The 2 most important things that you were missing were a mitigator (Aaron/Tesla) and a status nullifer (Ivris/Aurelia/Rigness/Ulkina). Assuming that the units you listed as your past main squad are your strongest, then an ASAP good squad would be

Zelnite/Lilly Matah/Oguro lead

Aaron

Ivris/Aurelia/Rigness/Ulkina (whichever you decide to raise first, though probably Rigness since it appears to already be 6*)

Yujeh or Selena

Zelnite/Oguro (if not lead)

Since all these units are at least all 6 star (except Aaron), hopefully you can get them all at least level 1 SBB. Make Aaron priority tho. This team should be plenty good for questing
