It was nice seeing Ash actually try and catch the Roggenrola the first time not knowing that it wanted their help that felt real, as opposed to past episodes where they'd just go and help the Pokemon. Also enjoyed seeing an actual practical machine used by TR.

Well grats to Ash for getting a Roggenrola that puts his Unova Pokemon at 8, I just hope the writer's actually have Ash use them more than once, infact I wouldn't mind seeing a team comprised of Pokemon he caught after his sixth.
