I assume the legendaries are in the game, because I got a moltres. The enigma berry is just like the other berries, some cards need it (in my case once I gave moltres a glyph, the added berry cost was an enigma berry)
I imagined the legendaries were included and that the Enigma Berry had something to do with them, but since I never came upon one of them, it was just an assumption. Thank you for confirming. :D
