For a lot of players, making coins may be a struggle and I hope this helps! This method should last for a lot of the year and you should make a good amount from it!
Step 1. Snipe any ovr gold cards for 400-650 coins each! Filter by 70-75->Core Gold->All Defense, All Offense, and by all the positions.
Step 2. Go to sets! Exchange->Team Items->Alternate Defensive
Step 3. To do the Alternate Defensive set, you need 10 70-79 OVR cards! So it costs you around 4,500-6,500 coins each time you want to do the set.
Step 4. In the set, there are 5 playbooks you can pull (Cover 2, 4-3, 3-4, Multiple, 46). If you pull Cover 2, 3-4, or 4-3 you will lose around 4,000 coins because you can only sell them fro around 1,500 coins. If you pull 46 or Multiple, you can sell those for arond 24,000 each!
The Math: You have a 60% chance each time to lose 4,000 coins! You have a 40% chance each time to make 22,000+! So mathematically if you do the set 10 times, you would spend around 50,000 coins and you would make back on average 85,000 each time which is a profit of around 35,000 each time you do it! PLEASE CHECK PRICES OF THE MULTIPLE AND 46 PLAYBOOK BEFORE DOING THE SETS!
