I got the Golden Bottle Cap against my expectations but I'm not sure who to use it on. I think my three best candidates are the (purified) Apex birds and a Shiny Lucky Origin Dialga. Ho-oh is my favorite legendary but I already have a 14/15/15 Shiny maxed out, and I don't think it's worth it to use the cap to pump one point into Attack. Meanwhile I still don't have a good Dialga or Lugia. From what I understand Lugia isn't very good anymore which should make this an obvious win for Dialga, but holy shit Origin Dialga is hideous and I don't want to look at it.
