Honestly it's not a good deck, just got lucky enough that I didn't run into much of the newer decks outside of crobat ex/espeon ex. Goal is just try to set up both primas and outheal everything, pyuku helps to stall and get things into kill thresholds.
You will almost certainly lose against 2x oricorios unless you can outplay them with pyuku/non-ex prima and heals.
You don't really need Misty or Irida, I just use them because I have the FAs. Maybe a Giovanni to one shot Oricorio with non ex-prima or Sabrina/Repel to phase it out.
