3 Level 7 monsters You can detach 1 Xyz Material from this card; roll a six-sided die twice and this card's ATK becomes the larger number rolled x 700 until your opponent's next End Phase, then if the total roll was exactly 7, apply 1 of these effects. ● Send all other cards on the field to the Graveyard. ● Special Summon 1 monster from your hand or from either Graveyard. ● Draw 3 cards, then discard 2 cards.
Number 7: Lucky Straight — Power Evaluation
Final Score: 47 ± 5 · Confidence: Medium
- Intrinsic: 48 · Deck: 48 · Meta: provisional
- Primary role: Boss / End-board · Secondary: Utility
Why it scores here
Lucky Straight scores as a niche end-board XYZ that appears in diverse themes but lacks reliable payoff. The card spreads across 48 archetypes and averages 1.13 copies per deck, confirming it fills a genuine role—but its 16.67% conditional trigger rate (rolling exactly 7 on 2d6) and weak 700/700 base stats sharply limit its utility. The powerful effects (board wipe, recovery, draw) are compelling when they fire, but the randomness and Xyz Material dependency make it a secondary option rather than a strong finisher.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Appears in 119 decks across 48 distinct archetypes with a 1.13 copies/deck average, confirming accessibility in Level 7 Xyz-heavy themes like Kashtira (observed) |
| Combo & Conversion | 35 | No combo evidence supplied; text-only inference shows the card functions as an end-board piece, not a combo starter, requiring three Level 7 monsters and material detach before effect triggers (inferred) |
| Resource Economy | 30 | Each activation costs 1 Xyz Material detach with no guaranteed return; the draw effect (+1 net) triggers only on rolling exactly 7, roughly 16.67% of activations (verified from text) |
| Effect & Interaction | 45 | Conditional board wipe effect (send all other field cards to GY) is powerful and hard-to-answer, but only activates on rolling 7; no reactive negation or protection (verified from text) |
| Material Utility | 40 | 700/700 stats are below-average for a Rank 7 Xyz and limit use as intermediate material; Fairy/LIGHT type provides modest generic utility (verified from text) |
| Resilience & Flexibility | 35 | No built-in protection; relies entirely on Xyz Materials for effects; weak base stats leave it vulnerable to removal; random payoff limits strategic planning (verified from text) |
| Deck-Building Efficiency | 50 | Runs 1–3 copies per deck (most often 1) and appears in 48 archetypes, confirming it is a splashable end-board option rather than an archetype lock (observed) |
Calculation
Weight profile: Boss / End-board role (primary). Intrinsic ≈ 48, Deck ≈ 48, Meta = provisional. Modifiers: RNG-dependent payoff (-2); Broad archetype accessibility (1). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Appears in 48 distinct archetypes, confirming broad accessibility
- Powerful conditional effects (board wipe, recovery, card draw) when triggered
- Flexible three-option payoff accommodates different situations
- Generic Rank 7 Xyz body for Level 7-based strategies
Weaknesses
- Requires three Level 7 monsters to summon (high setup cost)
- 700/700 stats are weak as a standalone body
- RNG-dependent payoff (16.67% chance to trigger conditional effects)
- No built-in protection; vulnerable to hand traps and board interaction
- Entirely dependent on Xyz Materials; becomes dead once depleted
- Not ranked as top-card; secondary/tertiary end-board option
Counters / choke points
- Ash Blossom & Joyous Spring
- Infinite Impermanence
- Called by the Grave
- Effect negation (Any negate kills the die-roll effect)
Best use
End-board Xyz finisher with conditional board wipe. Decks: Kashtira, Odd-Eyes, Mekk-Knights, Knightmare, Rank 7 XYZ-heavy decks.
Evidence & gaps
- Verified: Card requires 3 Level 7 Xyz monsters to summon (card text); Effect: detach 1 Xyz Material, roll two six-sided dice, set ATK to larger roll × 700 until opponent's next End Phase (card text); Conditional trigger: if total roll equals exactly 7, choose one of three effects (card text); Three effect options: (1) send all other field cards to GY, (2) Special Summon 1 monster from hand or either GY, (3) draw 3 then discard 2 (card text); 700 ATK / 700 DEF body, LIGHT Fairy attribute, Rank 7 (card text); Appears in 119 decks across 48 distinct archetypes (deck data); Averages 1.13 copies per deck, most often run as 1 copy (deck data); Top partners are meta staples (Ash Blossom 63.9%) and archetype-specific cards (deck data)
- Observed: Kashtira is the most common home (26 decks = ~22% of sample), followed by Odd-Eyes, Mekk-Knights, Knightmare, Mulcharmy; 46.2% of decks running it are gameplay type 7 (mid-range control); Latest deck using the card is from 2026-09-17 (current meta presence); Consistent inclusion across multiple archetypes confirms accessibility of Level 7 Xyz summoning
- Inferred: The card functions as an end-board payoff rather than a combo starter (die roll and Xyz material costs indicate latgame use); Trigger rate for conditional effects is ~16.67% (rolling exactly 7 on 2d6 occurs in 6 of 36 outcomes); Randomness makes it unsuitable for deterministic combo planning; Level 7 Xyz summoning is the primary accessibility barrier; not plug-and-play; The broad archetype spread (48 distinct) indicates generic appeal of Rank 7 Xyz slots rather than deep archetype synergy; Appears to be a secondary end-board option, with Number 11: Big Eye as primary (42.9% co-deck rate)
- Data gaps: No combos supplied — combo conversion is text-only inference with no real-world board evidence No guides supplied — no human context on the card's intended role or synergies No banlist token — assumed unlimited (3 copies) in all formats No usage statistics (StatisticsCard) — archetype inclusion % and typical copies inferred from 119-deck sample only No top-card ranking — cannot confirm competitive viability beyond observed deck inclusion
