CDP: Crystal Beast Golden Rule – Winning with Rainbow Dragon

The next powerful Crystal Spell approaches!


Strategic Summary:

Crystal Beast (CB) decks shine with a brilliance from all of the amazing Crystal Spells and Traps released over the years, as their monsters have always been one of their weak points. While Crystal Beast Sapphire Pegasus serves as a great way to kickstart a board by crystalizing Crystal Beast Rainbow Dragon and Crystal Beast Ruby Carbuncle can Special Summon tons of crystalized monsters from your backrow, the other 5 CBs are just… not good. So these powerful S/Ts really are the crutch keeping this deck going, whether it is Crystal Bond which tutors a CB and crystalizes another to your backrow or Crystal Beacon which Special Summons any CB directly from your deck. With their latest Structure Deck, the theme also received Awakening of the Crystal Ultimates and Rainbow Bridge of the Heart, two Spell Cards that increase the consistency of the deck by a large amount, giving you access to all of your other Crystal cards like never before. Add that to the pre-existing Rainbow Bridge and Crystal Tree, and you will be crystalizing your monsters and tutoring what you need constantly.

Then came Golden Rule (YGOrg Translation) in Premium Pack 2023 – this Equip Spell is everything the deck could ever ask for. First you crystalize 2 CB monsters from your Deck, then you get to Special Summon any CB from your hand or GY with a different name. It may seem simple, but when Special Summoning Crystal Beast Ruby Carbuncle with that effect, you’re just getting 3 monsters to your board for one Spell activation. This also lets you leverage any of those ‘not good’ other CB monsters as engine requirements, since they will often times just be summoned through this Golden Rule combo and then linked away for a Link Summon. With all of these names more easily accessible, Rainbow Dragon becomes even easier to summon than ever before, bringing with it two other bosses in Rainbow Overdragon and Ultimate Crystal Rainbow Dragon Overdrive, both of which boast ridiculous ATK power and an affinity for ending duels quick. Leverage the power of gemstones with the Crystal Beasts!
