battle liger zeroes on the north continent or berserk furies on the south continent on the south ruins

or you could just use the core security 1 deck command before you destroy a bunch of berserker furies. that's almost 75% chance success of getting a z core ux.

just get a core security 2 deck command it's like this battle a liger zero or bersek fury then leave one berserk fury or a liger zero behind the use the data gather 2 command then kill it its 95% correct or u will get a wild z data.

how go you get data gather. 2 ?
