Deck Concept
“Rainbow Bridge” lets you add the “Crystal” Spell/Trap Card you need for the situation from the Deck to the hand.
Fundamentally, you want to Special Summon “Crystal Beast” monsters with “Crystal Conclave” or “Crystal Beacon, while placing “Crystal Beast” monsters face-up in the Spell & Trap Zone with “Crystal Blessing”, all the while fighting with “Ancient City – Rainbow Ruins”.
With just “Crystal Bond” and “Crystal Beacon”, you can Special Summon “Rainbow Dragon” in one turn.
