1. Path of the Dragon Queen - I love this subclass, this is a great usage of the theme and a really fun and effective Barbarian class. This is a Barbarian class that I would play (and I generally don't play Barbarians in more than one shots).
2.The Maverick - This is a missing trope from D&D and really needed represented. It's a great use of the theme and concept.
3. Rogue - Hand of the Dead - Another good implementation of the gambler trope. I like how the gambling that you do has combat implications as well as out of combat uses.


Theme:
1. Bigger is Better
2. Warriors of Old
