Therions Deck #720773 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Xyz Combo, Stun
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Xyz Summon DoomZ and Power Patron boss monsters with layered interaction and equip recursion to grind through disruption and pressure the opponent.; Going-second board breaking via Branded Fusion removal and hand traps; stalling with floodgates.
• Turn 1 (going first): Open DoomZ engine core (Elara + Amalthe + Change searchers), establish 1-2 Xyz bosses (Drastrius/Graflareio) with equip protection, hold hand-trap interaction.
• Turn 2 (going second): Use hand traps (Ash Blossom, Nibiru, Droll & Lock) to disrupt setup; apply The Fallen & Virtuous for targeted removal; leverage Lightning Storm and Harpie's Feather Duster for backrow clear.
• Recovery: DoomZ Destruction and equip recursion loops enable repeated board rebuilds; Bystial line-outs (Druiswurm/Magnamhut) provide GY recursion and special-summon removal.
• After siding: No side deck present; cannot assess post-side adaptation. Assumed defensive tech inclusion (floodgates like Anti-Spell Fragrance) in side would support grind plan.

Why it scores here

This Therion/DoomZ-hybrid deck reliably opens a core engine starter (97.2% probability of ≥1 DoomZ or Power Patron searcher going first) and converts into 1-2 Xyz bosses with equip-based protection and recursion. Interaction density is moderate: two negation bosses (Drastrius, Regulus) plus 9 hand traps and 2 floodgates provide layered disruption. However, the deck lacks independent combo lines—disrupting one searcher path severely constrains the turn—and median board output is modest without combo examples. Going-second strength is respectable via Branded removal and hand-trap density, but going-first resiliency drops sharply when early interaction lands. The 55-card main + miss of key core cards (Santa Claws, Extra Deck Xyz alternatives) and zero side deck limit flexibility. Popularity and archetype inclusion stats confirm accessibility but do not elevate power score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 63, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 54. Modifiers: Deck size above standard (-2); No side deck (-3); Single choke-point dependency (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex 74, median 55, board-per-starter 2.1
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Engine accessibility: 97.2% probability of opening a functional starter (DoomZ/Power Patron core); heavy searcher redundancy.
• Hand-trap density: 9 copies across Ash Blossom, Nibiru, Droll & Lock, Dimension Shifter ensure disruptive going-second interaction.
• Equip-based recursion: DoomZ equip spell tutoring enables slow card advantage and repeated board rebuilds across turns.
• Xyz flexibility: Extra Deck ranks 4–12 support diverse summoning routes; no single mandatory boss monster.
• Interaction layering: Two negation Xyz bosses (Drastrius, Regulus) plus hand-trap suite provide multi-axis disruption.

Weaknesses

• Inconsistent median output: Main combo line Elara → Amalthe produces modest board (1-2 Xyz with 1-2 materials); no secondary independent lines documented.
• Single choke point: Disrupting the DoomZ searcher path (Called by Grave, Ash negation of activation) forces fallback to weaker Bystial/Branded lines; recovery narrow.
• Oversized main deck: 55 cards vs. 40-card standard; variance penalty reduces consistency premium despite high starter rate.
• No going-first pressure: Offensive board lacks pierce, direct damage, or OTK vector; relies on grind attrition vs. lethal conversion.
• Core card omissions: Missing Santa Claws, DoomZ XIII Over (Graflareio), DoomZ XII End (Drastrius) reduce median board quality and suggest suboptimal list construction.
• No side deck: Inability to tune post-side limits best-of-3 adaptation and matchup coverage.
• Floodgate dependency: Only 2 floodgates (Anti-Spell, Dimension Shifter) vs. format meta; insufficient proactive stun without side inclusion.

Critical choke points

• DoomZ searcher disruption: Ash Blossom negation of Elara/Amalthe effect activation, or Called by the Grave post-GY, removes primary consistency backbone.
• Equip tutor choke: DoomZ Command tutors are OPT; if the equipped Xyz is removed before tutor activation, recursion loop breaks.
• Extra Deck dependency: Xyz Summon restriction (DoomZ Raiders freezes Extra Deck to Xyz only) creates branching constraints; no fusion/synchro backup mid-combo.
• Nibiru vulnerability: The 5-Summon threshold trigger is plausible on turn 1 (Elara + searcher + Xyz Summon sequence); forces play around Tributing own board or forfeiting turn.

Evidence & confidence

• Verified: Legality: Legal status, 55-main/15-extra, all copy limits observed.; Card text: All 34 unique cards resolved with description excerpts.; Archetype core group probability: P(≥1 in 5) = 0.972 from hypergeometric calculation.; Hand-trap density: 9 copies of Ash/Nibiru/Droll/Dimension Shifter confirmed.; Extra Deck composition: 13 Xyz, 1 Synchro, 1 Fusion verified from card pool.
• Observed: Core card inclusion rate: 14 of 25 usage-statistic core cards present (56%); Santa Claws, Drastrius, Graflareio, Springans Merrymaker, Varudras absent.; Usage statistics: Therion archetype meta-share not supplied; rank-and-file inclusion % from 3 recorded sample decks only.
• Inferred: Combo ceiling (~74): DoomZ Elara → Amalthe into Rank-4/5 Xyz with equip tutor; inferred from card text sequencing.; Combo median (~55): Standard 1-Xyz board; no secondary lines; slower than ceiling but faster than bricked hand.; Full brick probability (~8%): 16 one-ofs and 6 two-ofs with Mulcharmy/Nibiru condition conflicts; 55-card inflation; hypergeometric estimate.; Interruption resilience (~58): Two independent starter paths (Elara vs. Amalthe) but single DoomZ searcher choke point; Bystial recursion narrow.; Going-first power (~63): Decent startup consistency (D1=74) + moderate interaction (D7=65) offset by modest combo median (D4=55).; Going-second power (~64): Respectable hand-trap draw rate (6-card + 9 hand-traps) and Branded removal, but no dedicated board-breaker line.; Pilotability (~54): DoomZ execution is linear (destroy-search-summon OPTs); 3-4 decision points per turn; moderate error tolerance.
• Provisional: Meta Power (null): No dated metagame sample supplied; archetype meta-share unavailable.; Matchup coverage (52): Format fit inferred from hand-trap and floodgate count; no tournament context to validate.
• Data gaps: No combos supplied in evidence.json; all combo floor/median/ceiling inferred from card text and standard DoomZ routing. Tournament link absent; no archetype meta-share, per-pilot match record, or win-rate telemetry. No side deck provided (0/15 cards); best-of-3 adaptation and post-side reliability cannot be assessed empirically. No win-rate telemetry in YGOVN; going-first/going-second, matchup-specific, and brick/starter/OTK frequency data are Inferred or Unknown. Guide evidence absent (0 guides); archetype strategy intent and pilot intent not documented. Combo examples missing; board state frequency, interaction density, and resource signatures cannot be verified from parsed boards.
