There are a few other problems with this set as well...
Carnivine's Swallow Up - "... If the Defending Pokemon has fewer remaining HP than Carnivine's, this attack does 60 damage instead." - "Carnivine's" should not be possessive? Trivial maybe, but still wrong. It's as if they started off saying "If the Defendning Pokemon's HP is less than Carnivine's..." and decided to reword (but only did half the job).
Skorupi's Pin Missile - "... This attack does 10 damage time the number of heads." Time? How about "times."
Drifloon's Blowing Wind - "... put 1 of your Benched Pokemon and all cards attached to on top of your deck." How about "attached to IT on top of your deck?
Nothing as serious as Empoleon's error, but it was just odd seeing so many errors in this set as I was updating the Pokepedia.
