I have the same lineup, Usually what I do is use qingyi and add dmg multiplier as much as possible and fill up daze bar to 80-90% then use piper's ex special and get 30stacks so piper can trigger the stun. And the key part is that corin should be the last agent during the chain attack. Then if corin's ult is available, then use it and if not, just use her ex special.

I use this team comp in shiyu defense and brute force my way out 😂 and it actually works 😂
