If you have Meteorite E2 lv 30+ or you friend have congratz today is easy !
basically you can replace any operators with direct upgrade.
you can also put any high dps ops like Eyja s2 or Exu in place of Shirayuki.
May dont even needed if you have better operator to replace Kroos with so you can just put extra dps in or w/e you like.
You can also let 1-2 drones pass and still get the rewards, as I missed time the Vermeil skill, 1 drone passed ; ;
I will try to upload multiple daily clear with easy to make team (with 1-2 5-6 stars that easy to find so you can just pick w/e you have)
Have fun and dont lose too much irl sanity with CC LOL
