In addition to looking fantastic with their crystalline appearance, some Tera Pokémon ex have another feature that makes them stand out—they have an Energy type other than what you might expect for that Pokémon (like a Fire-type Eiscue).

Otherwise, they follow the same rules as standard Tera Pokémon ex.
