Altergeist Deck #773310 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 54 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Altergeist Link and Synchro monsters (Adminia, Dragvirion, Memorygant absent) converting board advantage through recursion and Link Summons; end-board is Link-based; Direct attacks from Meluseek and Peritrator, plus Super Starslayer TY-PHON as a late-game Xyz beater
• Turn 1 (going first): Open a Altergeist starter (Multifaker, Marionetter, Meluseek, Pookuery) with a trap-set or Normal Summon line, use Personal Spoofing or Altergeist Protocol to protect the engine, then Link Summon into the Extra Deck link monsters
• Turn 2 (going second): Use the hand-trap suite (Ash Blossom, Infinite Impermanence, Evenly Matched, Solemn Strike and Warning) to slow the opponent's combo, then rebuild the board through Altergeist recursion
• Recovery: Re-use GY Altergeist monsters via Revitalization, Pookuery and Haunted Rock; the rebuild depends on the GY and on recursion, not on a single card
• After siding: Not evaluable: the deck has an empty side deck, so there is no post-side plan in the evidence

Why it scores here

The deck reliably opens an Altergeist starter: 35 Altergeist-named copies give a hypergeometric P(at least one archetype-core card in a 5-card opening hand) of about 0.997, which earns the engine-access score. Interaction is dense, with 10 hand traps, 15 negation-text cards, and Solemn and Infinite Impermanence layers, and that drives the end-board interaction score. Conversion and median output are scored from text only, because the deck supplies no recorded boards, so both scores carry low confidence. The deck is Illegal (3 copies of Ash Blossom against a limit of 2), so the score is capped at 35 and labelled theoretical and structural-only. The score comes from consistency, recursion, and interaction on the deck as a system, not from averaging card scores, and the Altergeist archetype's popularity earned no points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-10). Final formula: Midrange structural 56.5 -> 0.80*56 + 0.20*45 = 54, plus banlist modifier -10 = 44, then Illegal cap applied -> 35 (theoretical, structural-only; Meta provisional)

Probability & combo summary

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

Strengths

• Core engine access is very high because 35 Altergeist-named copies sit in the Main Deck (Inferred from hypergeometric odds)
• Layered interaction: 10 hand traps and Solemn-family negations give answers at several points in the turn
• Recursion routes (Revitalization, Pookuery, Haunted Rock, Silquitous) allow re-entry after disruption

Weaknesses

• The list is Illegal: Ash Blossom & Joyous Spring is run at 3 copies against a limit of 2
• No recorded boards, so the combo ceiling and median cannot be measured
• Side deck is empty, so there is no post-side adaptation
• Hand-trap and tech density (26 cards) can leave hands dead without a board

Critical choke points

• Ash Blossom 3-copy limit breach: the list cannot be played as submitted
• Dependence on Altergeist Link Monsters in the Extra Deck to finish the turn; missing core Link monsters (Memorygant, Adminia, Primebanshee) reduce the closing options shown in the usage core

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring is run at 3 copies against a Semi-Limited OCG limit of 2 (legality violation); Main Deck 54 cards and Extra Deck 15 cards are within the OCG size rules; Altergeist core is 35 exact-name copies (purity 50.7%); Usage core present 18 of 24 cards
• Inferred: P(at least one archetype-core card in 5-card hand) approximately 0.997; Hand-trap availability on going second approximately 0.73; Recursion routes give re-entry after disruption
• Provisional: Meta Power is null; matchup fit (D13) rests on no meta sample
• Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for going-first, going-second, matchup, or brick rates Side deck is empty, so post-side plan cannot be evaluated No guides attached for the archetype Meta Power is Provisional without a dated metagame sample
