There are several cards of dubious value to even moderately experienced players that could have been replaced with something better... but these
are Theme Decks after all, a.k.a. Starter decks. Even for as simple as Quick Ball and Evolution Incense seem, to a new player, they'd be a bit tricky. Which is why I'm grateful that Professor's Research made it into the decks at all, let alone in triplicate; when you're a newbie, knowing when to discard your hand and when to hold off for a turn is quite difficult!
Throw in the fact that I'm sure the powers-that-be - and some player/collectors - would prefer to
not have a bunch of booster pack pulls - that would have otherwise seemed good - soured by the fact that "Oh, yeah... I already have a play set thanks to the Theme Deck."
Nothing is helping Hop, Great Ball, or Potion in that regard.
