What next

i have 5 4* characters champed. But only 3 of my 2* are champed now and I have 8 3* to champ still. I have 1 4* at 13 covers and 2 more at 12.
Should I save my ISO or rebuild my farm and fill out my 3*s?

I’m in a pretty similar place with my 4*, but I’ve also been tending my farm and filling out my 3*. I find I really get a lot out of those Champ rewards, and if you follow all the way through with the 2* and sell them off, it’s a fairly minor ISO drain in the long run.

Which 4* is it? If you have any reasonable expectation of getting a 14th cover for it in the next two weeks, save up your Iso to champ it. Otherwise, I’d bring up the remaining 2*. 2* covers roll in constantly, and putting every cover to champ builds you more resources. 3* acquisition is much slower, so selling a cover or two isn’t as impactful as sacrificing a 4* or a half dozen 2*.

It is 4* fist. I rebuilt my 2* farm mostly. I got a new cover for him so I am trying to hoard the ISO now. Rebuilding the farm has really helped a ton though.
I hate to not champ him but I missed out on a extra cover for gwenpool and did not get her champed for the cover expired and have not seen another.
