What are the differences between Pokmon cards GX and EX, and how do they impact gameplay and card collecting?

Pokmon cards GX and EX are both powerful cards in the Pokmon Trading Card Game, but they have some key differences. GX cards have a special GX attack that can only be used once per game, while EX cards do not have this feature. GX cards also have higher HP and stronger attacks compared to EX cards. In terms of gameplay, GX cards can turn the tide of a battle with their powerful GX attacks, while EX cards are still valuable but may not have the same impact. In terms of card collecting, GX cards are newer and more sought after by collectors, while EX cards are considered classics and may hold sentimental value for long-time collectors.
