Not going to write essays, just watch the replays, it's broken.
I don't think many people used it too well, getting walled by Ferroseed often (HP fire looks like the best set, use it), or not pressuring the fighting types enough early games with ghosts so it can be revenged. Otherwise with spikes, weather chip and good play it looks super impressive, and you can always be tazz and flinch the checks.
Maybe i'm biased since I didn't want this in the first place, but there's been nothing in this tour to show me that my initial feeling about it was wrong.
