Altergeist Deck #768035 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 64/100 (±6 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link-summon boss monsters (Adminia, Primebanshee, Hexstia, Memorygant, Dragvirion) from a searcher-fed Altergeist engine and close with 2100-3000 ATK bodies; Grind out card advantage through Altergeist recursion (Revitalization, Peritrator, Marionetter) while negation traps protect the board
• Turn 1 (going first): Turn 1 Normal Summon Meluseek or Malwisp, search an Altergeist monster with a searcher, then pivot into a two-card link route (Pookuery or Malwisp as material) to reach a 2+ link boss
• Turn 2 (going second): Use hand traps (Ghost Ogre, Ghost Belle, Effect Veiler, Droll & Lock Bird, Evenly Matched, Kunquery) to answer the opponent's starter, then rebuild through the GY with Revitalization or Peritrator
• Recovery: Recover Altergeist Link monsters from the GY with Altergeist Revitalization, reuse Pookuery and Multifaker from the GY, and re-extend through Protocol or Haunted Rock
• After siding: No side deck is registered, so no post-side plan can be evaluated; the default plan is the main deck as built

Why it scores here

The deck reliably opens a functional plan: the archetype core group (19 copies) has a proxy P(at least one in a 5-card opening hand) of about 0.97, and the 15 searcher-text cards give about 0.92 for at least one searcher in hand, so the engine is usually live by turn 2 (Inferred from hypergeometric estimates). It converts that plan into pressure through a Link/Synchro boss set with 2100-3000 ATK bodies and recursion from the graveyard, which the evidence supports only through card text because no recorded boards exist. It survives disruption reasonably well through multiple independent starters (Meluseek, Malwisp, Pookuery), layered negation traps and seven hand traps, which give about 0.71 for at least one hand trap in a 6-card going-second hand. Its weak points are the missing side deck, the absence of a dated metagame or tournament link, and three Limited cards that reduce consistency. This score was built from consistency, interaction and closing power on the system; it did not come from Altergeist being a popular archetype or from averaging the individual card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 69, Going First ≈ 66, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 64. Modifiers: banlist exposure (-2); engine conflicts and off-archetype load (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; 0.80*68.6 + 0.20*64 - 4 = 63.7, rounded to 64)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ 0.03 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Compact Altergeist engine with 3-copy starters and a searcher package at about 0.92 hit rate
• Redundant starters (Meluseek, Malwisp, Pookuery, Multifaker) give independent lines after disruption
• Layered negation: 7 hand traps plus negation traps (Protocol, Haunted Rock, Dragvirion, Kunquery, Hexstia)
• High-ATK Link and Synchro boss set (2100-3000 ATK) with recursion from the GY
• Legal list with no violations; all three Limited cards are one copy each

Weaknesses

• No side deck registered, so there is no post-side adaptation
• No recorded boards, so combo floor, median and ceiling are text-only inference
• Off-archetype and generic load (13 generic main cards plus Endymion, Charmer, Knightmare and Salamangreat Extra cards) dilutes engine coherence
• Three Limited cards (Droll & Lock Bird, One for One, Terraforming) limit consistency and make the list fragile to a banlist change
• Several core staples from the usage baseline are absent (Maxx C, Ash Blossom & Joyous Spring, Infinite Impermanence, Crossout Designator, Linkuriboh)

Critical choke points

• The 3-copy engine starter (Meluseek, Multifaker, Pookuery) is 0.34 each in an opening hand of 5, so the first-turn line can depend on a single searcher
• Droll & Lock Bird and Ghost Belle are the main going-second interaction; losing them to a hand trap or opponent's Droll opens the board
• Link-material reliance on the Altergeist monster set means one removed or negated monster can break the Link route

Recommended changes

Evidence & confidence

• Verified: Legal OCG list: 40 main and 15 extra with 0 side (legal range 40-60 / 0-15); Three Limited cards at 1 copy each: Droll & Lock Bird, One for One, Terraforming; Archetype exact-name purity 67.3%; 13 generic and 5 off-archetype main or Extra cards; Usage baseline: 9 of 20 core cards present by main-deck flag (12 counting Extra-deck cards, see data_gaps)
• Observed: No recorded boards in combos_evidence (total_combos = 0); no observed combo frequencies exist
• Inferred: P(>=1 archetype core card in opening hand of 5) about 0.97 (proxy group estimate); P(>=1 hand trap in going-second hand of 6) about 0.71; P(>=1 of 3 copies of a starter in hand of 5) = 0.34 per 3-copy card; Interaction density is high from text flags (9 negation, 12 removal); Combo ceiling and boss-closing rating from card text only
• Provisional: Meta Power is null; no dated metagame sample is supplied; D12 side deck and D13 matchup fit are placeholders without post-side or meta data
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record are absent no side deck registered: post-side plan cannot be evaluated usage_statistics in_this_deck flag appears to check the main deck only: Altergeist Hexstia (3), Altergeist Memorygant (1) and Selene (2) are present in the Extra deck but flagged in_this_deck = false, so missing_core overstates the gaps no win-rate telemetry exists in YGOVN (going-first/second, matchup, brick and starter rates): these are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
