As I looked on my RIX booster loots, I pondered on why the Pirates deck was only Blue Black when in fact Red also featured some of the aggressive one-drops of the tribe. That may be caused by the printing of Goblin Chainwhirler which can kill most of them. I then decided that since it is a tribal deck archetype, why not add White to be able to access Radiant Destiny? Here below is the resulting list:

Creatures
4 Bomat Courier
3 Captain Lannery Storm
4 Daring Buccaneer
2 Dire Fleet Daredevil
4 Rigging Runner
4 Fanatical Firebrand
3 Goblin Chainwhirler
3 Hazoret the Fervent
3 Kari Zev, Skyship Raider

Spells
4 Lightning Strike
4 Radiant Destiny

Lands
4 Clifftop Retreat
4 Inspiring Vantage
14 Mountain
