Therions Deck #772052 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 58 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Link and Xyz boards (Traptrix Pinguicula, Traptrix Rafflesia, Sacred Tree Beast Hyperyton, Teardrop the Rikka Queen) and large Main Deck bodies (Nibiru, Therion King Regulus); no recorded board confirms any of these lines; Attrition through hand traps and Trap Holes that answer each summon or activation, leaving the opponent to rebuild
• Turn 1 (going first): Open on Traptrix and Mulcharmy starters, search with Traptrix Mantis or Myrmeleo, and hold Ash Blossom, Evenly Matched and Infinite Impermanence for the opponent's turn
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll & Lock Bird, Nibiru, Infinite Impermanence) and Trap Holes to disrupt the opponent's summons, then build a Link or Xyz board
• Recovery: Recover from the Graveyard through Traptrix and Hole text (Holeutea, Pudica, Rikka Queen Strenna add-to-hand); exact recovery lines are only partly visible in the excerpts
• After siding: No post-side plan: the Side Deck is empty (Side Deck size 0), so the deck cannot adapt between games

Why it scores here

The deck is Illegal as built: Ash Blossom & Joyous Spring is run three times against an OCG Semi-Limited limit of two, so the normal Final score is capped and this evaluation is structural-only. Structurally it is a Toolbox-style Trap Hole and hand-trap list with a Traptrix Link and Xyz top end; its strongest parts are the interaction density (21 removal-text cards and 13 hand-trap-tagged cards) and the going-second hand traps. Its weakest parts are the spread across three unrelated engines (exact-name archetype purity is 0%, with 73 off-archetype copies across Traptrix, Hole, Mulcharmy, Rikka and others), 17 tech and 13 hand-trap slots that create dead cards, and a zero-card Side Deck. There are no recorded boards and no usage-based win data, so no combo ceiling or floor was measured and the scores rest on card text and hypergeometric estimates. Popularity was not credited, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary; Stun not blended into the weights. Structural ≈ 47.5, Going First ≈ 45, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-6); no side deck (-4). Final formula: Illegal cap: min(30, 0.80*Structural + 0.20*TournamentReliability + ContextModifiers) = min(30, 0.80*47.5 + 0.20*40 - 10) = min(30, 36) = 30 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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 interaction: 21 removal-text cards and 13 hand-trap-tagged cards
• Going-second hand-trap coverage: about 0.80 chance of at least one hand trap in a 6-card hand
• Multiple Link and Xyz closers available from the Extra Deck

Weaknesses

• Illegal as built: Ash Blossom & Joyous Spring is over its copy limit
• Three engines without a shared core (exact-name archetype purity 0%)
• Zero-card Side Deck gives no post-side adaptation
• High tech and hand-trap count raises dead-card risk

Critical choke points

• Ash Blossom & Joyous Spring copy count (must be cut to 2 to be legal)
• Starter access: only about a 24% chance of any single 3-copy starter in a 5-card opening hand
• Side Deck absent, so the matchup plan has no adjustment

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Ash Blossom & Joyous Spring 3 copies vs OCG Semi-Limited limit of 2; Main Deck 58 and Extra Deck 15 are within the OCG size rules; Droll & Lock Bird, Harpie's Feather Duster and S:P Little Knight are each run once (Limited); Side Deck is empty (Side Deck size 0); Usage stats show 3 of 5 core cards present
• Inferred: Starter access probabilities (hypergeometric); Brick rate and dead-card estimates; Interaction density from text roles; Going-second hand-trap coverage
• Provisional: Meta Power (null, no dated metagame sample); Format fit (no tournament link)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta share and per-pilot match record absent No win-rate telemetry: going-first and going-second win rates, matchup results and brick rates are unknown Meta Power is provisional without a dated metagame sample Several card excerpts are truncated, so some recovery text is only partly visible
