Drafts dont pay out sadly. I remember in 18, I won 42 drafts ( played mostly drafts the entire FIFA), the only good pull I had was IF or SIF Depay who was going for 110k (cant remember excatly).

Draft is a great mode since the gameplay was always better there than in other modes but the reward system is total garbage. You pay 15k coins, you win 4 games in a row and in the end mostly you dont even get the 15k you have paid back. You should get a draft token as a reward for winning the thing and some packs (based on luck you either pack something and make great profit or you just get 5k from quickselling), that would actually be worth it.
