Due to an error in the card text for Garchomp (Sword
& Shield—Brilliant Stars, 109/172), the text on this card will be
changed. The original text for Garchomp’s Sonic Slip Ability says:
When you play this Pokémon from
your hand to evolve 1 of your Pokémon during your turn, you may prevent all
damage from and effects of attacks done to this Pokémon until the end of your
opponent’s next turn.
The original intention of this Ability was to provide protection only from the opponent’s attacks, not from your own.
The new text will say:
When you play this Pokémon from
your hand to evolve 1 of your Pokémon during your turn, you may prevent all
damage from and effects of attacks from your opponent’s Pokémon done to this
Pokémon until the end of your opponent’s next turn.
Effective immediately, Garchomp’s Sonic Slip Ability will
use this updated text instead of the original text. This will be reflected on
the Pokémon TCG Errata document.
