I think I opened up just under or around 100 SM Packs today, that I got from my pledge, and I'm already beating the odds with just under half my packs left (500 packs ≈ 1.66 GFL), 249 Packs remaining to open. I can't complain and I'm rather happy with the things that I have recieved so far.
No, I do not know why/how or if there is something I did lol. If I knew, surely I'd be using it!
Luck onwards and upwards!
