Gren Maju Deck #66657 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

• Primary strategy: Blind-Second/OTK
• Secondary strategies: Toolbox, Midrange
• Format: master-duel

Legality

Main 47 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Gren Maju Da Eiza banishes cards to power up its ATK/DEF, and Kaiju and Danger! monsters apply 3000-ATK pressure for a fast one-turn kill.; Extra Deck Xyz, Link and Synchro monsters (Galaxy-Eyes, Number, Dharc) provide a board-based finish if the Kaiju line stalls.
• Turn 1 (going first): Open with Gren Maju Da Eiza or a searcher, then Special Summon a Kaiju from the hand or Deck for a 3000-ATK board; hold Ash Blossom or Maxx "C" as hand traps.
• Turn 2 (going second): Use hand traps (Ash Blossom, D.D. Crow, Maxx "C") to break the opponent's first combo, then Kaiju Special Summons to contest the board.
• Recovery: Recover through Pot of Desires, Trade-In and Danger! monsters that Special Summon themselves from the hand, plus the banished-card resource from Gren Maju Da Eiza.
• After siding: No Side Deck is registered, so there is no post-side plan to evaluate.

Why it scores here

The deck's Gren Maju Da Eiza starter is live in the opening five only about 29% of the time and in the opening six about 34% (3 copies, 47-card Main Deck), so consistency is the first limit and it is an Inferred estimate. The Kaiju and Danger! 3000-ATK monsters and the hand-trap suite give it real pressure and disruption when the line does come online, which supports the Blind-Second/OTK read. Only 3 of the 22 distinct Main Deck cards are on the Maju or Gren Maju name, and 62 copies are off-archetype, so the list is a scattered toolbox rather than a coherent engine. There are no recorded boards for this list, so the floor and median are estimated from card text and are Inferred. The score comes from consistency, the system's interaction density and the going-second plan, not from averaging card scores or from the archetype's popularity. Because three cards are over their Master Duel copy limits (including a Forbidden card), the list is Illegal and the score is capped at 25 as a structural-only read.

Dimension scores

How the score was computed

Strategy profile: Blind-Second / OTK. Structural ≈ 41, Going First ≈ 33, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist exposure (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*41 + 0.20*30 - 4 ≈ 35; capped at 25 because the deck is Illegal (theoretical/structural-only read)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.29 · 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

• Kaiju and Danger! 3000-ATK bosses give fast board presence
• Seven hand traps plus broad removal text give disruption on both turns
• Pot of Desires and Trade-In supply card draw

Weaknesses

• Starter live only about 29% of openings (Inferred)
• Most Main Deck copies are off-archetype, so the engine is not cohesive
• Three cards over Master Duel copy limits, one Forbidden, so the list cannot be played as built

Critical choke points

• Gren Maju Da Eiza is the only true starter with three copies; without it the Maju line does not start
• Kaiju summons depend on the opponent controlling a Kaiju or a monster to tribute

Recommended changes

Evidence & confidence

• Verified: Main Deck 47 and Extra Deck 15 are within Master Duel size rules; Called by the Grave is Forbidden and is run twice; Maxx "C" is run three times against a limit of one, and Allure of Darkness twice against one; Card text for Gren Maju Da Eiza, Kaiju and Danger! monsters and the hand traps
• Inferred: Starter live probability ≈ 0.29 going first and ≈ 0.34 going second; Blind-Second/OTK strategy read from card text and the archetype guide; Kaiju pressure and hand-trap disruption as the main system strengths
• Provisional: Meta power (no dated metagame sample); Matchup fit and tournament reliability (no tournament or meta data)
• Data gaps: no recorded boards, so combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot match record absent no Side Deck registered, so post-side adaptability cannot be assessed usage statistics core list names Artmage, Mitsurugi and Power Patron cards, which do not match this Gren Maju build, so the core-card read is unusable no win-rate telemetry exists in YGOVN; all consistency and matchup claims are Inferred Meta Power is provisional unless a dated metagame sample is supplied
