Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 59 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos or Black Luster Soldier (3000 ATK each) and attack with Power Patron Link or Fusion beaters (Inferred from card text); Power Patron Extra Deck monsters such as Vidolium (5000 ATK, Pendulum), Junora (3100 ATK), Nerva (3300 ATK), Mediclius (3000 ATK) and Number 38 (3000 ATK)
• Turn 1 (going first): Search and set up with Mulcharmy, Ars Magna and Mind Shuffle draws, then reach a Light and Darkness Ritual or Medius-based board; hand traps are weaker going first (Inferred)
• Turn 2 (going second): Use Ash Blossom, Ghost Ogre, Kuriboh and Nibiru to answer the opponent's first board, then Ritual Summon into a 3000-ATK body (Inferred)
• Recovery: Mulcharmy and Ars Magna searchers plus Pot of Sloth to rebuild hand after a brick or a lost board (Inferred)
• After siding: None: the deck has no side deck, so no best-of-3 adaptation is available

Why it scores here

This deck is illegal as submitted: three copies of Ash Blossom and Joyous Spring against a Semi-Limited limit of two, so it cannot receive a normal Final Contextual score and is capped at 30 as a theoretical, structural-only read. Scored as a system, its strength is interaction and closing power: about ten hand traps and twelve negation-style effects, with 3000-ATK ritual and Power Patron threats. Its weakness is coherence: exact-name archetype purity is 13.5% across six sub-archetypes, and the ritual engine is gated by a single Light and Darkness Ritual (about 8% to appear in an opening five). No combo boards were recorded, so the floor and median are estimates. Popularity and archetype usage did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 55, Going First ≈ 48, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist_exposure (-12); engine_conflicts (-4); no_side_deck (-3). Final formula: Illegal deck, theoretical only: 0.80*55 + 0.20*42 = 52.4, plus modifiers -19 = 33.4, capped to 30 for copy-limit violation; Meta provisional

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

• Ten hand traps and twelve negation-style effects give layered interaction
• Several 3000-plus ATK threats across ritual, Power Patron and Extra Deck bodies
• Searcher density (about 25 cards) keeps the hand functional
• Extra Deck covers link, fusion, Xyz and synchro summons

Weaknesses

• Illegal: Ash Blossom run 3 copies against a limit of 2
• Low exact-name purity (13.5%) across six sub-archetypes, so engine coherence is weak
• Single Light and Darkness Ritual enables the ritual chain, which is rarely seen in an opening hand
• No side deck, so no post-side adaptation
• No recorded combo boards, so conversion and floor are unverified

Critical choke points

• Single copy of Light and Darkness Ritual gates the Black Chaos and Black Luster Soldier ritual lines
• Ash Blossom copy count is illegal; the list must drop to two copies to be legal

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring run 3 copies against legal limit 2 (Illegal); Main 59 and Extra 15 are within size rules; Side 0; Card text and banlist status for all 35 main and 15 extra distinct cards; Exact-name archetype purity 13.5%
• Inferred: Consistency and draw odds from the hypergeometric estimates; Going-first and going-second plan read from card text; Interaction density from negation and removal text flags
• Provisional: Meta Power (no dated metagame sample); Matchup coverage (D13); Tournament reliability
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry: going-first, going-second and matchup rates are unknown Meta Power is Provisional unless a dated metagame sample is supplied No guides attached (guides_evidence total 0) Usage stats show S:P Little Knight, I:P Masquerena and Ecclesia and the Dark Dragon as core cards not present in this list
