Blue-Eyes Crystal Deck

This deck is definitely a work in progress but it is built around quick summoning a lot of monsters making for an easy setup that can give you Blue-Eyes White Dragon, Rainbow Dragon, and Rainbow Dark Dragon very quickly. Try to start with Crystal Conclave and any Crystal Beast (other than Pegasus). When it is destroyed in battle, Sapphire Pegasus can be used to quickly bring out another beast. When you draw another Conclave, destroy the one on the field to bring Pegasus to your hand. Set Conclave and summon Pegasus to summon another beast. Destroy Conclave once more to get Pegasus into your hand, then bring it out again to summon another Crystal Beast. The goal here is to quickly get out as many Crystal Beasts as possible. Use Torrential Tribute to send them to the graveyard and use Maiden, Master, or White Stone to get a Blue-Eyes out after. When all the types of Crystal Beasts are in the graveyard, you can summon Rainbow Dragon (ideally summon both). Use Advance Darkness and get remove them from play to summon Rainbow Dark Dragon. Deep-Eyes makes a good backup since it gains power based on dragons in the graveyard. I have not gotten to use it too much yet so it will likely have bugs to work out. It may work very well with cards like Stardust Dragon and other dragon synchros.
