Recnbtly was confirmed that the title of BWS2 19 is "The Unova League Higaki Topurnament gets Underway. Sushi decided one-month ago that the thread is only for the first episode of the league, meaning that the general league discussion needs to be moved to another thread.
This thread is for General Discussion of the League, basically who will win, who will lose, discussion about possible evolutions in it, the rivals' interactions in it. Basically threads that is about more than one episode away.
The other thread is about BWS2 19, and specualtion about will happen only in this episode.
EDIT1: To look about older posts, I give a think to this page.
Please only talk about this particular episode, not about the big battles that won't happen in this episode as a possible. the latter is posted here.
EDIT2: Surprisingly, the league start in the first episode with Ash vs Trip directly. And we have two episodes for him already. Expect 3 vs 3+
EDIT 3: It's highly unlikely a 1 vs 1 because the Ash vs Trip battle is in the first episodes. High possibilities of cliff-hanger between episodes.
EDIT4: Stephan's Zebstrika and Kotetsu's Ferrothorn fighting a CotD because the two pokemon are on the right. Also, will be new information about it in Pokemon Smash.
EDIT5: Pokemon Fan revealed. With this match-ups.
