If this card is used as material for a Fusion Summon, and sent to the GY or banished: You can add 1 "Gem-Knight" monster from your GY to your hand, except "Gem-Knight Quartz".

Gem-Knight Quartz — Power Evaluation
Final Score: 58 ± 8 · Confidence: Medium
- Intrinsic: 57.5 · Deck: 61.5 · Meta: provisional
- Primary role: Searcher/Tutor · Secondary: Recovery/Recursion, Combo enabler
Why it scores here
Gem-Knight Quartz's value is in what it puts into play: its first effect sets a Fusion Continuous Spell from the Deck when the opponent controls a monster, and its second adds a Gem-Knight from the GY after it is used as Fusion material and sent to the GY or banished. Its body is a generic Level 4 Earth Fairy, so it scores on access and material conversion rather than ATK or DEF. The evidence is strong on deck presence (400 of 400 decks, 3 copies typical) but thin on combos (one recorded board, with no starter, searched or material role tags), so the score stays moderate and the 1500 ATK earns nothing.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 65 | Runs in all 400 sampled decks, typically 3 copies, but its first effect needs an opponent monster and a discard cost, and no searcher route is in the evidence (deck and usage data, observed; discard-zone wording and the access route are inferred). |
| Combo & Conversion | 60 | Appears in one recorded one-card board (power index 100) with 6 end monsters, but the combo role list is empty and the Fusion Spell set needs a Gem-Knight Fusion route to convert (single combo, observed; conversion route inferred). |
| Resource Economy | 60 | The discard-for-Fusion-Spell effect is roughly card-neutral, and the material-triggered GY recovery adds one Gem-Knight, with no measured netCardAdvantage beyond the one board (text, inferred). |
| Effect & Interaction | 15 | No negation, removal or floodgate text; only a turn-long Extra Deck Special Summon restriction that exempts Gem-Knight (verified text). |
| Material Utility | 70 | A Level 4 Earth Fairy body that converts into a Gem-Knight recovery when used as Fusion material, and its body remains valid as material if the effect is negated (verified text, inferred for negated case). |
| Resilience & Flexibility | 55 | Two effects across hand and GY/banish zones, each once per turn, but the first is dead without an opponent monster (verified text, inferred for zone spread). |
| Deck-Building Efficiency | 50 | Three copies are typical and there is no garnet, but the card is tied to the Gem-Knight archetype core and carries a turn-long Extra Deck summon restriction (observed deck copies, verified text). |
Calculation
Weight profile: 0.7 Searcher/Tutor + 0.3 Recovery/Recursion. Intrinsic ≈ 57.5, Deck ≈ 61.5, Meta = provisional. Modifiers: Self-locking restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Places a Fusion Continuous Spell from the Deck, which works as a search-like route into the archetype's Fusion plan (verified text)
- Recovers a Gem-Knight from the GY after material use, a refuel that stacks with the Fusion plan (verified text)
- Live in the Gem-Knight core across 400 of 400 sampled decks, with strong partner density (observed)
Weaknesses
- First effect is dead when the opponent controls no monster (verified text)
- Second effect requires the card to be used as Fusion material first (verified text)
- Only one recorded combo board, so the combo weight rests on little data (observed, data gap)
- Deck-locked to the Gem-Knight archetype, so it is a weak generic card (inferred from archetype distribution)
Counters / choke points
- GY or banish hate stops the material-triggered recovery (inferred)
- Opponent monster-free boards turn off the first effect (verified text)
Best use
Fusion setup and GY recovery in the Gem-Knight core. Decks: Gem-Knights (archetype 607), Gem-Knights (archetype 240), Gem-Knights (archetype 436). Suggested copies: 3.
Evidence & gaps
- Verified: First effect: when the opponent controls a monster, discard this card to set one Fusion Continuous Spell from the Deck and bar Extra Deck Special Summons this turn except Gem-Knight; Second effect: when used as Fusion material and sent to the GY or banished, add one Gem-Knight from the GY to hand, except Gem-Knight Quartz; Each effect is once per turn
- Observed: In 400 of 400 sampled decks, 3 copies typical (copies distribution 1:198, 2:5, 3:197); Top partners Gem-Knight Nepyrim (99.2%) and Brilliant Fusion (98.5%); One combo board at power index 100 with an empty role list; Inclusion 100% in the Gem-Knights usage archetypes
- Inferred: Discard location is not stated in the evidence, so the access route is unconfirmed; Fusion Spell set counts as a search-like route; Negated body still works as material
- Data gaps: No banlist token, assumed 3 copies (unlimited) Only one combo board, with no starter, searched or material role tags Discard zone not stated in the description evidence No ruling data
