Lets be honest, 1st Edition Base Set Shadowless Charizard is a badass card
Chief among these is Vampire Gourmand, which can turn each of the familiars lives into a card, but sacrificing the Familiar to Hungry Ghoul or Eaten Alive feels pretty great too
On top of that, this creature even comes with removal evasion, as simply killing this creature will create a token of itself (and then gives the owner another free card draw and 3 life), so you'll have to exile this to really get rid of it
This attacks damage isnt affected by Weakness or any effect on your opponents Active Pokemon
One of Giovanni's Team Rocket grunts has a Blastoise, but won't attack with it if he has 3 Water Energy attached
Also, the set wanted the Horror and Nightmare creatures to be enchantment creatures, so calling them all out felt repetitive
