Sigilyph-GX (LOT #98)

Ability • Mirror Counter

If this Pokémon is your Active Pokémon and is damaged by an attack from your opponent's Pokémon-GX or Pokémon-EX (even if this Pokémon is Knocked Out), put damage counters on the Attacking Pokémon equal to the damage done to this Pokémon.

This attack's damage isn't affected by Resistance.

This attack does 60 damage times the amount of Energy attached to your opponent's Active Pokémon. (You can't use more than 1 GX attack in a game.)
