Earthbound Deck #769084 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Synchro bosses built from Resonator tuners: Red Dragon Archfiend (2 copies, 3000 ATK), Red Nova Dragon, Red Supernova Dragon, Bystial Dis Pater; Bystial and Archfiend recursion (Crimson Gaia, Red Zone, Vision Resonator, Chaos/Crimson Call) after the first board is answered
• Turn 1 (going first): Open a Tuner (Resonator, Ghost Belle, Soul Resonator, Ghost Mourner) with a starter, chain Normal/Special Summons into a Level 8+ Synchro; hold Ash Blossom or Ghost Belle for the opponent's first activation (Inferred)
• Turn 2 (going second): Use hand traps (7 copies, about 56% chance of at least one in a 6-card hand) to answer the opponent's first summon, then Synchro from what remains (Inferred)
• Recovery: Recover Resonator monsters from the GY through Red Dragon synchro effects and reuse Dragon's Mind and Red Zone; the lines are text-derived, not observed (Inferred)
• After siding: None: the deck runs 0 side cards, so there is no post-side plan

Why it scores here

The score is a structural read of the list as a system, capped because the deck is illegal. Starter access is the strongest part: 18 copies of the archetype core give about 86% odds of at least one core card in a 5-card opening hand (Inferred), and 15 Synchro monsters give the deck real end-board reach. Interaction is dense, with 7 hand traps, Solemn Judgment, Harpie's Feather Duster and Dragon's Mind, so the deck can contest a going-second board. Median output and recorded combo conversion cannot be scored because no boards were supplied, so D3 and D4 rest on text reading only. The deck runs no side cards and has no tournament or meta data, which keeps D12 and D13 low and provisional. The score comes from consistency, interaction and closing power on the system, not from averaging card scores, and not from Earthbound's popularity, since the Earthbound archetype purity is 1.4%. Ash Blossom at 3 copies breaks the OCG copy limit, so the Final Contextual score is capped at 25.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-8); no_side_deck (-4). Final formula: Illegal cap (Step 2): normal formula 0.80*60 + 0.20*50 = 58, plus modifiers -12 = 46, capped to 25 as a theoretical/structural-only read

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · key two-card combo ≈ — · full-brick estimate ≈ 0.14 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense starter access: 18 core copies give about 86% odds of a core card in the opening hand (Inferred)
• Layered interaction: 7 hand traps plus Solemn Judgment, Dragon's Mind and Harpie's Feather Duster (Inferred)
• Strong Synchro end-board: Red Dragon Archfiend, Red Nova Dragon, Red Supernova Dragon, Bystial Dis Pater (Verified text)
• Compact main deck with 32 distinct cards and 3-of redundancy on tuners (Verified)

Weaknesses

• Illegal in OCG: Ash Blossom & Joyous Spring at 3 copies against a limit of 2 (Verified)
• No side deck, so no best-of-3 adaptation (Verified)
• No recorded boards, so floor, median and ceiling are unmeasured (Verified gap)
• Archetype label Earthbound does not match the list: 1.4% exact-name purity (Verified)

Critical choke points

• Tuner density: most Synchro lines need a specific Tuner from hand, so hand-trap-only hands fail to convert (Inferred)
• Single-copy Limited cards (Bystial Magnamhut, Bystial Druiswurm, The Bystial Lubellion, Droll & Lock Bird, Solemn Judgment, Harpie's Feather Duster, Foolish Burial) mean a removed copy cannot be replaced (Verified)

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring is 3 copies against a legal limit of 2 (OCG Semi-Limited); Main 57 and Extra 15 counts are within the 40-60 and 0-15 size rules; Side deck is 0 cards; Copy histogram and Extra Deck breakdown match the card list; Archetype exact-name purity is 1.4%
• Inferred: At least one core card in 5-card hand about 0.86; full brick about 0.14; Hand-trap odds of at least one in a 6-card hand about 0.56; Synchro lines and interaction read from card text; Going-first and going-second power estimates
• Provisional: Meta Power (null, no dated sample); Matchup and tournament fit (D13 neutral)
• Data gaps: Illegal list (Ash Blossom copy limit): structural score only No combos supplied: D3 and D4 are text-only Inconsistent usage stats: usage_statistics marks Red Dragon Archfiend and Bystial Dis Pater as in_this_deck=false, but the cards list has 2 and 1 copies of them in the Extra Deck. The cards list was used. No tournament link: archetype meta-share and match record absent No win-rate, going-first/second, or brick telemetry in YGOVN Meta Power is provisional without a dated metagame sample No side deck, so D12 and post-side plans cannot be checked
