Endymion Deck #765386 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 49/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Endymion and Pendulum-zone counter plays that destroy the field and convert into 2800-ATK boards (Endymion, Mythical Beast Master Cerberus) backed by Link and Fusion finishers from the Extra Deck; Link and Fusion boards from the 15-card Extra Deck (Selene, Accesscode Talker, Red-Eyes Dark Dragoon, Dark Magician of Destruction) once the Main Deck has produced material
• Turn 1 (going first): Search with Spell Power Mastery or Servant of Endymion, set Spell Counters with Chicken Game and Upstart Goblin, then pendulum-summon the Endymion engine and destroy the opponent's key cards
• Turn 2 (going second): Use Droll & Lock Bird and the Endymion pendulum engine to stop the opponent's first draws and rebuild through Spell Counter removal, then convert with a Link Summon
• Recovery: Spell Power Mastery and Servant of Endymion recur the Spell Counter engine, and Mythical Institution and Soul Servant refill the hand (Inferred)
• After siding: Not evaluable: the deck runs no Side Deck, so there is no post-side plan

Why it scores here

The deck is scored as a system: a 15-searcher package (about 92% to hit at least one searcher in a 5-card opening hand, Inferred) gives the Endymion Spell Counter engine a fairly reliable start, but the engine itself is thin, with only two Endymion and one Magister and Reflection, so the start depends on Spell Counter timing. Interaction is the strongest part: Endymion, Cerberus, Jackal King and Garuda, plus Droll & Lock Bird and Accesscode Talker, give layered destruction and negation text, which earns the end-board score rather than any popularity signal. Conversion is judged from card text only because no boards were recorded, so the ceiling and median scores are Inferred and not averaged from card scores. The score is held down by a 20% exact-name purity (Mythical Beast, Spellbook, Dark Magician, Diabellstar and Azamina pieces compete for the same slots), a Main Deck with 44 off-archetype copies, and an empty Side Deck that leaves no post-side plan. Meta Power is null because no dated metagame sample is supplied.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 47, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Empty Side Deck (-4); Engine conflicts (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 56.6 + TR 50 gives 55.6; modifiers -7 applied, rounded to 49

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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

• Dense searcher package (15 searcher-text cards) gives a high chance of a live starter
• Layered destruction and negation: Endymion, Cerberus, Jackal King, Garuda, Droll & Lock Bird, Accesscode Talker
• Large Extra Deck with 2800-3000 ATK boards and multiple Link routes

Weaknesses

• Exact-name purity 20%; many engine pieces belong to different sub-archetypes
• No Side Deck, so no post-side adaptation
• Negation and hand-trap density is thin for going-second control (one Droll)

Critical choke points

• Spell Counter count gates the Endymion and Servant pendulum summons
• Only 2 Endymion copies and 1 Magister/Reflection form the main engine body

Recommended changes

Evidence & confidence

• Verified: Legal under master-duel ban list: Instant Fusion and WANTED Limited at 1 copy; Droll & Lock Bird Semi-Limited at 1 of 2; Main 40, Extra 15, Side 0 within master-duel size rules; Card stats and text from resolved card data (e.g. Endymion 2800 ATK, Red-Eyes Dark Dragoon 3000 ATK); Exact-name purity 20% (11 of 55 copies)
• Inferred: P(at least one searcher in hand5) 0.92; Interaction density and end-board quality from removal and negation text; Recovery plan through Spell Power Mastery recursion and Mythical Institution
• Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit (no tournament_context)
• 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/second, matchup, brick/starter/OTK rates) Meta Power provisional without a dated metagame sample usage_statistics marks Millennium-Eyes Restrict, Azamina Ilia Silvia, Azamina Mu Rcielago, Dark Magician of Destruction, Promethean Princess, Artemis, Crowley, Heavymetalfoes Electrumite, Hiita, I:P Masquerena, Beyond the Pendulum, S:P Little Knight and Red-Eyes Dark Dragoon as in_this_deck false, but cards[] lists them in the Extra Deck; the usage join is inconsistent and core_present_pct 48 is unreliable deck title is null, so the deck name uses the archetype only
