Pokemon.com has announced that the same rule changes coming to the Japanese TCG on November 8th will be coming to the English TCG on the exact same day with the release of the Kalos Starter Sets.
Also revealed is that Professor Sycamore is card #122 in XY.
Flip a coin before drawing your opening hand. The winner of the coin flip now decides who goes first. Also, whoever goes first now can’t attack on his or her first turn. If you win the flip, decide carefully if you want the first turn or not!
Errata – Pokémon Catcher
Flip a coin. If heads, switch 1 of your opponent’s Benched Pokémon with his or her Active Pokémon.
Changes: This card now requires a coin flip. (This makes Pokémon Catcher functionally identical to Pokémon Reversal.)
Professor Juniper and Professor Sycamore
While there are no functional changes to these cards, 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.
