Crystal Beast Ruby Carbuncle — Power Evaluation
Final Score: 64 ± 6 · Confidence: Medium
- Intrinsic: 60.3 · Deck: 66.7 · Meta: provisional
- Primary role: Extender · Secondary: Recovery/Recursion
Why it scores here
Ruby Carbuncle is a cheap Level 3 Crystal Beast body whose value is extending the archetype: its Special Summon effect pulls other Crystal Beast monsters out of the Spell & Trap Zones, and its own destruction-in-Monster-Zone clause keeps it on the field as a Continuous Spell instead of sending it to the GY. Its 300 ATK and Level 3 Light Fairy body earn nothing on their own. The strong deck presence (400 of 400 sampled decks, 43 archetypes, about 92% co-occurrence with the top Crystal Beast partners) confirms it is a live, practical piece, but the combo sample is thin (3 boards) and none of those boards assign it a starter, searched, or payoff role, so combo_conversion stays moderate.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 70 | Runs in 305 of 400 sampled decks and co-occurs with the core Crystal Beast partners at 70% or higher, but the combo data does not show it being searched or started from (observed). |
| Combo & Conversion | 60 | Appears in 3 of 3 recorded combos with an average power index of 87, yet has no starter, searched, material, or payoff role in any of them, so its contribution is indirect (observed). |
| Resource Economy | 55 | The destruction clause keeps the card on the field as a Continuous Spell rather than losing it, which is a form of recursion, but no card advantage or GY refuel is measured (inferred from text). |
| Effect & Interaction | 10 | The card has no negation, removal, or hand-trap effect (verified from text). |
| Material Utility | 50 | A generic Level 3 Light body that can serve as Level 3 material, but it leaves the Monster Zone when its destruction clause applies and the evidence has no material-role combos (inferred). |
| Resilience & Flexibility | 70 | The Continuous Spell re-placement clause lets the card survive destruction in the Monster Zone and stay useful across turns (verified from text). |
| Deck-Building Efficiency | 75 | Runs an average of 1.39 copies per deck, is a cheap archetype body, and has no garnet or lock restriction in the evidence (observed). |
Calculation
Weight profile: 0.7 Extender + 0.3 Recovery/Recursion. Intrinsic ≈ 60.3, Deck ≈ 66.7, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Live in most sampled Crystal Beast decks, with very high partner co-occurrence
- Resilient: the destruction clause keeps it on the field as a Continuous Spell
- Cheap to run, with low copy counts and no garnet or lock restriction
Weaknesses
- No direct interaction: no negation, removal, or hand-trap effect
- Its value depends on Crystal Beast monsters being present in the Spell & Trap Zones
- Thin combo sample (3 boards) and no starter or payoff role observed
Counters / choke points
- Negate or disrupt the Special Summon effect
- Remove the Crystal Beast monsters it would pull from the Spell & Trap Zones
Best use
Extender in Crystal Beast engines: summons more Crystal Beast monsters from the Spell & Trap Zones and stays on the field when destroyed. Decks: Crystal Beast, Crystal Beasts, Advanced Crystal Beast. Suggested copies: 1.
Evidence & gaps
- Verified: Special Summon effect pulls Crystal Beast monsters from the Spell & Trap Zones; Destruction in the Monster Zone places the card face-up as a Continuous Spell; Level 3, LIGHT, Fairy, 300 ATK / 300 DEF; Appears in 400 of 400 sampled decks
- Observed: Appears in 305 of 400 decks with an average of 1.39 copies per deck; Appears in 3 of 3 recorded combos with average power index 87; Co-occurs with top Crystal Beast partners at 66% to 93%; Guides describe it as a float and search-support piece for the Crystal Beast engine
- Inferred: Acts as an Extender by keeping the Crystal Beast board going after it is destroyed; Its Level 3 body is a usable but awkward material
- Data gaps: No banlist token: assumed 3 copies (unlimited) Combo evidence has only 3 boards and assigns no starter or payoff role No dated metagame sample, so meta_power is null
