well when the patch came ut i lucked out and got a exp pass for 10 uses i finished using it and i found a glitch for it it also works for gp
1)get a gray hisec case
2)get a gray hisec key
3)get lucky and get a exp pass 100% or gp pass 100%
4)use it up
5)when u get message your gp pass has expired would you like to buy a new one hit yes
6)leave black market
7)play 1-3 games
8) g to equips for black market it should come back for one use
Keep doing this to keep a exp/gp pass till it gets patched!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
