A very sad event for most Pokémon TCG players is the latest rotation. Now, all of the Black and White series is now in expanded only. This means a lot of cards, such as Mew EX and G-Booster are no longer able to battle. Also, many Pokémon have gotten weaker because of the loss of Hypnotoxic Laser, like XY Furious Fists' Drapion because if it only can do Venoshock when your opponent is not poisoned and it will be Knocked Out next turn, then it can't do as much damage.
