Lana will be in SM4+ GX Battle Boost, but now as a full art Trainer! The set will be released in Japan on October 20th. In America, we’ll probably get Lana in our SM5 set, releasing in February.
A new Araquanid will be in SM4+ GX Battle Boost, but it’s the exact same card as the one from Sun & Moon except that it’s a Grass-type (it was previously Water). It has the same HP, Ability, attack name, and attack damage as the old one. Because it’s a different type and could also have a different attack cost and Weakness, it’s considered a different card. This is the first time in the history of the TCG that a new card shares the exact same attacks and Abilities as an older card.
