JouganTbh, I think the Jōgan is what will grant Boruto what we're looking for in his moveset.
Take a look at the 4 Momoshiki abilities I listed above, and you'll notice they aren't particularly groundbreaking.
1. Momoshiki can shape constructs out of surroundings, but we've seen that before in the form of Hashirama creating wooden constructs, Susanoo, etc.
2. Black receivers have been used by other Rinnegan such as Nagato, Obito, and Madara.
3. Hair manipulation has been employed by Jiraiya and Kaguya.
4. Kinshiki's ability to create weapons is shared by Susanoo users, who can create a wide range of weapons such as bow & arrows, swords, shields, etc.
The Jōgan may present us with an ability that's never been seen before, and that's what I want to see.
