Therions Deck #772746 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 47/100 (±6 · Confidence: Medium)

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

Legality

Main 58 / Extra 14 / Side 0 — status: Legal with warning.

Identity & game plan

• Win condition: Fusion and Link summons of Cyber Dragon or Cyberdark bodies into large attackers such as Cyberdark End Dragon, Cyber End Dragon and Cyber Eternity Dragon, supported by Power Bond damage; Therion King Regulus and Cyber Dragon Core as board pressure, plus the Cyber Dragon Core and Cyberdark Realm searcher chain
• Turn 1 (going first): Normal Summon a searcher-engine monster (Cyber Dragon Core or Cyberdark Realm), search a Cyber or Cyberdark piece, then build toward a Fusion or Link summon while holding Infinite Impermanence or Cosmic Cyclone for the opponent's first answer
• Turn 2 (going second): Hold hand traps (Infinite Impermanence, D.D. Crow, Artifact Lancea, Ghost Belle, PSY-Framegear Gamma) and go for a Fusion or Link summon once the opponent commits a board, using Raigeki or Lightning Storm to clear
• Recovery: Recursion from the GY through Cyberdark Edge, Cyberdark Horn and Cyber Dragon Herz effects, plus searchers that refill the hand after a board wipe
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adjust between games

Why it scores here

The deck reliably opens a searcher-driven starter on most hands: the evidence gives roughly a 92 percent chance of at least one searcher in the opening five, so the engine is usually live by turn two. Its ceiling comes from Fusion and Link finishers such as Cyberdark End Dragon and Cyber End Dragon, and its interaction is layered through about 10 hand traps and 28 removal-text cards, which is why it scores well on closing power and endboard interaction. Its weaknesses are a bloated 58-card Main Deck with 31 zero-level non-monsters, three conflicting archetype cores (Cyberdark, Cyber Dragon, and Therion, with 0 percent exact-name purity), and no Side Deck, which pulls down efficiency, brick management and recovery. No combo boards are recorded, so the floor and median are text-only inference, and the archetype's popularity and the usage data were not treated as evidence of strength. Scores are built from the deck as a system, not from averaging the card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange (meta-neutral: D13 dropped and weights renormalised over 95). Structural ≈ 56, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Engine conflicts (-4); No side deck (-3); Limited card exposure (-1); Unresolved passcode (0). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*55.7 + 0.20*45 = 53.6, then modifiers -6.6 → 47

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• High searcher density (22 cards) keeps the engine live on most hands
• Layered interaction: about 10 hand traps, 28 removal-text cards and 12 negation-text cards
• Strong Fusion and Link finishers, including Cyberdark End Dragon at 5000 ATK

Weaknesses

• Bloated Main Deck: 58 cards, 31 zero-level non-monsters and 18 singletons
• Three competing archetype cores with 0 percent exact-name purity
• No Side Deck, so no post-side adaptation
• Four of the Main Deck's 14 Extra cards (Cyber Dragon Nova, Chimeratech Megafleet Dragon, Droll and Lock Bird) are missing from the usage-standard core

Critical choke points

• Fusion and Link finishers depend on specific Cyber Dragon and Cyberdark materials that must already be on the field or in the GY
• Only one copy each of the Limited cards Harpie's Feather Duster and PSY-Framegear Gamma
• A single Quick-Effect answer from the opponent can stop an unprotected Fusion line

Recommended changes

Evidence & confidence

• Verified: Legality: 58 Main, 14 Extra, 0 Side; within the OCG size rules (40–60 Main, 0–15 Extra and Side); Limited status: Harpie's Feather Duster and PSY-Framegear Gamma, one copy each, legal; Archetype purity 0 percent exact-name; 72 off-archetype copies; Usage stats: Therion King Regulus (94.7 percent) and Harpie's Feather Duster (52.6 percent) present; Cyber Dragon Nova (63.2 percent) missing
• Inferred: P(at least one searcher in opening 5) ≈ 0.92; Full-brick and dead-card rate is elevated by 31 zero-level non-monsters and three archetype cores; Hand-trap coverage going second ≈ 0.70 at least one hand trap in six cards; Going-second strength from Raigeki, Lightning Storm, Harpie's Feather Duster and Cosmic Cyclone
• Provisional: Meta Power (no dated metagame sample); Matchup fit (D13) (no tournament link or match records)
• 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 absent One passcode (10443957) in CardIDList could not be resolved and is counted as Main No win-rate telemetry; going-first and going-second split and brick rates are Inferred Meta Power is Provisional without a dated metagame sample
