Several of the secret rare cards from SM12a TAG All Stars were just revealed at Tokyo’s Champions League tournament!
A new Mimikyu and Jolteon will also appear in the set. They were only partially revealed, however:
Ability: Shadow Box
As long as this Pokemon is in play, each player’s Pokemon-EX or Pokemon-GX with damage counters on it has no Abilities.
Its Ability is called “Speedy —–,” and has an effect on your Eevee in play.
The set will release in Japan on October 4th.
