As much as I love the idea of playing with my Pokemon, I'm gonna
have to go "no support" on this. First off, "train" is very vague.
Did you mean raising their level or their stats? In the case of
levels, it's completely unnecessary since you can already give rare
candies and just have other people click them, which is much more
efficient than a once-per-day thing. In the case of stats... We
already have the salon. Right now, the main-page of the salon's (as
in, not the furfrou section) only actual exclusive use is the
stat-boosting treatments, since you can use a soothe bell to raise
happiness instead. (Granted, soothe bells are harder to come by
since the shop doesn't always sell them, but they're instant so in
that case soothe bells are more useful than acupuncture.) If this
was implemented as a stat-boosting item, the main page of the salon
would be completely useless. And if it was just the "playing with
your Pokemon" part without the training aspect... We already have
that, technically. If you go to your party page and "pet" your
Pokemon with your cursor for a while, the sprite will jump up and
down and send out hearts. Sure, it's no Pokemon Amie, but that's
probably more than the frisbee thing would amount to. Making actual
animations for hundreds of Pokemon would be way too much work, so
it'd end up just looking like berry-feeding does on here, but with
a frisbee icon instead of a berry icon.
TL;DR - This already exists in some form or another. You can pet
your Pokemon in the party page, and we already have ways to train
Pokemon, so if this was implemented it would either be useless in
comparison to the other methods or kill off another segment of the
game that already exists.
