The names of the Theme Decks are taken from the Japanese name for the set.
EX Unseen Forces is the first set since Neo Destiny to contain Unown. In the English set, all 28 Unown cards are holographic and form a sub-set with its own numbering system, numbered as @/28. An Unown replaced the reverse-holographic card in every fifth pack.
The second “o” in Ho-Oh is capitalized in this set, unlike in previous sets where it was written in lowercase.
The reverse-holographic design for this set features a 3D Poké Ball pattern and the EX Unseen Forces set logo.
This is the last set to have an Owner's Pokémon ex.
The secret box topper for this set is Rocket's Persian ex. Another secret card, Celebi ex, appeared randomly in booster packs.
