Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

• Primary strategy: Stun
• Secondary strategies: Control, Toolbox
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Negate-and-disrupt the opponent's board with hand traps and negation spells, then convert the surviving board through Fiendsmith and Link/Fusion boss monsters (Fiendsmith's Lacrima, Underworld Goddess of the Closed World, Fiendsmith's Desirae).; Live Twin / Evil Twin Link pressure (Evil Twin Lil-la, Evil Twin Ki-sikil) and Forbidden Droplet / Dark Ruler No More board-breaking.
• Turn 1 (going first): Open with Secret Password or Live Twin Sunny's Snitch to find a Live Twin monster, Normal Summon Ki-sikil or Lil-la, then Link Summon Evil Twin monsters while holding Ash Blossom and Ghost Belle as interaction.
• Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Belle, Effect Veiler, D.D. Crow, Droll and Lock Bird) to answer the opponent's first summon or search, then rebuild with Live Twin or Fiendsmith lines.
• Recovery: Fiendsmith Engraver and Fiendsmith's Tract recover LIGHT Fiend monsters from the GY; Live Twin Lil-la Sweet recurs from the GY when a Ki-sikil is on the field.
• After siding: No Side Deck is registered (side_count 0), so no post-side plan exists in this export.

Why it scores here

This list is Illegal in TCG: three Forbidden cards (Called by the Grave, Triple Tactics Talent, D/D/D Wave High King Caesar) and three Limited or Semi-Limited cards are over their copy limits (Ash Blossom x3, Fiendsmith Engraver x2, Droll and Lock Bird x2), so the score is capped at 20 and is theoretical or structural only. Structurally the deck reads as a Stun/Control shell: 19 hand-trap tagged cards and 21 negation-text cards give strong interaction density (D7 75) and a high chance of holding at least one hand trap when going second (0.93), which is what earns its points. Its engine is thin: only 2.9% of cards carry the exact 'forbidden' archetype name, 68 of 70 copies are off-archetype, and the Fiendsmith, Live Twin and Evil Twin lines are spread across 3 to 9 copies each, so starter access is roughly 0.69 for a searcher and 0.39 for the Fiendsmith core. No combos were recorded, so ceiling and median are text-only inference, and no meta or tournament data supports any matchup claim. The score comes from consistency and interaction on the list as a system, not from averaging card scores and not from archetype popularity.

Dimension scores

How the score was computed

Strategy profile: Stun. Structural ≈ 48, Going First ≈ 40, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-6); engine_conflicts_archetype_purity (-4). Final formula: Pre-cap: 0.80*Structural(48) + 0.20*TournamentReliability(35) = 45.4, then modifiers -10 -> 35.4; Illegal-deck cap applied -> 20 (theoretical/structural-only). Meta Power provisional/null.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.69 · 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

• Very high hand-trap and negation density (19 hand traps, 21 negation-text cards) gives strong going-second disruption
• Multiple independent interaction options (Ash Blossom, Ghost Belle, Effect Veiler, D.D. Crow, Solemn Judgment) cover many interruption points
• Several recursion effects (Fiendsmith Engraver, Live Twin Lil-la Sweet) help rebuild after an interruption

Weaknesses

• Illegal in TCG: Forbidden and over-limit copies must be removed before the list can be played
• Off-archetype spread: only 2.9% exact-name purity, so the engine is thin and inconsistent
• Extra Deck slot is partly dead while Caesar is Forbidden
• No Side Deck and no recorded combos or matchup data

Critical choke points

• Fiendsmith Engraver and Fiendsmith's Tract are the only LIGHT Fiend search; losing them removes the Fiendsmith core
• Live Twin Ki-sikil must be on the field to enable Lil-la and Evil Twin Link lines
