Danger! Deck #774220 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±6 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Danger! and Kaiju monsters go on board from hand and the Kaiju tribute summons (Thunder King, Radian, Dogoran, Gameciel) produce large attack bodies that pressure the opponent.; Link Monsters from the Extra Deck (Knightmare, Borrel, Code Talker and generic links) add board presence once the Main Deck engine has materials.
• Turn 1 (going first): Open with a Danger! monster or Kaiju monster in hand (about 95% for at least one Danger! monster in a 5-card hand, Inferred), summon it, draw with its reveal effect, and build toward a Kaiju tribute summon or a link.
• Turn 2 (going second): Use the six-card hand to find a Danger! monster (about 97%, Inferred), hold Ash Blossom for a responsive negate, and summon a Kaiju over the opponent's monster by tributing it.
• Recovery: Upstart Goblin, Second Expedition into Danger!, and Kaiju Capture Mission draw cards, and Danger! monsters returning to hand through the reveal effect rebuild the engine from the hand.
• After siding: No Side Deck is registered (Side Deck size 0), so there is no post-side plan.

Why it scores here

The deck is scored as a system, not as an average of its card scores. Its main consistency asset is the 17-monster Danger! family, which gives about a 95% chance of at least one Danger! monster in the going-first opening hand (Inferred, hypergeometric), so the engine is usually accessible. Three Ash Blossom and the Kaiju tribute summons provide interaction and large attack bodies, but no recorded boards exist, so the ceiling and median are text-only inferences and are scored conservatively. The Extra Deck is a 15-link toolbox where 14 of 15 links have no Danger! link synergy, which lowers Extra Deck efficiency, and there is no Side Deck, which lowers adaptability. Archetype popularity and usage statistics confirm the list is real and accessible but were not counted as power. Meta Power is provisional because no dated metagame sample was supplied.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 61.7, Going First ≈ 66, Going Second ≈ 63, Meta = provisional, Tournament Reliability ≈ 54. Modifiers: engine conflict (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• 17 Danger! monsters give redundant hand-based starters, with about a 95% chance of at least one in the opener (Inferred).
• Three Ash Blossom and Kaiju tribute summons give layered interaction and board presence.
• Compact 40-card main with 20 distinct cards and a legal list in Master Duel (Verified).

Weaknesses

• No Side Deck (Side Deck size 0), so there is no post-side adaptation.
• 14 of 15 Extra Deck links have no Danger! link synergy, so the Extra Deck is largely a generic toolbox.
• Two engines (Danger! hand-reveal and Kaiju tribute summons) compete for the same hand space.

Critical choke points

• Danger! hand engine depends on the monster being in hand, so hand disruption before the opener is costly (Inferred).
• Kaiju tribute summons need an opponent monster to tribute, so the Kaiju line has no board-independent path (Inferred).

Recommended changes

Evidence & confidence

• Verified: Main Deck is 40 cards, Extra Deck is 15 cards, Side Deck is 0 (legality).; All 40 Main Deck and 15 Extra Deck cards are Unlimited in Master Duel (banlist).; Copy histogram 6x1, 8x2, 6x3 (composition).
• Inferred: P(at least one Danger! monster in going-first opener) ≈ 0.95.; P(at least one Danger! or Kaiju monster in going-first opener) ≈ 0.995.; Interaction density and brick risk from card text.
• Provisional: Meta Power (no dated metagame sample).; Matchup and format fit (no 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 match record are absent. No win-rate telemetry (going first/second, matchup, brick or starter rates). Usage statistics mark 14 Extra Deck links as in this deck:false even though cards[] lists them with copies 1; core-card presence (44) is unreliable for the Extra Deck and was not used. Deck title is null. No Side Deck is registered.
