You get an actionable TB from one of the passes for doing all the affinity sets 😎👍
I suggest doing them since they are big exp and good rewards for no effort.
You don’t get cards for completing solos anymore. They’ve moved to an objective based system where you have to grind out stats.
If you complete all the team affinity objectives, I think that’s what it is, you get an 84 team builder fantasy pack
I’m a bit confused on which solos give you those team builder rewards.
