FIre Formation Deck #761757 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Fusion
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 8 violation(s).

Identity & game plan

• Win condition: Fusion Summon a Lunalight boss (Lunalight Liger Dancer / Panther Dancer / Sabre Dancer, 3000-3800 ATK) via Polymerization-type spells and Lunalight Fusion, backed by Lunalight searchers; Xyz and Link pressure (Primathmech Alembertian, Salamangreat Almiraj, S:P Little Knight) once the Fusion line is established
• Turn 1 (going first): Open a Lunalight searcher (Gold Leo, Scarlet Tiger, Yellow Marten) or a Fusion spell, search Polymerization/Lunalight Fusion, and Fusion Summon a Lunalight boss on T1-T2 using the Lunalight monsters in hand
• Turn 2 (going second): Use Ash Blossom / Droll & Lock Bird / Dominus Impulse to disrupt the opponent's first board, then rebuild through Lunalight searchers from the GY and Luna Light Perfume into a Fusion boss
• Recovery: Lunalight Black Sheep and Lunalight Yellow Marten recycle Lunalight monsters from the GY, Luna Light Perfume re-summons from the GY, and Lunalight Perfume Dancer returns to hand to replay
• After siding: No side deck is run (side count 0); no post-side plan is available in the evidence

Why it scores here

The Lunalight core (30 copies, about 98% chance of at least one in a 5-card opening hand) gives this list a reliable searcher density, and the Fusion bosses give it a strong closing ceiling. Consistency is held back by the mixed build: only 3 of 70 archetype copies are the exact Fire Formation name, with Mulcharmy, Dominus, Mask, Harpie, Mathmech and Salamangreat pieces diluting the engine, and 28 Level-0 spell/trap slots add brick risk. The list is Illegal under the TCG banlist: 5 Forbidden cards are present and 3 copy limits are exceeded, so the score is capped at the theoretical level rather than a normal contextual score. Popularity and archetype usage stats confirm the Lunalight core is real and accessible, but they did not earn points by themselves, and no card scores were averaged into this result.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 55.2, Going First ≈ 55, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: Structural 55.2 (Combo profile). No-meta formula 0.80*55.2 + 0.20*45 = 53.2, then -12 banlist-exposure modifier ≈ 41. Illegal list (Step 2): capped at 25 as a theoretical/structural-only score.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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

• Lunalight searcher density gives a high chance of a live starter
• Fusion bosses (Sabre, Panther, Liger Dancer) give a high closing ceiling
• Layered interaction through hand traps and negations

Weaknesses

• Illegal under the TCG banlist (copy limits and Forbidden cards)
• Engine diluted by 67 off-archetype copies from several archetypes
• No side deck, so no post-side adaptation
• High brick density from 28 Level-0 spell/trap slots

Critical choke points

• Polymerization-type Fusion enablers (4 spells total) gate most boss summons
• Lunalight Fusion needed for the 2-card bootstrap line

Recommended changes

Evidence & confidence

• Verified: Illegal status: 8 over-limit or Forbidden entries; Main 55 / Extra 15 / Side 0 counts; Lunalight core 30 copies; exact Fire Formation purity 4.3%; Extra Deck: 8 Fusion, 4 Xyz, 3 Link
• Inferred: Hand probabilities (hypergeometric); Brick risk from Level-0 spell/trap density; Going-first vs going-second plans from card text; Dimension scores based on text reads
• Provisional: Meta Power (null) and tournament-level matchup fit
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry for going-first/second, matchup, or brick/starter rates Meta Power is provisional without a dated metagame sample Data inconsistency: Brotherhood of the Fire Fist - Tiger King is listed in the Extra Deck (1 copy) but also marked as missing core (in_this_deck false)
