Assassin/Ninja Help Air Assasin

Hi
I looking for a good air assasin spell build without mythic! (hive dagger??)
At least 5 mana regen and no negative (easily powderable) defenses.
Thanks

https://wynndata.tk/s/4C7NA3 less rip hp but sort of rip mana and ele def also better damage
https://wynndata.tk/s/zEfvBX rip earth def
https://wynndata.tk/s/0mycua rip hp again, also pretty sp tight

note that you don't need a perfect agi capri + leictreach (for example, 7agi capri + 8agi leictreach works, or 5agi capri + 10agi leictreach etc etc)
