Abyss- Deck #454682 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Stun
• 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: Large Atlantean and Mermail boards that push 2800–3000 ATK attackers such as Poseidra, the Storming Atlantean and Poseidra Abyss, the Atlantean Dragon Lord, supported by Mermail Abyssgaios and Abysstrite; Chip damage from Atlantean Dragoons, which lets Level 3 or lower Sea Serpent monsters attack directly
• Turn 1 (going first): Open a Water starter such as Mermail Abyssteus, Neptabyss or Abyssrhine, search or summon a second Atlantean or Mermail body, and hold Ash Blossom or Infinite Impermanence for the opponent's first response
• Turn 2 (going second): Use the hand traps (Ash Blossom, Infinite Impermanence, Ghost Sister & Spooky Dogwood, Artifact Lancea) to slow the opponent's first summon, then rebuild the Water board from the Graveyard
• Recovery: Recover through Mermail and Atlantean recursion from the Graveyard (Mermail Abyssteus, Atlantean Dragoons, Atlantean Heavy Infantry) and Xyz or Synchro summons from the Extra Deck
• After siding: No plan: the list has an empty Side Deck and cannot adapt after siding

Why it scores here

The score reflects the deck as a system, not an average of its card scores, and it is capped low because the list is Illegal under the TCG banlist: four Forbidden cards (Called by the Grave, two Bahamut Shark, Abyss Dweller, Trishula) are present, and Ash Blossom and Dominus Impulse are each run three times against a limit of two. The Water core is internally coherent. Atlantean and Mermail searchers and recursion, backed by ten hand traps and around twenty removal or negation effects, give it a reasonable chance of reaching a working board, and the core group is open in the opening hand in about 83% of cases. Output is hard to verify because no recorded boards exist, so median and ceiling are text-only reads and the combo dimensions are Inferred. Archetype popularity and usage data confirm the list is a real build but earn no power points, and the deck has no Side Deck, which removes any post-side adaptability.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 51, Going First ≈ 52, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-10); semi_limited_overage (-2). Final formula: 0.80*Structural(51) + 0.20*TournamentReliability(35) = 48, plus context modifiers (-12) = 36, then capped at 25 because the list is Illegal (theoretical/structural only). Meta Power is Provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Ten hand traps and about 20 removal or negation effects give repeated disruption
• Atlantean and Mermail searchers and Graveyard recursion regenerate resources
• Strong 2800–3000 ATK Extra Deck threats for closing

Weaknesses

• Illegal list: Forbidden cards and copy-limit overages
• Extra Deck slots are wasted on cards that cannot be played
• Three-copy hand traps and spells leave the opening hand exposed to bricks
• No Side Deck, so there is no post-side adaptability

Critical choke points

• Dependence on Forbidden or unplayable Extra Deck cards for the closing board
• Ash Blossom and Dominus Impulse above their legal copy limit
• No Side Deck, so matchup problems cannot be answered after siding

Recommended changes

Evidence & confidence

• Verified: Legality: the list is Illegal, with four Forbidden cards and two Semi-Limited cards over the copy limit; Card text and stats for the listed Extra Deck cards; Empty Side Deck (0 cards)
• Inferred: Consistency estimates from hypergeometric calculations on the Main Deck; Ceiling and floor reads from card text, since no recorded boards exist; Interaction and resilience reads from the removal, negation and hand-trap text
• Provisional: Meta Power (null) and matchup fit, since no dated metagame sample or tournament data exists
• Data gaps: No recorded boards, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot records are absent No win-rate telemetry exists for going-first, going-second, matchups or brick rates Meta Power is Provisional unless a dated metagame sample is supplied
