I love the concept but unfortunately these self buff stack NPs are usually underwhelming. The only good one is Super Orion and even then he's intentionally designed to not loop it easily. I'd love to see one like this that doesn't feel like they're actively being held back.
Hilariously, you know who I like using this way? Reines. Her NP post-buff gives her 30+% NP gain up, and the enemy 30+% DEF Down. Coupled with how ridiculously good her Arts cards are (a single Arts crit with just one NP up is honestly sometimes enough for her to fully refill her NP gauge), it's incredibly easy for her to spam her NP in a solo scenario.
On the third turn, assume she has all her buffs active, she's at +40% ATK the enemy is at -90% DEF
