Endymion Deck #774254 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Regulus-led Endymion engine plus Magistus and Fairy Tail Extra Deck bosses (Verre Maid, Zoroa the Magistus Verethragna, Aiwass) converting ATK pressure (Inferred from card text); Fairy Tail fusion and Xyz lines (Teller, Weaver, Wiccat) with Fairy Tail Ball and Tails recursion (Inferred)
• Turn 1 (going first): Search with Fairy Tail Ball, Regulus and Spenta, then bridge into Endymion or Magistus Extra Deck monsters while holding Ash Blossom and Infinite Impermanence (Inferred)
• Turn 2 (going second): Use the 13 hand traps (Ash, Infinite Impermanence, Ghost Ogre, Droll, Effect Veiler, Maxx C) to stop the opponent's first summon or search, then rebuild from the Deck (Inferred)
• Recovery: Recur monsters through Fairy Tail Ball, Tails of the Fairy Tails and Spenta GY/banish effects, and draw back through Maxx C and Mulcharmy (Inferred)
• After siding: Not applicable: the Master Duel format has no Side Deck in this evidence (Side Deck size 0)

Why it scores here

The deck is scored as a system: 17 searcher-text cards give a 0.95 chance of at least one search in the opening five, and the Endymion starter (3 Regulus) has only a 0.34 chance of appearing in opening five, so engine accessibility is moderate rather than high. Thirteen hand traps and 16 negation-text cards give strong interaction on the end board and going second (92% chance of a hand trap in six cards), which is the deck's main source of resilience. The Extra Deck offers three archetype lines (Magistus, Fairy Tail, Endymion) with real recursion, which keeps the deck from ending on one interruption, but it is also split across three engines (exact-name purity 12.7%), which holds back conversion and consistency. No combo boards were recorded, so the ceiling and median are text-based inference and were not averaged from card scores; the Endymion archetype's popularity and the usage-statistics gap did not earn points.

Dimension scores

How the score was computed

Strategy profile: Midrange, with D13 dropped and re-normalised over 95. Structural ≈ 62, Going First ≈ 65, Going Second ≈ 67, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist exposure (-2); engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Structural renormalised without D13)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Thirteen hand traps and 16 negation-text cards give strong interaction, especially going second
• Heavy search density (17 searcher-text cards) and recursion keep resources flowing
• Three Extra Deck lines give several independent routes after disruption

Weaknesses

• Three archetype engines in 40 cards dilute starter density (exact-name purity 12.7%)
• Only 3 Regulus and 1 Endymion Empire as engine pieces; the Endymion starter is seen in opening 5 about one time in three
• No combo boards recorded, so conversion cannot be verified

Critical choke points

• Regulus (3 copies) as the Endymion starter with Endymion Empire (1 copy) as the only Endymion spell
• Single-copy Limited cards (Maxx C, Instant Fusion, Fairy Tail - Snow, Crossout Designator) have no reserve copies

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel: 40 main, 15 extra, 0 side; no size or copy-limit violations; Five Limited/Semi-Limited cards each run at their legal copy count; Archetype purity 12.7% and archetype spread as listed in composition
• Observed: Usage statistics available (22 rows), though this deck contains only 1 of 21 core cards
• Inferred: Starter probabilities and draw-based consistency estimates; Interaction and resilience scores from card text; Going-first and going-second estimates
• Provisional: Meta Power (null); D13 matchup and format fit (excluded from Structural); D12 side-deck score (neutral placeholder; no side deck in this format)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown deck title is null the guide describes Endymion as a Pendulum archetype, but no Pendulum-frame card appears in this list; the guide is used as general context only Meta Power is provisional without a dated metagame sample
