First up, the game has an extra mini special pack called First Partners, which was added along with the new expansion. True to its name, it has all current Pokémon of this class in the form of one Star full art cards - one each, which means only 27 cards. There is also only one card in its pack, and the pack can only be opened on a weekly basis. Therefore, it will take some time for any player to get all the cards in the pack, but all of them should be spectacular enough that the patience becomes well worth it to open each new pack as it comes.
Then, last month the game had the "Pika Pika! Pikachu" event, which featured special packs that contained three cards each, all certainly related to Pikachu. They had to be earned by logging into the game daily and opened afterwards. The event itself pertained to the 30th anniversary of the Pokémon TCG in general (beyond the Pocket realm), which makes it a special event; even the promotion for the event involved Pikachu in special guises similar to a certain music game. Though limited, it was quite relatable to the above.
Meanwhile, the new deck features are (were made) live alongside the new expansion. Rental decks are now available for the expansion up until the transition to the next one, and each can be used indefinitely. After a hiccup, Community Decks can now be viewed and built reliably, also showing just what cards are needed for them. There is also an new Theme Deck List for an Elite Deck featuring Mega Rayquaza that can be built if a player has space for it, which should be the case as they can now have 30 stored decks, a slight improvement.
It may be said that the recent additions above, which have the common theme of pertaining to decks and cards, are bringing a "new flavor" - as is the case with the recently added expansion and its cards with the new aspects. The next course of usefulness is then for the players of this game to determine, given the above explanations and discussion... which will also partially be determined by whatever further plans (cards) are in line for the game.
