Priest, rotation target:
4 stun window, 2 Yixuan ult on each stun + 1 decibel ult at the start of miasmic phase. If timed correctly (so the ult didn't miss when priest goes invincible), the extra ult provided by 
Ju Fufu will cut the miasmic phase time by a bit, giving a better chance for full fourth stun window. use 
Astra Yao ultimate for daze by Jufufu chain attack, or for damage inside stun by 
Yixuan double chain attack.

4-Pc Drive DiscYunkui Tales
2-Pc Drive DiscBranch & Blade Song
Build HP, CR, and CDGM. because of Astra Yao holding 
Unfettered Game Ball, the crit ratio threshold is easier to achieve (48% at W5). HP disc 5 performs better in Yixuan team that doesn't have a sheer force buffed (
Pan Yinhu or 
Lucia). 
Woodpecker Electro is also a valid 2pc option.

Threshold 50% CR and 3400 inital ATK. building full impact with 
Shockstar Disco 2pc + Impact disc 6 is better to guarantee a full 4 stun rotation in the fight.

2-Pc Drive DiscAstral Voice
3.58 ER with as close to 3429 initial ATK, but a bit lower than that is okay since ATK buff conversion to sheer force is not a lot. 
Astral Voice 4pc has a higher buff potential for Yixuan if the stack is managed to be maxed at every stun window, but 
Moonlight Lullaby 4pc is only -6% DMG% with an easier rotation.

How to Play & Additional Tips
The most important part in Yixuan damage optimization is on the stun window rotation. Using trigger chain tech to save time on her long ultimate animation into a Ju Fufu chain attack cancel is really good, so that the rest of the stun time can be used for Yixuan 
EX Special Attack: Cloud-Shaper. Ju Fufu and Astra Yao has a relatively easy buff to manage, though Astra buff needs a bit of attention if her ER is < 3.58, so Yixuan buff optimization shouldn't be a problem.
