So I am building my first theme team GB/Ten, very excited about it. I have maxed out my Packer players (they are the 40) and have now started to purchase Ten players for the 20, but I'm showing there are only 53 total roster spots so I'm confused on how to make it to 40/20. Please help. I have the team affinity card that grants me 3 extra spots, and I noticed that team builder cards allow you to use more than one chem on a particular card. Is this the only way to make it to 40/20? Am I missing any other ways to get those chems up to establish my 40/20 team. Your help is greatly appreciated. :-)
