duel

Legality

Main 41 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Combo via Spright Starter and Melffy engine to assemble board and finish with high-impact Xyz/Synchro or boss monsters; Value-based attrition and incremental card advantage through Spright draws and Melffy effects
• Turn 1 (going first): T1: Spright Starter + key hand-traps/removal; develop combo pieces by T2 and assemble for turn-3-4 finish
• Turn 2 (going second): T1: Ash Blossom + hand-trap disruption; T2: establish Spright board and answer back-row while progressing toward combo
• Recovery: Return-to-hand recursion (Melffy Pinny, Merry Melffys) and Spright re-summon paths to rebuild after disruption
• After siding: Side into targeted floodgates and removal; keep Spright Starter and hand-traps to preserve T1 plan

Why it scores here

The deck reliably opens a combo plan by T1–T2 thanks to Spright Starter and strong archetype consistency, producing high ceiling value through Xyz/Synchro finishes (D3). Its floor is constrained by brick risk and limited disruption, keeping median output moderate (D4). Disruption exists via hand-traps and targeted removal but is uneven, and the deck depends on key cards that can be answered (D5, D7). Resource flow is healthy through card draw and returns, though side adaptability and format fit are provisional without a dated meta sample (D6, D12–D13).

Dimension scores

How the score was computed

Strategy profile: Balanced (default). Structural ≈ 68, Going First ≈ 70, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: brick rate (-5); extra_deck_single_point_of_failure (-3); hand_trap_consistency (4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Strong combo ceiling with high-impact Xyz/Synchro targets
• Consistent archetype core presence and draw engine
• Effective hand-trap disruption suite
• Good resource return and grind potential

Weaknesses

• Medium brick risk from 3-card draw and Beast dependency
• Limited disruption beyond hand-traps
• Moderate pilot complexity (~8–10 decision points)
• Extra-deck answers and single-point dependencies

Critical choke points

• Timely access to Spright Starter and enablers
• Surviving back-row disruption before combo assembly
• Consistent draw to maintain value and answers

• Inferred: hand consistency and brick probabilities; combo ceiling and floor estimates; resource economy and disruption reach
• Provisional: meta share and format fit; post-side adaptability
• Data gaps: no parsed combo boards for median/ceiling numbers no win-rate or matchup telemetry no tournament or meta-share link side deck content absent
