ill take the gamble on the tranny. negotiations are shady as you have to pay up a BIG AMOUNT (if youre a 35T) to some shady guy under some shady table

heres some tips from me

avoid the early days of the tranny, i usually wait til the 2nd week
build your team for next season mid season (hope you understood that)
save up skill points unless youre having trouble with your goal

trannys usually dead mid season. i place lots of 1 token bids and end up winning around half of them. i only bid for 5* players
