That's more of a main board question, as you're not talking directly about battling. You're asking about the Battle Subway. --- ''Your drill is the drill that will pierce the Heavens!" http://i.imgur.com/MkNCuK6.jpg http://myanimelist.net/profile/Heaven-Piercing
Yes, but you're not asking about the battling in the facility directly, therefore it belongs on the main board. You're asking a question about the Battle Subway itself. If you were asking a question that was directly about battling in there, then it might belong here (Though most questions about the Battle Subway belong on the main board anyway as this board is geared toward competitive battling, not in-game battling). --- ''Your drill is the drill that will pierce the Heavens!" http://i.imgur.com/MkNCuK6.jpg http://myanimelist.net/profile/Heaven-Piercing
Yes, you gain 3BP or so every 7 battles, but once you get to 21 consecutive I believe you fight the Battle Subway master, who awards 10 BP upon defeat I believe.
Honestly, you're much better off just battling on random Wifi for BP. Though typically, you're going to be rage-quitted on quite often by angry Japanese kids.
Still, assuming your team is decent and you know what you're doing you should be able to rack up BP easily. I think I'm sitting at 250 extra BP at the moment and that's after buying all TM's, Power/Battling items, etc. --- We trained harder than you today, and we're gonna party harder than you tonight.
