Same mistake being made with this set that was made with Shining Fates (obviously TPCi disagrees, since Shining Fates was a great seller for them, as I'm sure this set will be as well). Hidden Fates was released near the end of the SM bloc, which gave them nearly three years' worth of GXs to "shinify." Shining Fates had only a year's worth of V/VMAX to make shinies from, so they overbloated the set with "baby shinies" -- which aren't terrible, but not as cool as full art shinies.
Paldean Fates will be the same as Shining Fates. Too many baby shinies, not enough full art ex Pokemon to make shinies of.
