Investment: RTTK Manafá
RTTK 1 goes out of packs today. Manafá is nearly discard (quick sells for 10,004 coins). I think he will rise leading up to their next match on November 3rd against AC Milan considering Porto already has 1 win for the upgrade.
RTTK Manafá: PS4 11k XBOX 11k PC 11k (2-3k profit target)
Sell when you are happy with the profit, and get out before their match on November 3rd.
