Why it scores here
Lavalval Chain is a generic Level 4 Xyz whose effect (detach 1 material: send 1 card from Deck to the GY, or place 1 monster from Deck on top of the Deck) converts a spent material into a small amount of deck control and fuel. Its 158-deck presence across 58 archetypes earns a modest score for portability and confirms it is a real, practical Extender, but the 1800 ATK and the high deck count did not earn points on their own. The card has no interaction, does not generate advantage, and its effect is limited to one use per turn, so the score stays near the middle of the range.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Needs two Level 4 monsters on the field to summon, and no searcher or starter route is supplied in the evidence; it is played in 158 decks, which supports practical access but not a live opening-hand route (inferred from deck data). |
| Combo & Conversion | 35 | Creates no board on its own; its effect only mills or places a monster on top of the Deck, and combo data shows zero recorded boards (text-only inference). |
| Resource Economy | 40 | The detach costs one material, the mill is self-fuel rather than card advantage, and deck-top placement is card selection without net gain (verified from card text). |
| Effect & Interaction | 5 | The card has no negation, removal, or hand-trap effect in its text (verified from card text). |
| Material Utility | 20 | As an Xyz it is not a generic material body, and its material is spent to activate the effect, so it contributes little when used as material (inferred from card text). |
| Resilience & Flexibility | 40 | Its 1800 ATK body remains if the effect is negated, but the effect itself is once per turn and depends on holding a material (verified from card text). |
| Deck-Building Efficiency | 65 | Requires only Level 4 monsters and appears across 58 archetypes, so it is easy to slot into many decks without garnets or locks (observed from deck data). |
Calculation
Weight profile: 0.7 Extender + 0.3 Searcher/Tutor. Intrinsic ≈ 48, Deck ≈ 50, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Generic Level 4 Xyz that is played across 58 distinct archetypes, showing it is portable between homes
- Deck-top placement gives limited control over the next draw
- Self-mill is a fuel option for GY-based lines
Weaknesses
- No combo evidence, so its conversion value is text-only inference
- Effect costs a material and is once per turn, limiting repeated value
- No interaction, negation or removal in its effect
- Needs two Level 4 monsters before it can be summoned at all
Counters / choke points
- Negating or banishing it on the field during its effect activation or after summoning removes the deck-control value, though the 1800 ATK body would remain
Best use
Generic Level 4 Xyz extender for decks that already run Level 4 monsters and want a deck-top or mill option. Decks: Infernity, Traptrix, Artifact, Atlantean, Mermail. Suggested copies: 1.
Evidence & gaps
- Verified: Xyz Monster, Level 4, requires 2 Level 4 monsters, 1800 ATK (card text); Once per turn: detach 1 material to send 1 card from Deck to GY or place 1 monster from Deck on top of Deck (card text); Appears in 158 recent decks across 58 archetypes; 81% of them in gameplay type 7 (deck data)
- Observed: Copies per deck average 1.25, with 127 of 158 decks running one copy (deck data); Frequent partners include Mystical Space Typhoon (69%) and Number 101: Silent Honor ARK (66.5%), which are generic staples (deck data)
- Inferred: Its role as a deck-top placement tool gives it limited Searcher-like value (text-based inference); Its deck presence reflects generic Level 4 Xyz use rather than intrinsic power (guardrail 3, inference)
- Data gaps: no combos supplied; combo conversion is text-only inference no guides supplied no usage statistics (StatisticsCard); archetype inclusion inferred from the deck sample only legal copies reads 0 in every format; treated as unrestricted because 158 decks run it, but not verified against the banlist no top-card ranking (top-card status false)
