Which 4* Next?

My Roster

Quick Question: Wasp, Gwenpool, Blade, an older 4*, or save for Carol?

Long Version: I’m slowly but surely getting all the 4s up to champ and my 5s are still not covered enough to be fully viable (well, Surfer is getting there, but it’s Surfer). I’m sitting on 26 champed 4*s, but since the change to draw rates I’ve got a ton of characters covered and my champs aren’t getting many levels. So who to hit next?

Wasp and Gwenpool are covered. I like Wasp a little more, but she’s about to rotate out and I have a cover for Gwenpool sitting on the vine.
My Blade is 1 cover away from being covered, but I haven’t had much experience with him (all 3 of the red covers I got I pulled after the last PVE).
And I’ve heard people singing the praises of Carol, erecting statues of her as the new Queen of PVP. I’m 2 covers away from getting her up and running. Is it smarter to sell the Gwen cover and bank up to max her ASAP?

And then there’s the forever trio: Fury, Falcap, and Bucky. I’ve had the three of them covered forever, and now that they’re out of pull rotation is there a point to champing them ever?

With 26 champed 4*s, it shows you are playing the long game so I would keep with it. Champ Gwen since you have the cover. Then hoard CP/LTs until you build back up the ISO to be within champing the next one that comes up. Carol is good but I don’t think she will completely invalidate the rest of your roster.

My plan for vaulted 4*s at this point are only champ them if I somehow get more than one cover and have the spare ISO lying around for that exact reason. We have a whole new moving target with the vaulting system so I just don’t see ever having the ISO for it.
