The Pokémon Company president Tsunekazu Ishihara took to the stage at the 2016 Pokémon World Championships opening ceremony, revealing Pokémon-GX will be added to the Pokémon Trading Card Game in early 2017.
These will come when the Sun & Moon Series is introduced, with the term GX used to describe special attacks and Pokémon that are completely new to the Pokémon TCG.
This will require players to plan new strategies, with The Pokémon Company outlining the new addition as below:
GX Attacks
Each Pokémon-GX has a devastating GX attack that can instantly reverse a player’s disadvantage or create an early-game advantage. A player can’t use more than one GX attack in a game, so deciding which GX attack to use and when poses a strategic challenge.
Pokémon-GX
In Pokémon TCG: Sun & Moon, Pokémon-GX will make their first appearance. There are four defining characteristics of Pokémon-GX.
Legendary Pokémon
The Legendary Pokémon Solgaleo and Lunala, who appear on the covers of the Pokémon Sun and Pokémon Moon video games, will be featured in the Sun & Moon expansion as Pokémon-GX.
The Sol Burst-GX attack allows a player to attach up to 5 Energy cards from their deck to their Pokémon in any way they like, making it a powerful attack that’s useful for super Energy acceleration.
The Lunar Fall-GX attack lets a player immediately Knock Out any of their opponent’s Basic Pokémon.
So I wonder if tis add the energy cards to any pokemon on your bench, or its just Solgaleo, Any bench pokemon seems much more useful.
