Endymion Deck #774002 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Link and Fusion Summon Magistus/Endymion/Fairy Tail extra-deck monsters off the Regulus, Verre and Fairy Tail starter chain, then close with the boards those summons create (Inferred from card text); Direct attacks from Fairy Tail monsters and Endymion Empire recursion (Inferred from card text)
• Turn 1 (going first): Opening starter (Regulus, Verre, Luna or a Fairy Tail searcher) to add a second engine piece, then a Fusion or Link Summon; hand traps are held back to protect the line (Inferred)
• Turn 2 (going second): Hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Droll, Effect Veiler) interrupt the opponent's first board, then the engine rebuilds through Once Upon a Fairy Tail or Witchcrafter Genni (Inferred)
• Recovery: Search back through Spell Power Mastery, Fairy Tail Ball and Tails of the Fairy Tails, and recur Fairy Tail monsters from the GY or banishment (Inferred)
• After siding: Not evaluable: the side deck is empty (0 cards), so there is no post-side plan

Why it scores here

The list reliably opens an Endymion, Magistus or Fairy Tail starter in most hands: the archetype core has about a 97.7% chance of at least one piece in the opening five, though any single three-copy starter (for example Regulus) is only about 25% per opening hand, so the engine is accessible but not guaranteed on turn one (Inferred). Its interaction density is high, with 18 hand traps and 20 negation-text cards, which earns the strongest dimension on end-board interaction and a solid going-second read (hand-trap at least one in six is about 92%). Conversion and median output cannot be verified because no recorded boards exist, so combo ceiling and floor are text-only inferences and are kept near the middle. The score is capped by the legality status: five copy-limit violations, including three Forbidden cards, make the list Illegal, so the result is theoretical and structural only. Popularity and archetype usage were not counted as power, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo primary (about 85%) with Midrange secondary (about 15%) for hand-trap-heavy interaction; the profile weights below are the Combo table. Structural ≈ 52, Going First ≈ 48, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12). Final formula: Illegal list, so not a normal score: 0.80*Structural(52) + 0.20*TournamentReliability(40) = 49.6 before modifiers; banlist-exposure modifier -12 gives 37.6; capped to 25 as a theoretical, structural-only result (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 hand-trap and negation coverage (18 hand traps, 20 negation-text cards)
• High archetype-core access for an opening hand (about 98% for at least one core card in 5)
• Multiple independent starters and recursion (Fairy Tail Ball, Once Upon a Fairy Tail, Tails of the Fairy Tails)

Weaknesses

• Illegal list: three Forbidden cards and copy-limit overages on Ash Blossom and Droll
• Empty side deck, so no post-side plan
• Low archetype purity (10% exact name), spreading copies over several sub-archetypes
• No recorded boards, so the combo ceiling and median are unmeasured

Critical choke points

• Regulus, Verre and Fairy Tail - Luna starter density (3 copies each): roughly one in four opening hands contains each
• Extra-deck summon access through the Fusion and Link pieces (6 Fusion, 6 Link)

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 are within size rules; Five copy-limit violations and three Forbidden cards in the list; Hand-trap, negation and removal text counts from the card list; Exact-name archetype purity is 10%
• Inferred: Starter and archetype-core hypergeometric odds (Main-deck only); Going-first and going-second plans from card text; Interaction quality from negation and removal text
• Provisional: Meta and format fit (no dated metagame sample)
• 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 The usage_statistics in_this_deck flags contradict the card list for several Extra Deck cards (Fairy Tail - Wiccat, Endymion the Crescent Magistus, Artemis, Summon Sorceress, Zoroa the Magistus Verethragna, Teller of Fairy Tails, Weaver of Fairy Tails): they are listed as missing but appear in cards, so Extra Deck coverage is uncertain No win-rate, brick or matchup telemetry exists Meta Power is provisional without a dated metagame sample Side deck is empty, so no post-side evaluation is possible
