Therions Deck #768333 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Springans Xyz boards (Gung-Ho! Springans!, Gigantic Sargas, Springans Merrymaker) and 3000-ATK Albaz Dragon fusions (The Dragon that Devours the Dogma, Mirrorjade) once a Fallen of Albaz starter is live; Divine Arsenal AA-ZEUS and Time Thief Redoer as late-game Xyz boards
• Turn 1 (going first): Open a Springans or Fallen of Albaz starter, use the Springans searchers (Tally-ho!, Springans Watch, Springans Kitt) to fetch Gold Golgonda or a Springans Xyz, and build a board while holding hand traps (Ash Blossom, Ghost Ogre, Droll) for the opponent's first activation
• Turn 2 (going second): Use a hand trap (Ash Blossom, Ghost Ogre & Snow Rabbit, Droll & Lock Bird, Infinite Impermanence) to disrupt the opponent's first board, then rebuild with Mulcharmy draw effects and Ecclesia/Springans searchers
• Recovery: Recover through Mulcharmy Fuwalos and Purulia draw effects, Springans Booty and Rockey searches, and Springans Brothers recursion from the GY; the Xyz material chain acts as a long-round resource loop
• After siding: Not evaluable: the deck runs zero Side Deck cards, so there is no post-side plan at all

Why it scores here

This list is illegal as built: Ash Blossom & Joyous Spring and The Fallen & The Virtuous are each run three times against an OCG limit of two, so under the rubric it receives a capped, structural-only score and not a normal Final Contextual score. The 55-card main is mostly generic hand traps and tech cards (13 hand-trap and 16 tech-tagged cards), and its real engine is closer to Springans than to the Therions label, since only one Therion card is present while 19 cards are Springans and 6 are Mulcharmy. Consistency is weak: the three-copy starters have only about a 25% chance of appearing in the opening five, the archetype core has about a 32% chance, and the deck has no side deck, so it has no post-side plan. Its strongest feature is end-board interaction (D7), since the hand-trap and Solemn suite can answer many openings, but this does not make it a strong system. Popularity and archetype label did not earn points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary with Midrange as secondary; no formal blend applied. Structural ≈ 41, Going First ≈ 35, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: engine conflicts (-5); no side deck (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*41 + 0.20*30 = 38.8; modifiers -9 gives 29.8; capped at 25 because the deck is Illegal (copy-limit violations)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 (13 hand traps, Ash Blossom, Ghost Ogre, Droll, Solemn x2) that answers many openings
• Several strong Extra-Deck closers at 3000 ATK and Xyz boards that can break a board
• Compact 55-card main with a legal 15-card Extra Deck

Weaknesses

• Two copy-limit violations make the list illegal as built
• Engine is split across Springans, Mulcharmy, Branded, and Dogmatika, with only one Therion card despite the archetype label
• Zero Side Deck cards, leaving no post-side plan
• No recorded combos or usage-core cards (2 of 21 core cards present), so consistency rests on inference

Critical choke points

• Springans searchers (Tally-ho!, Springans Watch, Springans Kitt) carry most of the early plan, and the 3-copy starters have about 25% opening-hand odds
• Fallen of Albaz is a single-copy starter for the Albaz Dragon fusions, and its Fusion access depends on Branded and Dogmatika cards

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom & Joyous Spring and The Fallen & The Virtuous are over the OCG copy limit; Main 55, Extra 15, Side 0; Extra breakdown 10 Xyz, 4 Fusion, 1 Synchro; Archetype spread: 26 generic, 19 Springans, 6 Mulcharmy, 4 Branded, 3 Albaz Dragon, 3 Egyptian God, 3 Solemn, 1 Therion
• Inferred: Starter and core-card hypergeometric probabilities (0.25 for a 3-copy card in hand 5, 0.82 hand-trap in hand 6); Interaction density and resilience read from card text; Going-first and going-second power estimates
• Provisional: Meta power (null); Matchup and format fit (D13)
• Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and pilot record are absent No win-rate telemetry exists in YGOVN, so going-first/second and matchup signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null and the archetype label (Therions) does not match the composition
