TOTW Schedule advice?

I have 4 x 83 TOTWs including this weeks “free” 1. My question is, when do we think the OVR change happens from 83s and 1 x 86 to 84s and 1 x 87

I want to make an 86 before I can’t anymore and not sure when to get another and pull the trigger. I’m not sure Mack is it - my RH wing slot is stacked this year and since Mack will surely get better cards quickly I’m not convinced.

I’m interested to get other people’s opinion on how many more weeks I’ve got left before I’m stuck and the 83s are only good enough for a SOTM. I’m guessing we see a TOTW OVR upgrade when season 2 kicks off but it’s just a guessing game!

• Also, this evenings event OVRs will give an indication on OVR progression I guess! Just wondering what people think!
