Therions Deck #769870 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 45/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Xyz pressure from Springans and DoomZ Xyz monsters (Gigantic Sargas, DoomZ XIII Over, Jupiter, Utopic Draco) backed by searcher-driven card advantage; Kaiju tribute summons (Dogoran, Kumongous) for board pressure, plus Raigeki as a one-card board wipe
• Turn 1 (going first): Springans or DoomZ starter (Booty, Kitt, Watch, Goblindbergh, Rockey) searches a Springans or DoomZ bridge, then Xyz Summons off a Level 4 pair (Gung-Ho, Merrymaker, Exblowrer) or the Golgonda Field Spell
• Turn 2 (going second): Raigeki or Night Beam to clear the board, then a Kaiju or DoomZ follow-up from hand; relies on the hand, with no sided interaction
• Recovery: GY recursion from Springans Brothers, Rockey and Kitt, plus DoomZ Change and Springans Watch to rebuild a starter
• After siding: None: the list runs 0 side cards, so no post-side plan exists in an OCG format that allows up to 15

Why it scores here

The deck does not follow its Therions label: it has one Therion card and 55 copies from Springans, DoomZ, Kaiju, Gagaga, Utopia, Lswarm, @Ignister and Power Patron, and the archetype's usage core is present in only 1 of 21 standard cards (4.8%). Its consistency rests on 13 searchers, which give about an 88% chance of at least one in a 5-card opening hand (Inferred), while each individual 3-copy starter has only about a 34% chance of appearing in that hand. Its ceiling comes from Xyz finishers such as Gigantic Sargas and Jupiter, but no recorded boards exist, so conversion and median output are text-based inference only. Interaction is comparatively strong (14 removal-text cards, Raigeki, Night Beam, Twister and two negation effects), but it has no hand traps and no post-side plan, and the two Sprind Fusions need Fallen of Albaz, which is absent from the list. Popularity was not used as evidence, and the score was built from system-level consistency, interaction and conversion, not by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: 80% Midrange / 20% Toolbox. Structural ≈ 53.4, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: engine conflicts (-3); no side deck (-2); dead or conditional Extra cards (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; 0.80*53.4 + 0.20*45 - 7 = 44.7 -> 45)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Legal OCG list: 40 main and 15 extra within limits, all copies Unlimited, no restricted cards
• 13 searchers give high access to a starter in opening hands (Inferred)
• 14 removal-text cards plus Raigeki and Night Beam give broad interaction (Inferred quality)
• Multiple independent engine families provide alternative routes after disruption (Inferred)

Weaknesses

• Only 0% exact archetype purity; the Therions label does not describe this deck (Verified)
• Sprind x2 cannot be summoned without Fallen of Albaz, which is absent from the list (Verified text)
• Jupiter needs 3 equips on one monster, a conditional route with few equip sources (Inferred)
• No side deck and no hand traps, so no post-side or proactive interaction (Verified)

Critical choke points

• Single-copy Gung-Ho! Springans! and Gigantic Sargas are the Springans Xyz engine: losing them removes the main closing route (Verified count, Inferred impact)
• Gold Golgonda (1 copy) is needed for the Springans Xyz search and Special Summon effects (Verified text, Inferred impact)

Recommended changes

Evidence & confidence

• Verified: Legal OCG list: 40 main, 15 extra, 0 side; all copies Unlimited (BanList field, no restricted cards); Sprind the Irondash Dragon needs Fallen of Albaz, which is not in the list (card text); Archetype usage core: 1 of 21 standard cards present (4.8%); 13 searcher-text cards, 14 removal-text cards, 3 negation-text cards, 0 hand traps
• Inferred: Going-first and going-second estimates are derived from starter density and interaction text, not recorded games; Engine conflict and Jupiter equip-stacking estimates from card text; Median and floor scoring from starter density; no recorded boards
• Provisional: Meta Power is null; D13 format fit is Provisional without a dated metagame sample
• 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 (going-first, going-second, matchup, brick and starter rates) No guides for the archetype (0 attached) Deck title is null
