Therions Deck #767443 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 34/100 (±10 · Confidence: Low)

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

Legality

Main 56 / Extra 14 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Extra-Deck boss monsters (K9-X "Werewolf", K9-X "Ripper/M", Divine Arsenal AA-ZEUS, Chimeratech Rampage Dragon) backed by Cyber Dragon / K9 / Cyberdark support, with no recorded line to confirm conversion.; Hand-trap and negation-driven disruption (Ash Blossom, Infinite Impermanence, Ghost Belle, Effect Veiler, Droll & Lock Bird) that stalls the opponent while the board is built.
• Turn 1 (going first): Open with searchers (Cyber Dragon Core, Cyberdark Realm, K9-66b Lantern, Clockwork Night) to reach a Cyber Dragon or K9 Xyz route; the first Normal Summon is the main unknown because the list has no starter-specific structure beyond the shared core.
• Turn 2 (going second): Hold hand traps (19 hand-trap-tagged cards, about 93% to have one in a 6-card going-second hand per the hypergeometric estimate) to negate the opponent's first engine play, then build into an Extra-Deck boss.
• Recovery: Recover through Mulcharmy draw effects, Cyberdark Claw and Clockwork Knight recursion and the K9 Quick-Play searches; the recovery path exists in text but is not verified on any recorded board.
• After siding: Not evaluable: the deck has zero Side Deck cards, so there is no post-side plan to assess.

Why it scores here

The deck is scored as a system: it is built from several sub-archetypes (Cyber Dragon, K9, Cyberdark, Mulcharmy, Therion) with only 0 cards in the exact Therions name, so its engine coherence is limited (D1 40). Its strength is interaction, with 19 hand-trap-tagged cards and 16 negation-text cards that give a strong going-second disruption profile (D7 62, D8 60), and a searcher density that makes the core reachable (D6 55). Its weaknesses are the absence of any recorded combo (D3 and D4 rest on text inference only), the absence of a Side Deck (D12 10) and an Illegal list that puts two cards over their OCG limit. The score does not come from Therions being a popular archetype and does not come from averaging individual card scores. Because the list is Illegal, it receives no normal Final Contextual score: it is capped low and the result is structural and theoretical only.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; no secondary weight applied. Structural ≈ 47, Going First ≈ 45, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal copy-limit violation (-8); No Side Deck (-2); Multi-engine fragmentation (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Illegal list, so the result is capped low and labelled structural/theoretical only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.6 · key two-card combo ≈ — · full-brick estimate ≈ 0.4 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense hand-trap and negation suite (19 hand-trap-tagged, 16 negation-text) gives strong going-second disruption.
• Searcher density (20 searcher-text cards, about 0.90 at least one in a 5-card opener) makes the core reachable.
• Extra Deck carries high-ATK closers (K9-X Werewolf 3300, K9-X Ripper/M 3100, Divine Arsenal AA-ZEUS 3000).

Weaknesses

• Illegal list: Ash Blossom and K9-17 Izuna each over the copy limit.
• No recorded combos, so the ceiling and median are inferred from text only.
• Five sub-archetypes compete for one Main Deck, reducing engine coherence.
• No Side Deck, so there is no post-side adaptation.

Critical choke points

• Legality: the list cannot be played in the OCG format until two copies of each over-limit card are removed.
• Engine starter: the archetype-core group is only about 0.60 to appear in a 5-card opener.
• Extra Deck dependence on K9 and Cyber Dragon Xyz routes.

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring and K9-17 Izuna each run 3 copies against an OCG limit of 2.; Main 56, Extra 14, Side 0, all within the OCG size rules except the zero-card Side Deck.; Extra Deck threat stats (K9-X Werewolf 3300 ATK, K9-X Ripper/M 3100 ATK, Divine Arsenal AA-ZEUS 3000 ATK).
• Inferred: D1 engine consistency: P(at least one core copy in a 5-card opener) about 0.60.; D7 and D8 interaction and going-second strength, from hand-trap and negation text plus hypergeometric odds.; D6 searcher reach: P(at least one searcher in a 5-card opener) about 0.90.
• Provisional: Meta Power is null because no dated metagame sample exists.; D13 matchup and format fit, since no tournament link is present.; Tournament Reliability (40) rests on text inference and no win-rate telemetry.
• 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. One CardIDList passcode could not be resolved to a card (counted as Main). No win-rate telemetry (going-first/second, matchup, brick and starter rates) exists in YGOVN. Meta Power is provisional unless a dated metagame sample is supplied. Deck title is null, and there are no guides for the archetype.
