Reptilianne Deck #57075 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Medium)

• Primary strategy: Toolbox
• Secondary strategies: Midrange
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Extra Deck boards built from Link/Synchro/Xyz (Aron, Keurse, Unchained Abomination, Saryuja, Cosmic Slicer Zer'oll) that convert an established field into attack; Reptilianne Hydra destroying 0-ATK monsters plus draw; Exodia pieces are a nominal five-piece win that is effectively unreachable
• Turn 1 (going first): Open on Upstart Goblin, Into the Void, Allure of Darkness or a Reptilianne searcher (Ramifications, Nauya) to find a Reptile starter; combine with Coatl or Lamia to reach a Link or Synchro summon
• Turn 2 (going second): Six-card hand with a searcher and a monster-based starter (Nunu, Nauya, Zohah, Coatl) to set up Ramifications ATK-zeroing and Hydra or Zer'oll board breaks
• Recovery: Recursion from the GY via Nunu, Nauya, Zohah and Aron, with Reptilianne Spawn revival tokens and Lamia as a Tuner
• After siding: Not applicable: Master Duel has no side deck and the list runs 0 side cards

Why it scores here

This list is a Reptilianne-branded Toolbox that pulls from several archetypes (Ogdoadic, Exodia, Alien, Performapal, Mathmech, Unchained) with only 9 exact-name Reptilianne cards, so its engine is weakly connected. Its searchers (8 text hits, 69% chance of at least one in a 5-card hand) and Link/Synchro/Xyz finishers give it a credible closing ceiling, which is where most of its points come from. Consistency is poor: several cards need specific conditions (Advance Draw needs a Level 8+ monster and the deck has only Aron and Keurse at Level 8), and the five Exodia pieces are dead outside a near-impossible hand. The score is also capped by legality: it runs Allure of Darkness at 3 copies against a limit of 1 and Phantasmal Lord Bishbaalkin, which is Forbidden, so this is a theoretical, structural-only read and not a normal Final Contextual score. Popularity and archetype usage were not used to add points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 40, Going First ≈ 40, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-6); hard garnet / dead-card burden (-3). Final formula: Illegal list: theoretical structural-only. 0.80*Structural(40) + 0.20*TournamentReliability(35) = 39, minus modifiers (-9) = 30. 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

• Strong closing bodies across Link, Synchro and Xyz (Unchained Abomination 3000 ATK, Saryuja 2800, Zer'oll 2600)
• Eight searcher-text cards give a reasonable chance of finding a starter
• Extra Deck coverage across three summon types

Weaknesses

• Illegal list: Allure of Darkness is over its copy limit and Bishbaalkin is Forbidden
• Off-archetype spread: only 9 exact Reptilianne cards, with the rest from unrelated sub-archetypes
• Five dead Exodia pieces and conditional draw spells reduce consistency
• No side deck and no combo data to confirm a real line

Critical choke points

• Forbidden Bishbaalkin in the Extra Deck is not legally usable and would have to be removed
• Allure of Darkness over-limit copies must be cut to one

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 are within Master Duel size rules; Allure of Darkness is 3 copies vs Limited 1; Bishbaalkin is Forbidden (0 legal copies); Composition: 9 exact-name Reptilianne cards, 46 off-archetype copies, 16.4% exact-name purity; Card stats for Aron, Keurse, Unchained Abomination, Saryuja and Zer'oll
• Inferred: Opening-hand searcher probability ~0.69 and Exodia negligible; Engine accessibility and brick risk from card text; Interaction, recursion and going-second estimates from card text
• Provisional: Meta fit and matchup coverage (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 pilot match record absent usage statistics marks Reptilianne Echidna and Reptilianne Hydra as missing core cards, but both appear in the Extra Deck card list; the usage matching appears inconsistent and was not relied on No win-rate telemetry for going-first, going-second, matchups or brick rate Meta Power is provisional without a dated metagame sample
