Branch Crystal Beast

The  Branch Crystal Beasts  are 7 monster cards based on the original "Crystal Beast" archetype, and are all Beast or Winged-Beast monsters ranging from levels 5-7, the only Level 7 one being "Branch Crystal Beast Diamond Chimera". They all have different attributes.

Play Style
Just as the "Crystal Beasts" focus on summoning the "Rainbow Dragon" card, the "Branch Crystal Beasts" focus on the summoning of a stronger "Aurora Dragon". The Branch Crystal Beasts all have the effect of being placed in the Spell & Trap Card Zone after they are destroyed, just like the Crystal Beasts. Several of the Branch Crystal Beasts can be Special Summoned by destroying certain "Crystal Beasts'" from the hand or field. The "Diamond Chimera" is an exception of this kind as it is Special Summoned by destroying two "Branch Crystal Beasts" from the hand or field.

Deck
A deck of Branch Crystal Beasts is recommended to have the "Aurora Dragon" and all 7 normal "Crystal Beast" cards in the deck as well, and it could be useful to also have the "Rainbow Dragon". With both archetypes together, the two dragons can be summoned quickly as several of the Branch Crystal Beasts can be Special Summoned by discarding Crystal Beasts, thus sending them to the graveyard and enabling the summoning of Rainbow Dragon quicker. If you can have the Rainbow Dragon on the field, you can use its effect to send the "Branch Crystal Beasts" on your field to the graveyard, which can support the summoning of "Aurora Dragon". Also, summoning "Branch Crystal Beast Diamond Chimera" can also quicken the summoning of the Aurora Dragon by Special Summoning it after discarding two Branch Crystal Beasts.

The two dragons together can form an excellent combo as they both have 4000 ATK and can double the trouble for your opponent. Also, both of their effects allow their ATK to increase, especially "Aurora Dragon" as it doesn't only allow you to sacrafice from the field, but banish from the graveyard as well, this ensuring that you can probably add 7000 ATK to it.
