Therions Deck #761222 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 57 / Extra 15 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: No recorded combos. Closing threats are the high-ATK Machine/LIGHT bodies (ABC-Dragon Buster, XYZ-Hyper Dragon Cannon, Therion King Regulus, Nibiru, Underworld Goddess), reached through Union and Fusion lines (Inferred from card text).; Hand-trap and removal attrition (Ash Blossom, Droll, Solemn Judgment/Warning, Harpie's Feather Duster, Lightning Storm) to strip the opponent's board before the Extra Deck threats land.
• Turn 1 (going first): Search or draw a Union/ABC starter (Union Hangar, Union Activation, X-Cross Cannon, Therion Discolosseum) and build toward a Fusion or Link monster. Hold hand traps for the opponent's first extender.
• Turn 2 (going second): Hand traps (Ash Blossom, Droll, Infinite Impermanence, Evenly Matched, Nibiru) to answer the opponent's first summon, then continue into the Extra Deck threats.
• Recovery: Union monsters recur from the GY through their equip and Special Summon effects (Inferred). Hand traps and Union recursion can rebuild a board after disruption.
• After siding: Not applicable. The deck has 0 side cards and no post-side plan can be read from the evidence.

Why it scores here

The deck is Illegal in OCG: it runs 3 Ash Blossom (limit 2), 2 Droll & Lock Bird (limit 1), and one copy each of the Forbidden Called by the Grave and Triple Tactics Talent, so it is capped to a structural-only read. Structurally it is a hand-trap-heavy Toolbox list that spreads across several sub-archetypes (ABC, A-to-Z, PSY-Frame, Solemn, Machina, Greed) with only three Therion cards, so its engine is diffuse rather than coherent. Its interaction density is high (about 14 hand traps and 18 negation-text cards), and the end-board removal suite is strong, which is the main source of its structural score. There are no recorded combos, so the floor, median and ceiling are text-only inferences and the closing power is Inferred from card text. Popularity and archetype label did not earn points, and card scores were not averaged into the deck score. The 0 side deck and the Illegal status keep the score low.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 46, Going First ≈ 50, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-10); no_side_deck (-2). Final formula: Illegal cap applied: base 0.80*46 + 0.20*40 = 44.8, plus modifiers -12 = 32.8, capped to 30 (structural-only, not a normal Final Contextual score); Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.63 · 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

• Dense hand-trap and negation suite (about 14 hand traps, 18 negation-text cards).
• Layered end-board removal (Lightning Storm, Harpie's Feather Duster, Solemn Judgment, Dominus Purge).
• High-ATK Extra Deck closers available across several Fusion and Xyz lines.

Weaknesses

• Illegal list: copy-limit violations and two Forbidden cards.
• Diffuse engine across six sub-archetypes; only three Therion cards.
• No side deck, so no post-side adaptation.
• Heavy tech density (23 single-copy slots) raises brick and dead-card risk.

Critical choke points

• Union and Fusion starter access depends on a small number of Union Hangar, Union Activation and X-Cross Cannon draws.
• Legality: the Forbidden and copy-limit violations must be removed before any normal rating applies.
