Just win all your matches and it'll take half that time. What I did was that I just invested all my coins into the shop so I could field more Bangboos. Most players won't be able to handle it. I'm not sure if it was Butlerboo or not, but I'm pretty sure it was, but he was able to bring in another Bangboo before I hit the 5 limit and it just kept being easy pickings all the way through.
