Earthbound Deck #752629 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Earthbound Immortal Ccapac Apu and Earthbound Servant Geo Grasha pressure through Earthbound Synchro/Fusion boards, with Psychic End Punisher as a secondary boss.; Earthbound Servant Geo Kraken and Geo Gremlina Extra Deck boards via Earthbound Fusion and Harmonic Synchro Fusion.
• Turn 1 (going first): Open Polymerization or Earthbound Prisoner Ground Keeper, search Earthbound Prison or Edge Imp material, then Synchro/Fusion into an Earthbound boss while holding Ash Blossom and Red Reboot as interaction.
• Turn 2 (going second): Use Ash Blossom, Infinite Impermanence, Red Reboot, Droll & Lock Bird and Maxx "C" to disrupt the opponent's first board, then rebuild through Earthbound Prisoner Stone Sweeper and Line Walker.
• Recovery: Recycle through Frightfur Patchwork, Edge Imp Chain and Earthbound Fusion from the GY, and rebuild via the Earthbound Field-based Normal Summon.
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adapt between games in the submitted form.

Why it scores here

The deck reliably opens its starters at roughly one-in-three odds per 3-copy card in a 5-card hand (Inferred hypergeometric estimate), with searchers such as Frightfur Patchwork and Earthbound Prisoner Line Walker giving it some extra consistency. Its interaction suite (Ash Blossom, Infinite Impermanence, Red Reboot, Droll & Lock Bird, Maxx "C", Singularity Fiend) is dense and supports a going-second plan. Closing power comes from Earthbound Immortal Ccapac Apu and Geo Grasha, and a 40-card main with no Side Deck limits adaptation. The score is not driven by Earthbound's popularity, and no card scores were averaged. Because three Forbidden cards and one over-limit Limited card are present, the list is illegal and this is a structural-only, theoretical score capped at 35.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 50, Going First ≈ 52, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-12). Final formula: Illegal list: structural-only theoretical score; 0.80*Structural + 0.20*TournamentReliability = 48, minus banlist-exposure modifier (-12) = 36, capped at 35 for an illegal deck. Meta provisional.

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

• Dense interaction package with seven hand traps and multiple negation and removal effects
• Multiple searchers (12 searcher-text cards) and GY recursion add redundancy
• Extra Deck carries several high-ATK boss options (Ccapac Apu, Grasha, Psychic End Punisher)

Weaknesses

• Illegal as submitted: three Forbidden cards and one over-limit Limited card
• No Side Deck (0 cards), so no post-side adaptation
• Low archetype purity (43.6% exact name); many generic and off-theme slots
• No recorded combo boards, so the combo floor and median cannot be measured

Critical choke points

• Polymerization or Earthbound Prisoner Ground Keeper as the sole early-engine entry (about 0.34 chance per 3-copy card in 5 cards)
• Earthbound Prison / Field-zone dependence for several Earthbound effects
• Forbidden Extra Deck monsters removing Synchro/Fusion options

Recommended changes

Evidence & confidence

• Verified: Legality: three Forbidden cards and Chicken Game over the Limited copy limit (Illegal); Main 40 / Extra 15 / Side 0 counts within OCG size rules; Hypergeometric draw probabilities from the resolved list; Exact-name purity 43.6% and Side Deck empty
• Inferred: Engine consistency estimates from draw probabilities; Interaction quality from card text; Going-first and going-second estimates from role analysis
• Provisional: Meta Power and matchup fit (no dated meta sample or tournament link)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta share and pilot record absent No win-rate telemetry for going-first, going-second, matchup, brick or starter rates Meta Power provisional; no dated metagame sample Side Deck empty, so post-side performance cannot be assessed
