From Bulbapedia, the community-driven Pokémon encyclopedia.
Pokémon Battle e: Series 2 (Japanese: 第2弾 ポケモンバトルカードｅ＋ Second Shot: Pokémon Battle Card e+) is the second collection of Battle e cards. It provides a new array of Trainers to battle as well as new Berries to use in Pokémon Ruby and Sapphire. It was released in Japan only.
There are 54 cards in the set. 48 of them are Trainer cards; 6 are special Berry cards.
This collection retains all of the elements featured in the previous set. An additional feature is the appearance of Trainers with Shiny Pokémon. Due to the poor reception of the e-Reader outside of Japan, this set and all subsequent releases were never translated.
