Endymion Deck #516206 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Tempo
• Format: master-duel

Legality

Main 42 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Pendulum and Link pressure: Endymion, Servant of Endymion and Reflection of Endymion build Spell Counters and destroy the field, then Link Summoned boss monsters (Selene, Crusadia Avramax, Underworld Goddess) attack through the emptied board.; Synchro-free Link beatdown from Amblowhale and Promethean Princess once the Pendulum Zone is established.
• Turn 1 (going first): Opening hand needs a Pendulum pair plus a searcher: Spell Power Mastery fetches Endymion, the Spell Counter engine starts, and Upstart Goblin or Pot of Desires supplies extra draws. Its T1 plan depends on hitting one of the 16 archetype-core cards (about 92% at least one in a 5-card hand, Inferred).
• Turn 2 (going second): Hand-trap-free, so going second relies on Called by the Grave (illegal here) and Triple Tactics Talent or Linkuriboh-style answers; the deck has no legal hand traps and only a 6-card-hand plan of Pendulum summons.
• Recovery: Spell Counter removal effects and Mythical Institution recover Spell Counters and search Pendulum monsters from the Extra Deck after a board wipe; Reflection and Servant can re-Special Summon once counters are placed.
• After siding: No Side Deck is registered (0 of 15 slots used), so there is no post-side plan in the evidence; the deck cannot adapt between games as submitted.

Why it scores here

The score reflects the deck as a system: a Pendulum engine (Endymion, Servant, Reflection, Astrograph) that a 16-card archetype-core group (about 92% at least one in a 5-card hand, Inferred) can start, converting into 15 Link monsters with high ATK and an end-board that Spell Counter removal can clear. Consistency is capped by the single-copy odds of any one starter (about 32% per copy in a 5-card hand) and by 23 spells, several of which (Chicken Game, Into the Void, Pot of Desires) are not engine pieces. No combo boards were recorded, so the ceiling and floor are text-only inference, and the score is low-confidence. The deck is Illegal in Master Duel (2 Forbidden Called by the Grave, 3 Allure of Darkness against a limit of 1), so it is capped at 35 and treated as theoretical/structural only. Popularity and usage share did not earn points, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 53.5, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8). Final formula: Illegal cap: raw 0.80*53.5 + 0.20*45 - 8 (banlist exposure) = 43.8, capped to 35 (theoretical/structural only; Meta Provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• Engine density: 16 searcher-text cards and 16 archetype-core copies give a high chance of at least one starter
• Link ceiling: 15 Link monsters with 3000-ATK options

Weaknesses

• Illegal list: Called by the Grave (Forbidden) and Allure of Darkness (over limit) must be removed
• No Side Deck (0 of 15), so no post-side plan
• Low single-copy starter odds (~32% per Endymion copy in hand)

Critical choke points

• Pendulum scale pair must be legal and open before the Endymion engine starts
• Link materials must be on the field for any Link Summon, so one board wipe stalls the Extra Deck

Recommended changes

Evidence & confidence

• Verified: Main 42 / Extra 15 / Side 0 counts within Master Duel size rules; Called by the Grave Forbidden, 2 copies run; Allure of Darkness Limited, 3 copies run, limit 1; Card stats and text for all 35 distinct cards; Archetype core group 16 copies
• Inferred: Hypergeometric starter odds (0.92 group, 0.32 per copy); Going-first and going-second plans from card text; Combo ceiling and floor from text only; Interaction density from negation and removal text
• Provisional: Meta Power and format fit (no dated metagame); Tournament reliability
• 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 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 No Side Deck supplied (0 cards), so D12 is Inferred/Provisional Banlist status of the recommended replacement cards is not in the evidence; legality must be confirmed
