Mermail Deck #768996 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±12 · Confidence: Low)

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

Legality

Main 60 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters from the Atlantean / Mermail / Abyss- / Daedalus pools (e.g. Poseidra Abyss, Mermail Abyssgaios, Levia-Dragoon - Daedalus), reached through Atlantean and Mermail searchers and recursion from the Graveyard.; Board pressure from Atlantean Dragoons direct attacks and Level 3 or lower Sea Serpent monsters, plus Umi / Atlantis field-driven Extra Deck summons.
• Turn 1 (going first): Open on a searcher-into-engine line (Neptabyss, Mermail Abyssteus, Mermail Abysspike) and use Atlantean and Mermail searches to find a Level 7 or Xyz/Link enabler; hold Ash Blossom and Droll & Lock Bird as interaction.
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird, Dominus Impulse and The Great Gallant Bandit to interrupt the opponent's first summon or search, then convert with Mulcharmy draw effects and the Extra Deck bosses.
• Recovery: Graveyard recursion through Atlantean and Mermail monsters that send themselves to the GY for effects (Abyssrhine, Atlantean Heavy Infantry, Mermail Shadow Squad, Abysstrite), and searchers that rebuild the hand.
• After siding: Not available: the deck runs no Side Deck (side_count 0), so there is no post-side plan in this list.

Why it scores here

The deck is scored as a system, not as an average of its card scores. Its opening-hand access is decent: the searcher text group has an estimated 0.86 chance of at least one hit in a 5-card opening hand, and the archetype core group about 0.97 (Inferred). Interaction is dense on paper, with 4 hand traps and 13 negation-text cards, but the deck has no recorded boards, so the combo ceiling and median are text-only inferences and score low. The list is Illegal in OCG: Ash Blossom and Dominus Impulse are each run at 3 copies against a limit of 2, so it is capped at 35 and labelled structural-only. Popularity and archetype usage stats were not used to add points, and no tournament or meta share is attached, so Meta Power stays provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange (meta-neutral: D13 dropped and weights renormalized over 95). Structural ≈ 51, Going First ≈ 50, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); no side deck (-4). Final formula: 0.80*Structural(51) + 0.20*TournamentReliability(40) + ContextModifiers(-12) = 36.8; Illegal-list cap applied, final = 35 (theoretical/structural-only, not a normal Final Contextual score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.23 · 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 searcher text (19 cards) gives good access to the engine
• Multiple hand traps and negation text provide interaction on both turns
• Extra Deck spread across Xyz, Synchro and Link gives several bosses
• Mermail and Atlantean core is heavily represented and recognisable

Weaknesses

• Illegal in OCG: two cards over the copy limit
• Low exact-archetype purity (8%) suggests coherence depends on several sub-archetypes
• No Side Deck, so no post-side plan
• No recorded combos, so ceiling and median are unmeasured

Critical choke points

• Two-card hand traps (Ash Blossom, Droll & Lock Bird) are the main interaction and are unrecoverable once spent without a searcher or recursion
• Reliance on a Level 7 enabler and Atlantean/Mermail searches to reach the Extra Deck bosses

Recommended changes

Evidence & confidence

• Verified: Legality: 60 main, 15 extra, 0 side; Ash Blossom and Dominus Impulse over the OCG Semi-Limited limit of 2; Card text for hand traps, searchers and Extra Deck bosses taken from the evidence excerpts
• Inferred: Starter access estimates from hypergeometric values (0.86 searcher, 0.97 archetype core); Interaction density from text role hints; Going-first and going-second estimates
• Provisional: Meta Power and matchup fit (no dated meta sample or tournament link)
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta share and per-pilot record absent no win-rate telemetry; going-first, going-second and matchup signals are Inferred or Unknown no Side Deck; post-side plan cannot be assessed deck title is null
