I've been trying to get every trophy in Super Smash Bros. for 3DS without resorting to buying them from the Trophy Shop. I've played flawless Trophy Rush games and various other modes over 400 times now (not exaggerating) and I've still not gotten any new trophies. I have about 530 trophies right now, but still need around 70 more to beat the 600 trophy challenge.
I know there are more trophies to collect since they appear on the Trophy Shop, but I only want to start getting them through there until I'm certain there's no other way to get them.
