The DARK Dragon monsters are from the newest generation Yu-Gi-Oh! VRAINS. Coming across them in my online duels, I worked out how they play. Using link monsters and their own effects, in combination, they allow a variety of offensive moves that are fun to use.

The main cards in this consist of mostly the Link monsters in the extra deck. Because you need them to activate each unique effect of the normal effect monsters. Luckily most of them require only two sacrifices.
Get either Absorouter Dragon or Exploaderokket Dragon to the graveyard using Quadborrel Dragon, Twin Twister or destroyed from the field, then if you have a Rokket Synchron then you can synchro summon them together to summon the strongest monster Borrelload Savage Dragon the field.
Nearly all the Rokket cards allow you to special summon them one way or another, even some of them allow multiple summonses from the deck, graveyard or hand.
Protection cards include Power the Guardian, Imperial Iron Wall, Dragon Shield, Return of the Dragon Lords, Royal Decree, and extra monster effects.
