Yesterday, while completing a trade with a friend, we noticed that one of the options presented to two Platinum carts over wifi is "Battle Frontier," essentially allowing you to fight through all of the facilities versus NPCs under the various rules, without needing to fuss through that two DSes in close proximity crap.
What's more, they give you a shitload of BP compared to the Frontier itself. The first streak versus pitiful things gets you 8. I suppose the only problem from then on would be playing someone with crappy wifi that drops often, but neither of us have that problem, at least not the dropping bit. Since we happened to be on the phone before deciding to trade, we didn't have to fuss with the voice chat or annoying reverb, either.
It was at least fun enough to prompt us to come up with a Trick Room team, which I then hacked and will trade him two of them to use alongside the other two.
Anyone else mess around with that? Sure it's haxtower, but it's a fun novelty for now >_>
