Endymion Deck #770530 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 39/100 (±12 · Confidence: Low)

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

Legality

Main 42 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Endymion/Magistus/Fairy Tail Link and Fusion boards (Endymion, Selene, Summon Sorceress, Zoroa Verethragna, Aiwass) reached through Regulus, Verre and Fairy Tail searchers; no recorded combo supports a specific line.; Invoked Oceanus and Teller of Fairy Tails as Fusion boards; Garura and Mudragon are present in the Extra Deck only as fallback bodies.
• Turn 1 (going first): Open Regulus or a searcher (Matchgiru, Luna, Verre, Genia), search an Endymion or Fairy Tail enabler, and go to a Link or Fusion board through Super Polymerization and Instant Fusion (Inferred, no combo data).
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Droll & Lock Bird and Ash-style negations for the opponent's first board, then rebuild through the searcher density (Inferred).
• Recovery: Recycle Matchgiru and Spenta from the GY, use Fairy Tail Ball and Once Upon a Fairy Tail to reload the hand, and rely on Mulcharmy draw effects when the board is empty (Inferred).
• After siding: No Side Deck is registered, so there is no post-side plan (side_count 0).

Why it scores here

This list is scored as a whole system and not as an average of card scores. Its strongest feature is access: Regulus is live in about 32% of going-first 5-card hands, and 16 searcher-text cards give about 92% odds of at least one searcher, so the engine is usually reachable on T1-T2 (Inferred). Interaction is also dense, with 7 hand traps and 12 negation-text cards giving about 69% odds of a hand trap by going second. The deck is weakened by a diffuse core: exact Endymion purity is only 14%, and Magistus, Fairy Tail and Mulcharmy together account for 49 off-archetype copies, which adds conflicts and bricks. The deck breaks Illegal copy limits on two cards (Ash Blossom and Super Polymerization at 3 copies, legal limit 2) and has no Side Deck, so the score is a theoretical, structural-only read capped low. Popularity and usage stats are absent, so they earned no points.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 52, Going First ≈ 52, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal copy-limit violations (-12). Final formula: Theoretical/structural-only: 0.80*Structural(52) + 0.20*TournamentReliability(45) = 50.6, then capped by the Illegal-deck rule (copy-limit violations) with a -12 modifier, giving 39. Not a normal Final Contextual score.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · 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 density (16 searcher-text cards) gives about 92% odds of at least one search in a 5-card hand (Inferred)
• Layered interaction: 7 hand traps plus 12 negation-text cards give about 69% going-second hand-trap odds (Inferred)
• Flexible Extra Deck covering Link, Fusion and XYZ for multiple boards

Weaknesses

• Exact archetype purity only 14%; the deck spans Endymion, Magistus, Fairy Tail and Mulcharmy with 49 off-archetype copies (Verified)
• Illegal: Ash Blossom and Super Polymerization run 3 copies against a limit of 2 (Verified)
• No Side Deck, so no post-side adaptability (Verified)
• Mulcharmy draw effects require an empty field, which conflicts with the board-based engines (Inferred)

Critical choke points

• Regulus or a searcher is the main T1 starter; no second independent starter is confirmed (Inferred)
• Fairy Tail - Snow needs 7 other cards banished from hand, field and GY, which is a costly late-game line (Verified text)

Recommended changes
