Therions Deck #767620 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 33/100 (±10 · Confidence: Low)

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

Legality

Main 56 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Boss monsters from the Extra Deck (Chimeratech Rampage, Chaos Angel, Therion King Regulus, Vallon, Cyber Dragon Nova is not in the list) reached through Power Bond, Fusion or Link routes; none of this is confirmed by recorded boards.; Hand-trap and negation control that trades 1-for-1 with the opponent's engine until a boss lands.
• Turn 1 (going first): Open on a searcher (Chaotic Elements, Cyberdark Realm, Cyber Dragon Core, Infinite Impermanence as a set-up trap) into a level 5 body or Cyber Dragon, then Link or Xyz from the Extra Deck. Hand traps are held for the opponent's turn, so the going-first turn is light on interaction.
• Turn 2 (going second): Hold Ash Blossom, Droll and Ghost Belle or Infinite Impermanence as hand traps against the opponent's first board, then use Regulus or Druiswurm as the answer. This plan depends most on the hand-trap count.
• Recovery: Search through Cyberdark Claw, Cyber Dragon Herz and Clockwork Night (the GY-recursion pieces) and Ghost Belle from the GY. These are text-only reads, not recorded lines.
• After siding: No side deck. Post-side adaptation is not possible in this list as submitted.

Why it scores here

This deck was capped because it is Illegal: Ash Blossom and K9-17 Izuna each run 3 copies against an OCG limit of 2, so the score is theoretical and structural-only. Its structural read comes from a consistent searcher density (24 searcher-text cards; P(at least one searcher in a 5-card opening hand) is about 0.95, Inferred) and a 12-card hand-trap and negation suite that covers the opponent's going-second and first-board interaction. Its ceiling and median cannot be measured because no recorded boards exist. The Extra Deck has a boss-monster package, but the Therion identity is a single card and the main deck is spread across about 10 sub-archetypes (Cyber Dragon, K9, Cyberdark, Mulcharmy, Bystial and others), which weakens engine cohesion and makes the list hard to pilot. Popularity and archetype share earned no points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary, Stun secondary (structural only; the Stun weights were not used). Structural ≈ 47, Going First ≈ 42, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal copy-limit violation (cap) (-10); Engine conflict / sub-archetype spread (-2). Final formula: Illegal: capped, theoretical/structural-only. 0.80*Structural(47) + 0.20*TournamentReliability(35) ≈ 45 before modifiers, then −12 modifiers → 33

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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

• 24 searcher-text cards give high access to a plan in the opening hand (Inferred)
• 12 hand traps plus negation and removal text cover the opponent's interaction (Inferred)
• Extra Deck has several 2500-3500 ATK bosses and Power Bond gives a big Fusion route (Verified card text, Inferred use)

Weaknesses

• Illegal copy limits on Ash Blossom and K9-17 Izuna (Verified)
• No side deck, so no post-side plan (Verified)
• Therion identity is a single card (Verified)
• Sub-archetype spread across about 10 groups weakens engine cohesion (Verified composition, Inferred consequence)
• Only 1 copy of many key engine pieces; 23 singletons (Verified)

Critical choke points

• Fusion and Power Bond route rests on 1-copy Cyber Dragon monsters (Inferred)
• Going-second plan depends on hand traps that become dead cards on the opponent's turn (Inferred)

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom and K9-17 Izuna at 3 copies vs limit 2; Main 56, Extra 14, Side 0 within OCG size rules; Archetype purity 0% exact-name; 36 distinct main cards; Card text for the searcher, hand-trap and negation roles
• Inferred: Searcher access P ≈ 0.95 in a 5-card opening hand; Hand-trap dead-card risk and brick estimate; Fusion and Power Bond route reliability; Engine cohesion read across sub-archetypes
• Provisional: Meta and format fit (no dated meta); Going-first and going-second power splits
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and pilot record absent One passcode (10443957) unresolved; counted as main without card data No win-rate telemetry; going-first and going-second splits are Inferred Meta Power provisional; no dated metagame sample
