Why is Pokemon TCG not on phones? We certainly understand the desire for phone versions of the game. We want to play on our phones too. The game was originally designed for a robust (wifi or wired) data connection on a PC. The game has not been optimized for use over a limited cellular connection, that players on a smartphone might expect.
