Earthbound Deck #756259 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±5 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Tempo
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Fusion or Synchro summon a large Memento or Artmage monster (Mementoal Tecuhtlica - Combined Creation at 5000 ATK, Mementomictlan Tecuhtlica - Creation King, Artmage Diactorus) from the Extra Deck; Link and Synchro pressure through Yummy monsters and Earthbound Immortal Aslla piscu (2500 ATK, direct attack)
• Turn 1 (going first): Opening-hand Memento and Artmage starters (Mementotlan Goblin, Mementotlan Shleepy, Mementotlan Mace, Effect Veiler) feed a Fusion or Special Summon chain; the plan depends on drawing one of the 3-copy starters, about a 34% chance in a 5-card hand (Inferred)
• Turn 2 (going second): Six-card hand, with Effect Veiler and the Artmage negation traps (Artmage Impasto -Recapture-) as the only hand-trap and negation answers; a 39% chance of drawing at least one 3-copy hand trap (Inferred)
• Recovery: Memento monsters recycle from the GY through Mementotlan Ghattic, Mementotlan Angwitch and Mementotlan Bone Back; Artmage Litera returns Artmage cards from the GY (text read, Inferred)
• After siding: None: the side deck is empty, so there is no post-side adaptation

Why it scores here

The deck is Illegal in OCG: Cupsy★Yummy Way is Forbidden and is run once, so the list is scored only as a structural, theoretical read with a low cap. The system mixes three sub-archetypes (Memento 21 cards, Artmage 9, Yummy 7, plus Goblin and Earthbound support), and only 2 cards carry the exact Earthbound name (3.6% purity), so the engine coherence is weak. Starter access is moderate: each 3-copy starter has about a 34% chance of appearing in a 5-card opening hand, and searcher text covers about 94% of opening hands (Inferred). Extra Deck use is reasonable with 15 slots across Fusion, Synchro, Link and Xyz, but the side deck is empty and there is no combo data, so the ceiling and floor are not measured. The score comes from consistency, interaction density and the system as a whole, not from averaging the individual card scores, and popularity was not credited.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 39, Going First ≈ 38, Going Second ≈ 35, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist_exposure (-6); engine_conflicts (-4); illegal_cap (0). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + modifiers (-10) = 27, then capped at 20 because the deck is Illegal (theoretical structural read only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Redundant 3-copy starters (Goblin, Shleepy, Mace, Effect Veiler) give about a 34% chance of a starter in opening 5
• Searcher text is dense (16 cards), so the deck can usually find a missing piece
• Strong top-end threats: Mementoal Tecuhtlica (5000 ATK), Creation King and Earthbound Immortal Aslla piscu (2500 ATK, direct attack)
• Recursion through Memento GY effects supports recovery after a single interruption

Weaknesses

• Illegal in OCG because of Forbidden Cupsy★Yummy Way
• Three overlapping engine families with 3.6% exact archetype purity
• Empty side deck, so there is no post-side adjustment
• No recorded combos, so the floor and ceiling are unmeasured
• Ten or more multi-step conditional summons raise pilot load

Critical choke points

• Access to a Link-1 or Level-2 Synchro monster for the Yummy and Synchro summon conditions
• The Forbidden Extra Deck card removes a Synchro route entirely in OCG
• Effect Veiler and Artmage Impasto are the only negation answers, so a single hand trap decides many interactions

Recommended changes

Evidence & confidence

• Verified: Legality Illegal: Cupsy★Yummy Way is Forbidden and run 1 copy; Main deck 40 and Extra Deck 15 are within the OCG size rules; Side deck is empty; Exact archetype purity is 3.6% (2 of 55 archetype cards); Searcher text appears on 16 cards and removal text on 20
• Inferred: Going-first starter access about 34% per 3-copy card (hypergeometric); Going-second hand-trap access about 39% (hypergeometric); Engine conflicts from mixed Memento, Artmage and Yummy lines; Interaction and recovery quality from card text
• Provisional: Meta Power and matchup fit: no dated metagame sample supplied
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: meta-share and pilot match record absent No win-rate telemetry for going-first, going-second, matchup or brick rate Usage statistics list Red Dragon Archfiend-style core cards and none of this deck's core is present; the stats appear to belong to a different archetype, so they were not used Side deck is empty, so the post-side dimension (D12) rests on the absence of data Meta Power is provisional without a dated metagame sample
