POKEMON TCG ALTERNATE FORMATS

 - Only one of each card with the same name* is allowed in a deck, except for Basic Energy.
 - Banned Cards:
 - All ACE SPEC cards
 - All Pokémon with a Rule Box** (e.g. Pokémon EX, GX, V, BREAK, Radiant Pokémon, Prism Stars)
 - Chip-Chip Ice Axe (SM–Unbroken Bonds, 165/214)
 - Double Colorless Energy (SM–Shining Legends, 69/73, and all other versions)
 - Duskull (SM–Cosmic Eclipse 83/236)
 - Forest of Giant Plants (XY–Ancient Origins, 74/98)

*Similar to Expanded Format rules, you can either play Lysandre OR Boss's Orders in your deck, not both. The same goes for Professor Juniper, Professor Sycamore, and Professor's Research; you can only play one of the three.
**Ancient Traits are NOT considered Rule Boxes so those Pokémon are legal for Gym Leader Challenge.
