There are many different archetypes in Dragon Luster, but all of them are dragons or offer support for high-level dragons. Craft a House or Chamber Dragonmaid to unlock this pack, and use your gems from Solo Mode to get it as one of your first.

Borrel is an excellent addition if you’re building Dragonmaid or Flowandereeze decks. You’ll want the Borrelsword and Borreload Dragons to cut your opponents down to size, while the Boot Sector Launch spell is a necessity for arrogant opponents with too many monsters on the table.
