What are the differences between ex and gx Pokmon cards?

Ex and GX Pokmon cards are both powerful types of cards in the Pokmon Trading Card Game, but there are some key differences between them.

Ex cards were introduced earlier in the game and have higher HP and stronger attacks compared to regular Pokmon cards. They also give up two prize cards when knocked out in a battle.

On the other hand, GX cards are even more powerful, with stronger attacks and abilities. They also give up two prize cards when knocked out, but some GX cards have special GX attacks that can only be used once per game.

In summary, GX cards are generally more powerful and have unique abilities compared to Ex cards.
