Training points are very important in MUT. You need training for power ups, abilities, packs, and many other things. Here is a way to get UNLIMITED training points for free!
Find the cheapest training on the market and buy it. For the example here, I will use an 89 overall.
Step 1-Buy training points for the cheapest training you can find! I will be using an 89 for this example. An 89 costs roughly 29,000 coins and quicksells for 3,150 training points.
Step 2-Go to the AH and find a team playbook that sells for over 2,400 coins! The more expensive the playbook you can find, the better this will work. (NOTE: Alternate playbooks will not help for this method! Find a team playbook!)
Step 3-In the store, if you go to the "training" tab, you will see 2 training packs for 150 training points each. Those are where you can purchase the playbooks you saw earlier on the AH that sell for above 2,400 coins! You want to purchase the pack as many times as it takes you to make up for the origianl card you bought for training! For example, since I got a 89, I would buy the pack around 12 times! 12 packs x 150 training =1800! With 1800 training, I made back all the coins I spent on the 89! I am now left with 1350 training points that are completly FREE!
I hope this helped you make some training! Let me know below if you try it and how it worked out for you!
