To keep pulling on Trick Or Defeat or to save?

I finally got Halloween Jakob and Henry but Jakob is +spd-def and Henry is +atk-def. Should I keep pulling in hopes of better IVs or is there anyway to work around those IVs? Should I also pull Henry for Armor March? I had 400 orbs going in and now I have 313. I also have not pulled on Land’s Bounty or Tempest Trials. I have a DC Myrrh but she is -atk+res and I have no more DC fodder, will an extra Myrrh for Hone Dragons be worth it? I kind of want to save for the legendary banner though. I have two CC fodders but no Fighter skills. I asked this before but it was midnight and barely anyone replied.
