Identity & game plan

Win condition: Xyz beatdown and removal-backed pressure from Rikka Queen Strenna, Kanzashi, Teardrop, Alsei and Number 87 on a Plant-based board.; Number 50 and Baromet as Xyz follow-up, with Tytannial and Sacred Tree Beast, Hyperyton as extra bosses.
Turn 1 (going first): Turn 1 Rikka Glamour or Mudan the Rikka Fairy (Tribute a Plant to Special Summon), then Rikka Petal or Rikka Konkon to set up a Plant board and Xyz Summon Strenna or Kanzashi.
Turn 2 (going second): Hold Evenly Matched, Nibiru, Rikka Princess and Rose Archer for the opponent's turn, use Pollinosis, Aoi and Raigeki/Cosmic Cyclone to clear interaction, then rebuild through Plant recursion.
Recovery: Recover Plant monsters from the GY through Rikka Petal, Princess Dracaena, Primula, Carrotweight Champion and Rose Lover, then re-enter Xyz boss monsters.
After siding: No side deck is registered, so there is no documented post-side plan; the deck cannot adjust between games.

Why it scores here

The deck is scored as a system, not as an average of its cards. Its Plant-based engine (Mudan, Rikka Petal, Rikka Glamour, Rikka Konkon, Princess) has a 0.61 chance of at least one searcher in an opening five-card hand, and the 24 Rikka-core copies make a live starter likely by turn 2 (Inferred). The Xyz Extra Deck is consistent: all 15 Extra slots are Xyz, and Rikka Queen Strenna (x3) gives repeatable Plant recovery. Interaction is dense and layered, with about 13 negation and 20 removal text hits across traps, hand traps and spells, which is the main reason D7 scores well (Inferred). Popularity and archetype usage do not earn points: the 37% exact-name archetype purity and 44 off-archetype copies, plus the empty Side Deck, cap the score. No combos were recorded, so the ceiling and median stay text-inferred and the confidence is only Medium.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	66	P(at least one 3-copy starter in a 5-card opening hand) = 0.25 per card; P(at least one searcher) = 0.61; archetype core group P(at least one) = 0.95 (Inferred)
D2	Opening-Hand Quality & Brick Management	55	26 of 55 main cards are non-monsters and 12 cards carry 1-copy or Plant-tribute conditions, so some hands are dead or conflicting (Inferred)
D3	Combo Conversion & Ceiling	58	No recorded boards (combos_evidence total_combos = 0); ceiling read from text of Strenna, Kanzashi and Teardrop recursion and Tribute lines (Inferred)
D4	Combo Floor & Median Output	52	No recorded boards, so no median power index or distribution; estimated from starter diversity across Plant monsters and spells (Inferred)
D5	Interruption Resilience & Route Redundancy	66	Multiple independent Plant starters (Petal, Dracaena, Primula, Carrotweight, Rose Lover) and GY recursion give several routes after disruption (Inferred)
D6	Resource Economy, Recovery & Grind	68	Searchers and GY recursion are plentiful (9 searcher-text copies); Xyz material reuse via Strenna and Kanzashi adds resource efficiency (Inferred)
D7	End-Board & Interaction Quality	74	13 negation-text and 20 removal-text hits, plus Evenly Matched, Pollinosis, Tytannial and Nibiru as interaction layers (Inferred)
D8	Going-Second & Board-Breaking Power	66	Raigeki, Cosmic Cyclone, Forbidden Chalice and Evenly Matched challenge an established board on the second turn; no going-second split recorded (Inferred)
D9	Offensive Pressure & Closing Power	68	Boss ATK: Queen of the Night 3200, Tytannial 2800, Teardrop 2800, Orea 2800, Hyperyton 2600; 2 to 3 bosses reachable through Xyz lines (Inferred)
D10	Main Deck Efficiency & Flexibility	60	55 main cards with 25 distinct; 48 cards run at 2 or 3 copies, but 44 off-archetype copies dilute the core (Inferred)
D11	Extra Deck Efficiency & Coverage	70	All 15 Extra slots are Xyz (9 distinct); Strenna x3 gives repeatable access and the rest are one-to-two-copy finishers (Observed)
D12	Side Deck Adaptability	22	Side Deck is empty (side_count 0), so there is no post-side plan and no adaptation between games (Verified)
D13	Matchup Coverage & Format Fit	50	No dated metagame sample or tournament link; archetype share unavailable (Provisional)
D14	Pilotability & Error Tolerance	50	Many Tribute, Plant-restriction and multi-step Xyz lines with frequent decision points; repeatable with practice (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 61, Going First ≈ 64, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: engine conflicts across sub-archetypes (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability - 2 (no reliable metagame; Meta provisional)

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.25 · 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

Compact Plant engine with several independent starters and GY recursion routes
Dense, layered interaction across traps, hand traps and spells
Single-type Xyz Extra Deck with repeatable Strenna access
Boss ATK of 2600 to 3200 with several reachable Xyz bosses

Weaknesses

No side deck: no post-side adaptation
26 non-monster cards and 1-copy Plant conditions raise the brick risk
Off-archetype copies (Mulcharmy, Rose Dragon, Forbidden, Sylvan) dilute engine coherence
No recorded boards, so the combo ceiling and median are unverified

Critical choke points

Opening hand needs a Plant monster and a Tribute route; a hand without one is largely dead
Rikka Queen Strenna and Kanzashi are the main Xyz routes; losing both removes the main boss plan

Recommended changes

Priority	Remove	Add	Reason
1	1 Forbidden Chalice	1 Side Deck slot for a flexible answer	Adding a side deck is the largest documented gap (D12); a flexible answer gives post-side adaptation without changing the engine.
2	1 Cosmic Cyclone	1 additional Plant starter	Reduces dependence on the non-monster share and raises starter density for the Plant engine (Inferred).

Evidence & confidence

Verified: Main 55, Extra 15, Side 0; legal under OCG size rules (40-60 main, 0-15 extra, 0-15 side); All cards Unlimited in the OCG banlist; no Forbidden or Limited cards; Copy histogram 3-copy x12, 2-copy x6, 1-copy x7 (matches the card list); Extra Deck is 15 Xyz monsters, 9 distinct; Side Deck is empty
Observed: Usage statistics: 10 of 23 archetype core cards present (43.5%)
Inferred: Starter and searcher hypergeometric probabilities; Engine accessibility and brick estimate; Interaction density from text hints; Boss ATK and closing power; Going-first and going-second estimates
Provisional: Meta power and matchup fit: no dated metagame sample
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: going-first, going-second and matchup results unknown Meta Power is Provisional unless a dated metagame sample is supplied deck title is null
