I have a Salazzle GX deck in expanded, and I would argue that it isn't nearly as bad as some other GXs in the set.
Salazzle GX can heal completely with Max Potion and then recover all that energy with Blacksmith, or I can use Scramble Switch to set up a new Salazzle GX and either use Max Potion or Acerola on the benched Pokemon. For any deck that can't OHKO a 200HP Pokemon (or 240HP with Bodybuilding Dumbbells), they need to wait until I run out of Max Potion or Acerola. By then, I would have taken enough prizes to start taking OHKOs of my own with Diabolical Claws. Queen's Haze GX completely undoes Kiawe and sets any energy-reliant deck back a lot. Sure it doesn't have support in Standard, but I would argue that this card is better than Golisopod GX in Expanded.
