Fire/Lightning Battle Strength Set
| Release date
|| December 26, 2015
The Fire/Lightning Battle Strength Set (Japanese: バトル強化セット炎/雷) is one of three special Japanese-exclusive sets released on December 26, 2015 for the Pokémon Trading Card Game.
Included in this 16-card set are a small selection of Fire-type and Lightning-type Pokémon, as well as a number of supporting Trainer and Special Energy cards. The focal Pokémon-EX cards feature the Fox Pokémon Ninetales and the Lightning Pokémon Jolteon. Unlike the majority of fixed card releases in Japan, the set does not have its own collection number or symbol, with reprinted cards bearing numbers, symbols, and rarity from their source expansions, and new cards printed as XY-P Promotional cards. Each set also comes with a player's guide.
