Main 40 / Extra 15 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Link-based board pressure with 3000-ATK Kaiju and Danger! attackers (Thunder King, Dogoran, Bigfoot, Borrelsword, Borreload), finished by Link monsters that negate or remove blockers; Interrupted Kaiju Slumber mass destruction into a two-Kaiju board, then a Link follow-up
- Turn 1 (going first): Open with Danger! monsters and Upstart Goblin for hand-discard-into-summon card flow, keep Ash Blossom for the first hand trap, and reach a Link Summon for board control
- Turn 2 (going second): Use Ash Blossom (x3) and Kaiju summons from the hand (tributing an opponent monster) to answer the first board, then rebuild through Danger! draws
- Recovery: Kaiju Slumber and Danger! monsters re-summon from hand and the Deck, with Upstart Goblin and Second Expedition into Danger! for draw
- After siding: No side deck is run (side 0); there is no post-side plan in the list
Why it scores here
The score comes from the system: the 40-card Main Deck runs two engines that do not share a starter, a Danger! hand-discard chain (17 Danger! monsters, P(at least one in a 5-card opening hand) ≈ 0.95, Inferred) and a Kaiju summon-by-tribute package (14 Kaiju cards), supported by 3 Ash Blossom for hand-trap answers, 3 Interrupted Kaiju Slumber for mass removal and a 15-card Link Extra Deck with negation, banish and destroy effects. Strong end-board interaction and 3000-ATK closers carry most of the score. Points are held back by the lack of combo evidence (no parseable boards, so floor, median and ceiling are text-only inference), the lack of a side deck and therefore no post-side plan, and the Danger!/Kaiju conflict (Kaiju needs an opponent's monster or an existing Kaiju on the field). The archetype label 'Kashtira' earns no credit: only 2 of 55 cards carry that name (3.6% exact-name purity), and only 2 of 10 usage-stat core cards are present, so popularity did not move the score. No card scores were averaged.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 72 | P(at least one of 17 Danger! monsters in a 5-card opening hand) ≈ 0.95; Kaiju starters need an opponent monster or an existing Kaiju (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 65 | Danger! monsters are summonable from hand, which lowers brick risk; Kaiju cards and the 14-card Kaiju/Danger split create some dead-card risk on turns with no opponent monster (Inferred) |
| D3 | Combo Conversion & Ceiling | 65 | Interrupted Kaiju Slumber, Kaiju two-Kaiju board and Link follow-ups give a high ceiling, but there are no parseable boards to check it (Inferred, semantic) |
| D4 | Combo Floor & Median Output | 52 | Median output is unknown: combos_evidence has zero boards, so the floor comes only from the Danger! hand-summon chain (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 65 | Three Ash Blossom plus multiple hand-summon routes and Kaiju Slumber recursion give several independent continuations after disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Danger! hand-discard costs a random card each turn and draws 1 back; Upstart Goblin and Second Expedition into Danger! add draw; no resource data (Inferred) |
| D7 | End-Board & Interaction Quality | 74 | Link interaction is broad: Underworld Goddess negates all face-up monsters' effects, Accesscode Talker, Worldsea Dragon Zealantis and Knightmare Cerberus remove or negate, plus 3 Ash Blossom (Inferred from card text; flags verified) |
| D8 | Going-Second & Board-Breaking Power | 70 | Interrupted Kaiju Slumber, Kaiju summons from hand and Ash Blossom answer a going-second board; the strongest 3000-ATK boards from a single summon add pressure (Inferred) |
| D9 | Offensive Pressure & Closing Power | 72 | Attackers Thunder King 3300, Radian 2800, Dogoran 3000, Borrelsword Dragon 3000 and Borreload Dragon 3000 close well if they stick (verified ATK, Inferred use) |
| D10 | Main Deck Efficiency & Flexibility | 58 | 40 Main with 20 distinct cards, and 18 Danger!, 14 Kaiju and 8 generic cards that split two engines; Upstart Goblin x3 and Ash Blossom x3 are generic (verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 15 single-copy Link monsters with mixed support: Knightmare 3, Borrel 2, Code Talker 1, P 1, and 8 with no archetype (verified composition; efficiency Inferred) |
| D12 | Side Deck Adaptability | 20 | The deck runs no side deck (side count 0 of 15 allowed) so there is no post-side adaptability (verified count; no performance data) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link and no meta-share for this list; Meta Power stays provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 50 | Multi-step Kaiju tribute summons, hand-discard decisions and Link co-link chains require careful sequencing, so error tolerance is middling (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 62, Going First ≈ 68, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 53. Modifiers: Engine conflict (-3); No post-side plan (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*62 + 0.20*53 = 60.2, then modifiers -5 = 55
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.95 · 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
- Two independent hand-based starter routes (Danger! and Kaiju) give consistent openings
- Three Ash Blossom and Link negation/removal give broad interaction
- 3000-ATK Kaiju and Dragon attackers close games quickly
- Legal list with all cards at Unlimited status
Weaknesses
- Archetype label 'Kashtira' does not match the list (2 of 55 cards)
- Danger! and Kaiju conflict in their summon conditions
- No side deck, so no post-side plan
- No combo or board data to measure floor, median or ceiling
Critical choke points
- Kaiju tribute summons need an opponent monster or an existing Kaiju on the field
- Ash Blossom is the main hand-trap answer to disruption; no secondary hand trap
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | None (the list is legal; the issue is the archetype label) | Correct the archetype label to match the list, or rebuild around the Kashtira core (Kashtira Unicorn, Kashtiratheosis, Kashtira Shangri-Ira) | Only 2 of 55 cards carry the Kashtira name, so the label and the usage-stat comparison do not describe this deck |
| 2 | None | A side deck (up to 15 cards) answering the expected matchup disruption | Side count is 0, so the deck has no post-side plan in a best-of-3 format |
Evidence & confidence
- Verified: Legal under BanMasterDuel; 40 Main, 15 Extra, 0 Side within size rules; All 35 distinct cards at Unlimited status; copy counts within limits; Composition: 18 Danger!, 14 Kaiju, 2 Kashtira, 3 Ash Blossom, 3 Upstart Goblin, 15 Link monsters; Card text and ATK/DEF values from the evidence pack
- Inferred: P(at least one Danger! monster in a 5-card opening hand) ≈ 0.95; Danger! and Kaiju engine conflict; Interaction density and board-breaking read from card text; Going-first and going-second estimates
- Provisional: Meta Power (no dated metagame sample); Matchup fit and tournament reliability
- 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 absent No win-rate telemetry for this deck No dated metagame sample: Meta Power is provisional Archetype label 'Kashtira' conflicts with the list (2 of 55 cards)
