"You can farm Gold Bottle Caps at the Battle Agency Grade 50."

I cleared the Battle Agency (reached grade 50) today and found out each time you beat grade 50 level, you will get a Gold Bottle Cap as reward. You can beat level as many times as you wish to, it is not limited per day.Grade 50 level is 5 challenges (3 battles each as usual, you and your opponents will have lvl 100 pokemon), last challenge will have a boss battle. After beating the level boss you will receive your reward. Battles are not that hard (cleared level twice today without single loss with partners which had pokemon lower level than 100). If you are curious, here's video of my latest boss battle: VKMW-WWWW-WWWA-ZC74If you have issues with finding partners for Battle Agency, just add to friends/VIP other BA players, there's a subreddit for Battle Agency already! Also, if you've found a random guest with decent grade - page them from the left corner table of Plaza Castle so you will be able to VIP them. If you will have active players in your VIP list, you will never have any issues with having a solid team.Other than Gold Bottle Caps you are gaining a massive amount of Festival Coins you can spend on whatever you want. I got about 150000 FC on my way to Grade 50 and spent them on ton of bottle caps (Treasure Hunt) and ingame items which are laughably cheap in plaza stores.Pictures of getting grade 50 and rewardsPictures of clearing grade 50 level and getting rewards via /r/pokemon http://ift.tt/2iAgF0v
