I am at 6th Gym

Have a friend with a specific team make a secret base. The best teams are those that consist of 6 level 100 pokemon knowing selfdestruct or explosion (metagross and mewtwo; the latter is slightly better but more rare and the move tutor it needs is in a gamecube game) or a team of 6 level 100 blissys (low level teams can toxic stall).

Chase down that film crew that always asks to interview you after battling. They have an Exploud and a Magneton.
