AttackPainful Sword
Double the number of damage counters on each of your opponent's Pokémon.

Aegislash is Pokédex #681, generation 6 (Kalos). Aegislash is a Stage 2 Psychic Pokémon with 140 HP. The card says it evolves from Doublade. In this catalog that name is Doublade (#680).
Aegislash sits at 62/122 in BREAKpoint, position 62 of 126. Before it is 61 Doublade, and after it is 63 Skrelp. The set belongs to the XY series. It was released on February 3, 2016. The printed size is 122. This checklist is longer, at 126 cards. The listed rarity is Rare Holo.
The attack Painful Sword lists no damage number. The cost is Colorless, Colorless, Colorless. Double the number of damage counters on each of your opponent's Pokémon. Megaton Slash is another attack lists 100 damage. The cost is Psychic, Psychic, Colorless, Colorless. This attack does 10 damage to 2 of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Weakness is Darkness ×2. Resistance is Fighting -20. Retreat cost is 3. The flavor text reads "Apparently, it can detect innate qualities of leadership. According to legend, whoever it recognizes is destined to become king."
Aegislash (#681) has 21 other cards in the catalog. Those other cards are in 12 sets. The other printings with a release date run from 2014 to 2026. The earliest other card is Aegislash 85/146 in XY (2014). Both list 140 HP. The rarity there is Rare, and here it is Rare Holo. 5ban Graphics illustrated that card, and Hitoshi Ariga illustrated this one. 16 other cards of Aegislash list a different HP.
The illustrator line reads Hitoshi Ariga. I count 155 other cards in the catalog with that illustrator.
BREAKpoint set binder is where a full BREAKpoint set goes. This card fills one slot there. A generation binder holds one card of each species. Aegislash can fill a slot in Generation 6 binder (Kalos). I still need this card.
