When an attack is declared involving a "Crystal Beast" monster: You can Special Summon this card from your hand. You can banish this Continuous Spell; Special Summon 1 Level 4 or lower "Crystal Beast" monster from your Deck, but negate its effects (if any), and if you do, add 1 "Ultimate Crystal" monster from your Deck to your hand.
Crystal Beast Rainbow Dragon — Power Evaluation
Final Score: 62 ± 6 · Confidence: Medium
- Intrinsic: 61 · Deck: 67 · Meta: provisional
- Primary role: Starter · Secondary: Recovery/Recursion
Why it scores here
Crystal Beast Rainbow Dragon scores on how reliably it converts a Crystal Beast attack declaration into a board: it can be Special Summoned from hand, and banishing its Continuous Spell brings a Level 4 or lower Crystal Beast from the Deck (negated) plus an Ultimate Crystal to hand. Its 3000 ATK earns nothing on its own, and the score rests on the conditional hand access, the 1-for-2 style value in the observed boards, and its ability to survive destruction by staying on the field as a Continuous Spell. It is archetype-locked and offers no opponent interaction, which holds the score back.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 72 | Hand-summonable only when a Crystal Beast attack is declared, and it is a starter in 1 of 3 recorded boards (observed, with inference on the attack-declaration timing). |
| Combo & Conversion | 78 | Recorded boards containing it average power index 87 (100, 87, 74), with 4 boss monsters on the best board (observed, plus text-based inference). |
| Resource Economy | 68 | Banishing the Continuous Spell adds an Ultimate Crystal and summons a body from Deck, with netCardAdvantage of 3 to 5 on recorded boards (verified text, observed board stats). |
| Effect & Interaction | 15 | No opponent-facing negate, removal or hand trap; its only negation targets its own summoned monster (verified text). |
| Material Utility | 35 | Level 8 Light body, but no Level 8 material or Xyz/Synchro usage is in the evidence, so material value is inferred and modest. |
| Resilience & Flexibility | 70 | If destroyed in a Monster Zone it can be placed face-up as a Continuous Spell instead of going to the GY, and each effect is once per turn (verified text, inference on resilience). |
| Deck-Building Efficiency | 55 | Runs 1 to 3 copies (average 1.87) in a deck built around the Crystal Beast archetype, which narrows its slot value (observed copy distribution, inference on restriction). |
Calculation
Weight profile: 0.7 Starter + 0.3 Recovery/Recursion. Intrinsic ≈ 61, Deck ≈ 67, Meta = provisional. Modifiers: Archetype lock (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Hand Special Summon triggered by any Crystal Beast attack declaration
- Banish-cost effect nets a Deck body plus an Ultimate Crystal to hand
- Destruction in a Monster Zone keeps it on the field as a Continuous Spell
- Appears in every recorded combo with a high average power index
Weaknesses
- Hand effect depends on a Crystal Beast attack being declared
- Archetype-locked; generic utility outside the family is weak
- No opponent interaction
- Effects are once per turn and the Continuous Spell route needs a free Spell/Trap Zone slot
Counters / choke points
- Negation of its hand effect or of the Continuous Spell
- Floodgates or once-per-turn locks on Special Summons from hand
- Board breakers that wipe monsters and Spell/Trap cards
Best use
Starter and recursive body in Crystal Beast boards. Decks: Crystal Beast, Crystal Beasts, Advanced Crystal Beast. Suggested copies: 2.
Evidence & gaps
- Verified: Hand Special Summon once per turn when a Crystal Beast attack is declared; Banish-cost effect summons a Level 4 or lower Crystal Beast from Deck (negated) and adds an Ultimate Crystal; Destruction in a Monster Zone allows placement as a Continuous Spell
- Observed: In 400 of 400 sampled decks, 1 to 3 copies (average 1.87); Appears in 3 of 3 recorded combos; starter in 1, in end hand in 1; Average power index 87 across recorded boards; Inclusion 80 to 100% in the Crystal Beast archetypes
- Inferred: Hand access is reliable only on turns with a Crystal Beast attack, so accessibility is conditional; Material value is modest because no Level 8 material usage is recorded
- Data gaps: no banlist token; 3 copies assumed (unlimited) no Level 8 material or Xyz/Synchro usage evidence no rulings data combo sample is only 3 boards
