Triamids Deck #61075 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±10 · Confidence: Low)

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

Legality

Main 44 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Triamid boss monsters (Triamid Sphinx, Triamid Master, Triamid Hunter) pushed through field-spell buffs; the Extra Deck Fusion bosses have no verified summon route in the main deck.; Five-Headed Dragon and Dinowrestler Chimera T Wrextle as late-game Fusion finishers if the Extra Deck can be reached.
• Turn 1 (going first): Open a Field Spell (Triamid Fortress, Cruiser or Kingolem) with Triamid Loading or Terraforming, then Normal Summon Triamid Master or Dancer and use the field's Rock-type stat boost to build a board.
• Turn 2 (going second): Hold Infinite Impermanence or Evenly Matched for the opponent's first board, then re-establish through Triamid Pulse and Triamid Sphinx special summons.
• Recovery: Field Spells and Triamid cards return to hand or Deck from the Graveyard (Fortress, Cruiser, Kingolem, Pulse banish costs), so most disruption can be re-threaded into a new Field Spell.
• After siding: No side deck is registered, so there is no post-side plan.

Why it scores here

The score comes from the system: nine Field Spell copies and the Triamid searchers give a reasonable chance of a live engine by turn two, and the Field Spells' recursion from the Graveyard keeps the deck running after disruption. Interaction is layered across hand traps, Harpie's Feather Duster, Dark Ruler No More, and Triamid Pulse, which helps the deck stay in the game, and the Triamid bosses give it a credible board. Heavy penalties come from the illegal list (three copies of Pot of Extravagance and two of Called by the Grave, which is Forbidden), the 15-card Extra Deck with no verified Fusion route in the main deck, and an empty side deck. The result is a structural-only read with a capped final score, since no recorded boards, tournament data, or dated meta sample exist for this list. Popularity and archetype usage were not credited; card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; D13 excluded and weights renormalised over 95 (meta-neutral). Structural ≈ 54, Going First ≈ 58, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist and copy-limit exposure (-8); Extra Deck access gap (-4). Final formula: Illegal list: structural-only, capped. Structural 54.2 (meta-neutral) with 0.80*Structural + 0.20*TournamentReliability = 52.4, then context modifiers of -12 give 40

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.7 · 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

• Nine Field Spell copies plus Triamid searchers make the engine live often
• Layered recursion from the Graveyard keeps the deck going after disruption
• Strong Triamid bosses and high-ATK Fusion finishers in the Extra Deck
• Interaction from hand traps, Harpie's Feather Duster and Dark Ruler No More

Weaknesses

• Illegal copy counts for Pot of Extravagance and Called by the Grave
• Extra Deck of 15 Fusion monsters has no verified summon route in the main deck
• No side deck, so no best-of-3 adaptation
• Dead or near-dead cards (Called by the Grave, Pot of Extravagance) reduce consistency

Critical choke points

• A single Field Spell on the field; if it is destroyed or negated, the Triamid board loses its buff and must re-thread
• Extra Deck access is unproven, so the Fusion bosses may never be reached

Recommended changes

Evidence & confidence

• Verified: Illegal status: Pot of Extravagance 3 copies vs limit 2; Called by the Grave 2 copies vs Forbidden; Main deck 44 cards, Extra Deck 15 cards, Side deck 0 cards; Card text and stats for each listed card
• Inferred: Field Spell access about 0.70 in a 5-card opening hand (hypergeometric); Consistency, recovery and interaction scores from card text; Extra Deck access gap from the absence of a visible Fusion route
• Provisional: Meta Power and the matchup dimension (no dated meta sample)
• Data gaps: No recorded boards, so the 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 for this deck Meta Power is provisional without a dated metagame sample No deck title or side deck supplied
