I tried the suggestion of placing a market next to my TC....got nicked for 30 MEDALS for only a 3 star victory lol!
I was super happy though because I found a fully loaded GA base worth 5 medals! Too bad it cost me my whole army....
(for the record, I occasionally see a fully loaded GA base worth 12-18 medals, but they are far too tough for me to even suicide against them for a 1 star victory)
