Pokémon Japan has revealed the new sV3 expansion Ruler of the Black Flame .
The set will be released in Japan on July 28 and will feature 108 cards, not counting secret cards. This expansion will introduce the first Teracrystal Pokémon with unusual types such as Charizard ex (Dark), Tyranitar ex (Electric), and Eiscue ex (Fire).
This set will be coming to the West via Obsidian Flames on August 11th.
These Tera Pokémon ex will use the same Energy as their original types , but will have a different weakness to correspond with their changed types. For example, Charizard ex will be a Dark card with Fire attack costs and a Grass Weakness (in the TCG, Dark-types are weak to Grass to represent Bug).
