Therions Deck #769004 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 54 / Extra 16 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Link and Xyz boards (Sky Striker Ace links, R.B. links, Super Starslayer TY-PHON) built from hand-trap and searcher starts; no recorded combo supports a specific line; R.B. Ga10 and R.B. Lambda links pressuring through Sky Striker Mecha and R.B. Operation Test recursion
• Turn 1 (going first): Open a searcher or Sky Striker starter with the 0-level traps and spells as interaction; no combo steps exist in the evidence, so the sequence is an inference
• Turn 2 (going second): Hold 2 to 3 hand traps (Ash Blossom, Effect Veiler, Ghost Belle, Infinite Impermanence) against the opponent first Summon, then rebuild a link board
• Recovery: Recursion through R.B. Operation Test, Clockwork Night and the Link Monster Shepherd's Crook; viable on paper but unverified
• After siding: Not testable: the deck runs 0 side cards, so there is no post-side plan at all

Why it scores here

This list is Illegal: Ash Blossom & Joyous Spring is run 3 times against a Semi-Limited limit of 2, and the Extra Deck holds 16 cards against a maximum of 15, so the score is capped and reported as theoretical and structural only. The structural read comes from the system: 16 hand traps and 24 negation-text cards give the deck strong interaction and good going-second value (P of at least one hand trap in a 6-card hand is about 0.89), but the engines are split across R.B., Sky Striker and Therion-tagged cards, and only 4 of 21 archetype core cards are present, so the deck does not reliably open one functional plan. No recorded combos, win rates or meta share exist, so ceiling and median output cannot be measured and the score is not an average of card scores; the 0-side main deck also means no post-side adjustment. Popularity was not credited and no points come from the archetype label alone.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 42, Going First ≈ 36, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 33. Modifiers: illegal-list-cap (-12). Final formula: Illegal list: Final = Structural (42) - 12 illegal-list cap = 30; theoretical/structural only, no normal contextual score. Meta Power null (Provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.57 · 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

• 16 hand traps and 24 negation-text cards give high interaction density
• Going-second hand-trap access is about 0.89 for at least one in 6 cards
• Link-heavy Extra Deck (15 Links) with Link and Xyz boss options

Weaknesses

• Illegal list: Ash Blossom over copy limit and Extra Deck over size
• Only 4 of 21 archetype core cards present; engines split across R.B., Sky Striker and Therion tags
• 0 Side Deck cards: no post-side plan
• No combo evidence, so output cannot be measured

Critical choke points

• Starter access: P(at least one 3-copy card in opening 5) is about 0.26, so most hands rely on a single starter
• Legal fix is required before any score is trusted

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring 3 copies vs legal 2; Extra Deck 16 vs maximum 15; 0 Side Deck cards; Only 4 of 21 usage-stat core cards present
• Observed: No combos supplied (0 boards)
• Inferred: Hand-trap access on going second (about 0.89); Starter and brick probabilities (hypergeometric); Toolbox primary strategy from role tags; Interaction density read from text flags
• Provisional: Meta Power and format fit (no dated sample); Matchup coverage (D13)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent no win-rate telemetry exists in YGOVN Meta Power is Provisional without a dated metagame sample Deck title is null and the Therion archetype label does not match most of the cards, which look like Sky Striker and R.B. builds; the Cyber Dragon core of the Therion usage stats is absent
