The fast-paced nature of Pokémon TCG Pocket means the next set is always on the mind. Celestial Guardians is the game’s third main set, but all eyes are already on what’s next, and Pokémon TCG Pocket could be introducing Ultra Beasts—as suggested by a leak.
Dataminers are always on the case. They sift through game files in the hope of finding something juicy. Pokémon TCG Pocket content has pretty much been leaked continually since day one. Whether it’s Shining Revelry or Celestial Guardians, the next set inevitably leaks ahead of time.
But a new leak has gone early, showing the inevitable debut of Ultra Beasts.
Ultra Beasts Could be Coming to Pokémon TCG Pocket

Ultra Beasts were first introduced into the Pokémon universe with Pokémon Sun and Moon.
They’re considered to be extra-dimensional creatures with unbelievable power. Pokémon analyst and leaker @3clipse_tt has uncovered Pocket files featuring one eye-catching line: “IsUltraBeast” with the word “false” next to it.
This is likely a new line of code to identify if a Pokémon Pocket card is an Ultra Beast.
They add: “There are 10 UBs in total, excluding Poipole, so they can totally do a big set including all, like Shining Revelry.”
#PokemonTCGPocket Datamine Looks like they added the “IsUltraBeast” check for cards in the game, so it’s likely the next Set will include Ultra Beasts!
The next set is likely to be a mini-set, and as we are still in Celestial Guardians times (which are centered around Sun and Moon), this all makes sense.
Are you excited to try and pack Nihilego, Buzzwole, Stakataka, and the rest? Who’s your favorite Ultra Beast? Let us know via the Insider Gaming forum.
