But some things are confidential, and I would have to tell you via PM.
But I'd like you to ponder about a few things:
-How exactly are Team Flora going to one step ahead of you? (As in, they take the stone, but you still have to battle them)
-Should the Team Flora Base be in a City and undercover, or be in the outskirts of somewhere?
-How would the rival tie in with all of this?
-Would other legendaries be involved?
