Unchained Deck #769075 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 18/100 (±5 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Control, Toolbox
• Format: ocg

Legality

Main 50 / Extra 13 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Extra Deck boards (Link, Fusion and Synchro monsters) built from Sacred Beast and Phantasm summons, closed by large-ATK Fusion monsters such as The Chaotic Phantasmal Sacred Beasts.; Fiendsmith Link and Fusion chain (Fiendsmith's Lacrima, Fiendsmith's Desirae) as a second engine when the Phantasm line is stopped.
• Turn 1 (going first): Search or summon a Sacred Beast starter (Summoner of the Sacred Beasts, Martyr of the Sacred Beasts), then reach a Level 10 Sacred Beast to Special Summon Infinity or Calamity. Keep Ash Blossom, Infinite Impermanence or Solemn Judgment up for the opponent's turn.
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle or Nibiru as hand traps against the opponent's first summon or search, then rebuild from the Graveyard with Lacrima the Crimson Tears and Sacred Beasts Released.
• Recovery: Recursion through Sacred Beasts Released (GY effect), Martyr of the Sacred Beasts and Fiendsmith's Lacrima from the Graveyard. Mulcharmy monsters draw cards when the hand is small.
• After siding: No side deck is registered (side_count 0), so there is no post-side plan.

Why it scores here

The deck is Illegal: Ash Blossom & Joyous Spring is run three times against an OCG limit of two, so it receives only a theoretical, structural score and the final value is capped at 18. Structurally it is a multi-archetype shell rather than a pure Unchained deck: exact-name purity is 3.2%, with Phantasm (22), Fiendsmith (7), Mulcharmy (6) and generic cards (18) making up the rest. Its interaction density is reasonable, with 11 hand traps, 15 negation-text cards and 19 removal-text cards, which earns the endboard-interaction score. The probability estimates give a 27.6% chance of at least one Sacred Beast starter in a 5-card opening hand and a 76% chance of at least one archetype-core card, but the consistency score stays moderate because the core is spread across three archetypes and there are no recorded boards to confirm conversion. The score comes from consistency and interaction on the system, not from the popularity of the Unchained name and not from averaging the card scores; combo-based dimensions are text-only inference because no boards were supplied.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Control considered only as a qualitative secondary, not as a weight blend. Structural ≈ 44, Going First ≈ 40, Going Second ≈ 36, Meta = provisional, Tournament Reliability ≈ 28. Modifiers: banlist_exposure (-8); dependence_on_extra_deck_cards (-4); illegal_deck_cap (0). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*44 + 0.20*28 = 40.8; context modifiers -12 gives 28.8; Illegal-deck cap applied gives 18 (theoretical/structural only, not a normal score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.28 · 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

• Large interaction package: 11 hand traps, 15 negation-text cards and 19 removal-text cards.
• Multiple independent starters across Sacred Beast, Fiendsmith and Mulcharmy lines, so a single dead card rarely stops the whole hand.
• High-ceiling Extra Deck finishers (Infinity, Calamity, Chaotic Phantasmal at 5000 ATK).

Weaknesses

• Illegal as built: Ash Blossom is run 3 times against an OCG limit of 2.
• Low exact-archetype purity (3.2%): the declared Unchained name does not describe the actual engine, which makes the deck harder to judge and to tune.
• Six Limited cards and one-copy Fiendsmith and Phantasm engine pieces create a fragile, single-choke-point build.
• No side deck registered, so there is no post-side plan.

Critical choke points

• Ash Blossom over the copy limit: the deck cannot be entered in an OCG event until one copy is removed.
• Fiendsmith's Lacrima and Fiendsmith's Desirae are single copies, so losing either to interaction removes the Fiendsmith finisher.
• Sacred Beast Level 10 requirements: a Level 10 Sacred Beast must be reached to summon the Phantasm finishers, with few backups.

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring is run 3 times against an OCG limit of 2 (Semi-Limited).; Main Deck is 50 cards (legal range 40-60), Extra Deck 13 (legal range 0-15), Side Deck 0 (legal range 0-15).; Six Limited cards are present at 1 copy each (legal).; Exact-name archetype purity is 3.2%, and Phantasm (22), Fiendsmith (7) and Mulcharmy (6) are the main sub-archetypes.
• Inferred: Interaction density is high (11 hand traps, 15 negation-text, 19 removal-text).; The starter probabilities (0.276 for a 3-copy line in 5 cards; 0.763 for the archetype-core group) imply moderate opening-hand consistency.; The ceiling is high (Infinity, Calamity, Chaotic Phantasmal) but the median is unknown without recorded boards.
• Provisional: Meta Power and format fit (no dated meta sample; tournament_context unavailable).; Post-side plan (no side deck).
• 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 are absent. No win-rate telemetry (going-first/second, matchup, brick/starter rates). Meta Power is Provisional unless a dated metagame sample is supplied. The deck title is null and the side deck is empty.
