Crystal Beasts are a popular anime archetype that recieved an astounding series of support last year with their structure deck, which helped fix a lot of problems they had before, and are coming up on another powerful piece of support very soon, "Golden Rule". This card allows you to set 2 Crystal Beasts from your Deck as face-up Continuous Spells, then Special Summon 1 Crystal Beast monster from your hand with a different name from the cards you placed. Notice how the 2 you set from the Deck can be the same name. So what you can do is set 2 Sapphire Pegasus from your Deck, and Special Summon Ruby Carbuncle from hand, and Summon the 2 Pegasus from your Spell & Trap Zone to set other Crystal Beasts from your Deck.
This archetype has become easily able to make Rank 4s, most popularly "Time Thief Redoer" and "Lightning Chidori", but due to the Crystal Beast monsters staying the Spell & Trap Zone instead of the GY, the deck is easily able to utilize the infamous Dimension Shifter and Dimensional Fissure. Overall, a rogue deck that can stand up to the current meta, but not dominate it.
