Endymion Deck #773488 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Stun, Toolbox
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Fusion, Link, and Xyz boss summons from the Extra Deck (Teller of Fairy Tails, Aiwass, Zoroa the Magistus Verethragna, Summon Sorceress) built off Endymion, Fairy Tail, and Magistus Spellcaster engines (Inferred from card text; no combo boards supplied); Hand-trap and negate interaction (Ash Blossom, Ghost Ogre, Ghost Belle, Nibiru, Droll & Lock Bird) to protect a going-second board (Inferred)
• Turn 1 (going first): Open a Spellcaster starter (Regulus, Verre, Fairy Tail Luna, Genni) and extend through Verre Magic or Fairy Tail Ball into an Extra Deck summon; no recorded line exists (Inferred)
• Turn 2 (going second): Hold 2-3 hand traps and negates (Ash, Ghost Belle, Ghost Ogre, Evenly Matched) to answer the opponent's first board, then convert through Fusion or Link summons (Inferred)
• Recovery: Recursion through Witchcrafter Creation, Fairy Tail Ball, and Once Upon a Fairy Tail from GY and banish zones (Inferred from card text)
• After siding: Not evaluable: Side Deck size is 0, so no post-side plan exists in this list

Why it scores here

This list is illegal under TCG rules: Ash Blossom & Joyous Spring and Super Polymerization are each run three times against a Semi-Limited limit of two, so the deck is capped and scored as structural-only. Its engine is real but split: the archetype core (Endymion, Magistus, Fairy Tail, Mulcharmy, Forbidden) gives only 10% exact-name purity, yet the Spellcaster and Extra-Deck summon routes still give the list multiple ways to reach a boss. Interaction is the strongest system trait, with 13 hand traps, 15 negation-text cards, and Forbidden Crown and Droplet backing the hand traps, which supports going-second play. Floor and median output cannot be measured because no combo boards are supplied, so the ceiling is text-only inference. Popularity and archetype usage stats confirm the list is accessible but did not earn points. No card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo primary with Stun secondary (not applied as a blend; Combo weights used). Structural ≈ 55, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: Illegal list: structural-only and capped. Raw 0.80*55 + 0.20*40 - 12 = 40, capped at 35 because the list breaks copy limits. Meta provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.79 · 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

• Very high archetype-core access (0.977 in opening 5) so an Endymion, Magistus or Fairy Tail starter is almost always present
• Dense interaction: 13 hand traps, 15 negation-text cards, Forbidden Crown and Droplet
• Multiple Extra-Deck boss routes (Fusion, Link, Xyz) with 2900 and 2400 ATK ends

Weaknesses

• Illegal copy counts on Ash Blossom and Super Polymerization
• Exact-name purity of 10% across five sub-archetypes, so the engines conflict
• No side deck and no post-side plan
• Many single-copy tech and Limited cards that create brick-like hands

Critical choke points

• Any starter that requires Regulus, Verre or Fairy Tail Luna to live in hand; without one, the engine does not start
• Illegal copy limits: the list must drop one Ash Blossom and one Super Polymerization before any normal score applies

Recommended changes

Evidence & confidence

• Verified: Ash Blossom and Super Polymerization each run 3 copies against a Semi-Limited limit of 2; Main deck is 55 cards (legal range 40-60); Extra deck is 15 cards (legal range 0-15); side deck is 0; Archetype core P(>=1 in opening 5) = 0.977 from the hypergeometric table; Exact-name archetype purity is 10%
• Inferred: Engine accessibility and brick estimates from hypergeometric odds and card text; Interaction and resilience reads from hand-trap and negation text; Going-first and going-second plans from card text only
• Provisional: Matchup and format fit (no dated metagame sample); Floor and median output (no recorded boards); Meta power (null)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and pilot record are absent No win-rate telemetry; going-first and going-second splits are Inferred Meta Power is Provisional unless a dated metagame sample is supplied No side deck; post-side scoring is not possible
