Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Negate opponent effects and lock board with floodgate; Search and recycle Rock/Earth monsters for incremental advantage
- Turn 1 (going first): Open with hand traps (Ash Blossom, etc.) and Koa'ki Meiru Guardian tribute negate, then set up Barrier Statue of the Drought or floodgate effects.
- Turn 2 (going second): Use six‑card hand to disrupt with hand traps, floodgate, and search for key Rock monsters before opponent establishes board.
- Recovery: Recover resources via Rock Band Xenoguitar, Revival Golem, and Gallant Granite to refill hand and field.
- After siding: No side deck; relies on in‑deck recursion and flexible extra‑deck summons.
Why it scores here
The deck reliably opens with multiple hand traps and a tribute‑negate from Koa'ki Meiru Guardian, giving it decent early disruption. Its many searchers and rock‑focused recursion provide some resilience after disruption, but the lack of a clear combo line and heavy reliance on high‑cost summons keep its ceiling low. Brick risk is elevated by overlapping special‑summon effects and the illegal card violations, limiting consistency. Interaction quality is moderate thanks to numerous negates and a floodgate, yet offensive pressure remains weak without strong beatsticks. Overall the system is functional but fragile, reflected in the low final score.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 55 | P(≥1 core starter in 5) ≈ 0.34 (Inferred) based on hypergeometric odds for three‑copy core cards. |
| D2 | Opening-Hand Quality & Brick Management | 40 | High copy histogram and overlapping special‑summon effects suggest a notable brick risk (Inferred). |
| D3 | Combo Conversion & Ceiling | 30 | No recorded combo boards; ceiling limited to hand‑trap and search loops (Inferred). |
| D4 | Combo Floor & Median Output | 30 | Median output inferred from lack of combo evidence, typical of a control‑toolbox deck (Inferred). |
| D5 | Interruption Resilience & Route Redundancy | 55 | Multiple hand traps (Ash Blossom, etc.) and floodgate provide redundancy after disruption (Inferred). |
| D6 | Resource Economy, Recovery & Grind | 50 | Searchers (Rock Band Xenoguitar, Revival Golem) offset costly summons, but overall resource cost is moderate (Inferred). |
| D7 | End-Board & Interaction Quality | 55 | Negation text on Koa'ki Meiru Guardian, Barrier Blocker, and several extra‑deck monsters give decent interaction (Verified). |
| D8 | Going-Second & Board-Breaking Power | 45 | Hand‑trap density (p≥1 in 6 ≈ 0.39) offers going‑second pressure, but no strong board‑breaker (Inferred). |
| D9 | Offensive Pressure & Closing Power | 30 | End‑board consists of low‑ATK monsters; no high‑damage beatsticks recorded (Inferred). |
| D10 | Main Deck Efficiency & Flexibility | 35 | Archetype purity only 9.1% and many off‑archetype cards increase garnet burden (Inferred). |
| D11 | Extra Deck Efficiency & Coverage | 40 | Extra deck filled with generic synchro/link/xyz monsters, limited synergy (Inferred). |
| D12 | Side Deck Adaptability | 0 | Side deck count is zero; no post‑side adaptability (Verified). |
| D13 | Matchup Coverage & Format Fit | 30 | Tournament context unavailable; matchup fit inferred as low (Provisional). |
| D14 | Pilotability & Error Tolerance | 30 | Complex multi‑step special summons and many decision points lower pilotability (Inferred). |
How the score was computed
Strategy profile: Control. Structural ≈ 42, Going First ≈ 35, Going Second ≈ 30, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal deck penalty (-15). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) minus illegal penalty
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.34 · 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 hand‑trap suite and multiple negates.
- Search and recursion engines (Rock Band Xenoguitar, Revival Golem).
- Floodgate (Barrier Statue of the Drought) limits opponent summons.
Weaknesses
- Illegal list (over‑copy and Forbidden card).
- Low archetype purity and high garnet risk.
- No clear combo line; offensive pressure weak.
Critical choke points
- Reliance on Koa'ki Meiru Guardian tribute for key negation.
- Presence of Forbidden Number 41 prevents legal play.
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Number 41: Bagooska the Terribly Tired Tapir | Legal alternative XYZ like Number 39: Utopia | Forbidden card makes the deck illegal. |
| 2 | One copy of Called by the Grave | Another searcher or hand trap (e.g., Infinite Impermanence) | Limited copy exceeded; reduces consistency. |
Evidence & confidence
- Verified: Card text for Koa'ki Meiru Guardian, Barrier Blocker, etc.; Side deck count zero
- Inferred: Hypergeometric probabilities for starter access and hand trap density.; Brick risk from copy histogram and overlapping effects.; Resource economy from searcher counts.; Interaction quality from negation tags.
- Provisional: Matchup coverage due to missing tournament data.
- Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
