Nemeses Deck #773319 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Extra Deck Ritual Beast Ulti monsters (Fusion and Link) summoned by banishing Ritual Beast Tamer and Spiritual Beast pieces, plus Perfectron Hydradrive Dragon as a board-clearing finisher; Topologic Blaster Dragon and Underworld Goddess of the Closed World as high-ATK link beatsticks
• Turn 1 (going first): Open a Tamer or Spiritual Beast starter, Normal Summon into the Ritual Beast loop, and set up Ulti Fusion material; keep Ash Blossom and Maxx C up as interaction
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll and Lock Bird, Ghost Ogre and Snow Rabbit, Maxx C) to break the opponent's first combo, then rebuild through Tamer recursion
• Recovery: Recur Tamers and Spiritual Beasts from the banished zone through Ritual Beast Tamer Wen and Nemeses Corridor; Ritual Beast Ulti-Kimunfalcos can return banished Ritual Beast cards
• After siding: No side deck is registered, so no post-side plan exists in the export

Why it scores here

The deck's engine is the Ritual Beast core: 19 core copies give a 0.97 chance of at least one open in a 5-card hand, and three copies each of Tamer Elder, Spiritual Beast Tamer Lara and Spiritual Beast Cannahawk give 0.34 per card. Interaction is strong for OCG, with two Ash Blossom, Maxx C, Droll and Lock Bird, Ghost Ogre and Ghost Mourner, Crossout Designator and Psi-Blocker. The end-board is high-ATK Link and Fusion monsters such as Perfectron, Topologic and Underworld Goddess. Against that, the deck mixes at least five unrelated sub-archetypes (Harpie, Mulcharmy, Charmer, K9, Number), and only 1 of 55 archetype-named cards is an exact Nemeses card, so engine coherence is weak. The deck is also Illegal because three Forbidden cards are run, so the score is capped and reported as structural and theoretical only. Popularity and meta-share did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Combo considered but not blended numerically. Structural ≈ 51, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-12). Final formula: No reliable metagame, so Meta is provisional: 0.80*51 + 0.20*35 = 47.8; modifiers -12 gives 35.8; capped at 30 because the list is Illegal (theoretical and structural 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

• Ritual Beast core is dense (19 copies), so a starter is usually available
• Layered interaction: 2 Ash Blossom, Maxx C, Droll and Lock Bird, Ghost Ogre, Ghost Mourner, Crossout Designator, Psi-Blocker
• High-ATK Extra Deck closers: Perfectron 5000, Topologic 3500, Underworld Goddess 3000, Ulti-Gaiapelio 3200

Weaknesses

• Illegal in OCG: three Forbidden cards run
• Sub-archetype incoherence: only 1 exact Nemeses card; Harpie, Mulcharmy, Charmer, K9 and Number pieces dilute the engine
• No side deck registered, so no post-side adaptability
• No combos or tournament data, so the power read rests on text and probability

Critical choke points

• Tamer and Spiritual Beast pieces in hand or banished zone are needed for Ulti Fusions; losing them to one hand trap stalls the engine
• Forbidden cards must be removed before this list can be played legally

Recommended changes

Evidence & confidence

• Verified: Forbidden status of Triple Tactics Talent, Charmer Quartet in Bloom and Cross-Sheep; Main 40, Extra 15, Side 0 counts; archetype purity 1.8%; Core group of 19 copies with P(at least one in hand 5) = 0.9691
• Inferred: Starter consistency estimates from hypergeometric probabilities; Interaction breadth from card text; Going-first and going-second splits
• Provisional: Meta Power is null; matchup and format fit have no dated 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 are absent No win-rate telemetry for going-first, going-second, matchup, or brick rates Meta Power is provisional without a dated metagame sample No side deck registered
