Although the game has been out for just four months, Pokemon TCG Pocket's collection of cards is already quite impressive, and it's bound to grow larger still in the coming months - especially with set A3 being rumored to launch at the end of April. There are many hypothetical cards that could make for great additions to Pokemon TCG Pocket, such as upgrades to the Poke Ball, such as Mega Ball or Ultra Ball, including concepts that the physical version of the game already includes. Yet, because Pokemon TCG Pocket has different deckbuilding rules and criteria, it's hard to say if some cards from the physical version would end up in the game, particularly one existing card.
