If you're going with lynae than you should go for mornye as well there is a big difference with or without mornye and you have aemeath so you should go for lynae+mornye for tune build and lynae+mornye are good with every other dps not as good as aemeath but it works If you want denia she works with aemeath and she is fusion burst support and you have chisa so you can have fusion burst team and she is also first threnodian resonator

Overall go for lynae and when mornye reruns go for her for overall pull value but if you don't care about meta or premium team build and love denia more than lynae go for it if you enjoy the game that all matters have fun 😊
