We haven't seen one of these rulings passed since back in the Wizard of Coast days. Today, Play! Pokémon announced the ban of Lysndre's Trump Card from all tournament play.
As of June 15, 2015, Lysandre’s Trump Card (XY—Phantom Forces, 99/119 and 118/119) will be banned from all sanctioned Play! Pokémon tournaments in most of the world. (The ban will go into effect in Japan on June 20.) This card has created an undesirable play environment because it:
- Eliminates one of your opponent’s victory conditions (running out of cards in your deck)
- Allows repeated use of powerful Trainer cards
- Allows drawing through your deck quickly with minimal repercussions
- Extends the time of battles
All sanctioned tournaments will be affected by this change, including Pokémon National Championships occurring after June 15 (except in Japan) and the Pokémon World Championships in August.
