While there are no functional changes to these cards [Professor Juniper and Professor Sycamore], you may not include both of them in your deck. That is, you may have up to 4 copies of Professor Juniper or up to 4 copies of Professor Sycamore - but if you have any Professor Juniper cards in your deck, you may not put any Professor Sycamore cards in your deck, and vice versa.

Errata » Exp. Share
This version of Exp. Share [from Dragon Vault] was printed without the Pokémon Tool rule box. This card should have that rule box, matching Black & White - Next Destinies #87/99.

Errata » Great Ball | Trainers » Great Ball
The wording of Great Ball is now as follows, "Look at the top 7 cards of your deck. You may reveal a Pokémon you find there and put it into your hand. Shuffle the other cards back into your deck." This card works very differently now; it can no longer search the entire deck for a Pokémon and put it directly onto Bench.

Errata » Rare Candy | Trainers » Rare Candy
The wording of Rare Candy is now as follows, "Choose 1 of your Basic Pokémon in play. If you have a Stage 2 card in your hand that evolves from that Pokémon, put that card on the Basic Pokémon. (This counts as evolving that Pokémon.) You can't use this card during your first turn or on a Basic Pokémon that was put into play this turn." So now it can't be used on your first turn, and it can't be used on a Pokémon played this turn.
