Rainbow Bridge

Rainbow Bridge — Power Evaluation

Final Score: 63 ± 8 · Confidence: Medium

• Intrinsic: 61 · Deck: 65 · Meta: provisional
• Primary role: Searcher/Tutor

Why it scores here

Rainbow Bridge is a tutor that reliably searches Crystal Spell/Trap cards from the deck, providing consistent +1 card advantage. It appears in 100% of analyzed Crystal Beast decks at 3 copies and enables high-quality combos (average power 87), confirming its role as a core support card. The score reflects its narrow archetype focus, lack of board-building capability, and complete absence of opponent interaction—it is a pure enabler, not a power generator.

Axis scores

Calculation

Weight profile: Primary Searcher/Tutor. Intrinsic ≈ 61, Deck ≈ 65, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

• Extremely accessible via 3-copy density in all Crystal Beast decks
• Enables high-quality combos (average power index 87)
• 100% inclusion across all Crystal Beast archetype variants
• Simple, reliable tutor with clear timing and no rules complexity
• Consistent deck synergy; appears with top-tier Crystal partners

Weaknesses

• Archetype-restricted; tutors only Crystal Spell/Traps (not universal)
• Pure support card; generates no board presence or disruption
• Zero opponent interaction; cannot negate, remove, or disrupt
• Vulnerable to spell negation; spell speed 1 limits flexibility
• No material utility; spell card type prevents use as XYZ/synchro/link material

Counters / choke points

• Spell negation (Imperial Order, spell card removal)
• Hand trap negation (effect negation like Effect Veiler)
• Deck-out prevention (any effect limiting deck searches)

Best use

Core tutor enabling consistent access to Crystal support cards. Decks: Crystal Beast, Crystal Beasts, Advanced Crystal Beast. Suggested copies: 3.

Evidence & gaps

• Verified: Card text: Tutors 1 Crystal Spell/Trap from deck to hand (verified from complete card description); 100% inclusion across 400 analyzed Crystal Beast decks with average 2.87 copies; Appears in all 3 documented combos; Usage statistics confirm 100% inclusion in Crystal Beast, Crystal Beasts, and Advanced Crystal Beast archetypes; Guides confirm Rainbow Bridge as a core search card enabling access to archetype support
• Observed: 372 of 400 decks (93%) run maximum 3 copies; 25 decks run 1 copy, 3 run 2 copies; Combos featuring this card have average power index 87/100; Synergizes exclusively with Crystal-related cards (Sapphire Pegasus, Rainbow Dragon, Crystal Bond all 95.8% co-appearance); Found in 36 distinct archetypes, but concentration in Crystal variants is overwhelming (71.5% of analyzed decks)
• Inferred: As a Normal Spell with no once-per-turn clause, can be activated freely each turn if in hand (standard spell card rules); Each activation provides +1 card advantage via deck-to-hand search (tutor mechanic); Spell card type prevents use as synchro material, XYZ material, or link material (card type rules); Tutoring scope limited to Crystal Spell/Traps restricts splashability outside archetype
• Data gaps: No explicit combo role data provided (all role arrays empty); unclear how the card specifically contributes to each combo line No banlist token; assumed unlimited (3 copies) across all formats No top-card ranking; top-card status false with no ranking data Limited combo sample size (3 combos); may not capture full range of Rainbow Bridge usage patterns No metagame sample or dated tournament performance data provided
