Welcome to Gaia! ::

Uh huh.

... I remember people smuggling cards into school and trading them in the corner of the room at recess.

... My sister would scribble on my cards and rip them up. ... She owes me mad Pokémon cards.

They were banned from mine. ... it was so lame. crying

The old-school cards are considered broken in today's terms. xd

Few cards from the base set have been reprinted (a.k.a.: Pikachu), but if they became reprinted, then they have modifications so it wouldn't be so unfair.
For example (and everyone who plays the TCG should know this) there was a card called Gust of Wind which allows the user to switch the opponent's pkmon (active with a bench). It's like the video game's attack Whirlwind except that the user gets to choose who comes out. The reprinted version requires the user to flip a coin. If heads, then the person gets to do that fun stuff; tails, nothing happens. gonk

Same thing for another card Super Scoop Up (that's probably its current name; I didn't keep up with past trainers). The original card allowed the user to just take a pkmon and all cards attached to it into their hand. Later, it became a Supporter card (a trainer category that can be used only once per turn). Now it's a normal trainer that can be used as many times as a person wants, but that person has to flip a coin.

Obviously, the coin flipping/chance is the way pkmon creator people made things less broken so people question if they should have the card in their decks. sweatdrop I'm sure there're other examples, but the easiest modifications are in the trainers.
