Therions Deck #758108 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 54 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Psychic End Punisher, Ukiyoe-P.U.N.K. Amazing Dragon, Divine Arsenal AA-ZEUS, Titanic Galaxy) after a Therion or P.U.N.K. engine establishes board; Recursive Therion and P.U.N.K. Level 8 beaters from the GY via Therion Lily, Noh-P.U.N.K. Rising Scale and Ogre Dance
• Turn 1 (going first): Open a Therion or P.U.N.K. starter (Lily, Discolosseum, Rising Scale, Deer Note) and convert it into a Level 8 body, then protect with hand traps (Ash Blossom, Effect Veiler, Red Reboot) held up on the opponent's turn
• Turn 2 (going second): Hand traps (Droll & Lock Bird, Maxx C, Nibiru, Ash Blossom, Effect Veiler) to stop the opponent's first board, then a Therion negation or boss from the Extra Deck
• Recovery: Therion Charge and Discolosseum draw and search Therion cards, and Endless Engine Argyro System recycles a Therion from the GY
• After siding: Not evaluable: the deck runs no Side Deck (0 cards), so there is no post-side plan

Why it scores here

The list is illegal: it runs one Forbidden card (Baronne de Fleur) and two copies of a Limited card (Droll & Lock Bird), so the final score is capped and the result is structural-only. Structurally the deck is a connected two-engine Therion and P.U.N.K. build: Therion Lily, Rising Scale and Ogre Dance start Level 8 lines, and a dense layer of hand traps and negations (Ash Blossom, Effect Veiler, Red Reboot, Maxx C, Nibiru) gives it real interaction. Its Extra Deck boss monsters carry strong ATK, and the 14-card Extra Deck covers several Summon methods. The score does not come from averaging card scores or from the archetype's popularity, which is not in the evidence. It is dragged down by the lack of a Side Deck, the engine-conflict risk of splitting Therion and P.U.N.K. across one 54-card main, and the absence of any combo or tournament data.

Dimension scores

How the score was computed

Strategy profile: Balanced (default; strategy is a Midrange/Toolbox blend). Structural ≈ 53, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 47. Modifiers: banlist_exposure (-6); no_side_deck (-4). Final formula: Illegal deck: unrounded 0.80*Structural(53.2) + 0.20*TournamentReliability(47) = 52 before modifiers; modifiers total -10 gives 42; capped at 25 for an Illegal list. Structural-only reading. Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.26 · 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 layer (12 hand traps, 8 negation-text cards)
• High-ATK Extra Deck closers across Synchro and Xyz
• Recursion and searchers (Therion Charge, Discolosseum, Argyro) reduce brick risk

Weaknesses

• Illegal list: Forbidden and over-limit cards
• No Side Deck
• Two competing engines (Therion and P.U.N.K.) in one 54-card main
• Only 0.26 chance per 3-copy engine card to be in the opening 5

Critical choke points

• Single Therion or P.U.N.K. Level 8 starter in hand, with no second independent line evidenced
• Reliance on Droll & Lock Bird, which is over its legal copy limit

Recommended changes

Evidence & confidence

• Verified: Illegal status: Baronne de Fleur Forbidden, Droll & Lock Bird over copy limit; Main 54 and Extra 14 are within OCG size rules; No Side Deck (0 cards); Usage stats: Regulus and Droll are core, Ash is a core card present at 2 copies; Hypergeometric draw odds for 3-copy cards
• Inferred: Engine consistency and brick rates; Going-first and going-second read; Interaction and board-breaking quality from card text
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (no tournament data)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot record are absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) exists in YGOVN Meta Power is provisional without a dated metagame sample Deck title is null, and no Side Deck is present
