Spider-Woman, Bl4de, or Carol?

My Roster:

So here's my conundrum: I have too many covered 4*s and not enough ISO. I got into the habit of cracking tokens and spending CP as fast as I could get it back when you could pull any 4* from LTs, since I have so many champed I figured odds where in my favor of adding levels and getting them stronger. Now I've got 8 4*s fully covered and another 3 only one cover away.

Up until now I've been letting the RNG gods guide my roster, leveling whoever I had the most covers for, but now I'm finally at an impasse.I have 3 Bl4de covers and 4 Spider-Woman covers on the vine. I'm 99% sure I'm not going to get the ISO needed to champ Bl4de before his first cover expires, so realistically I'm looking at 2 Bl4de covers and 4 Spider-Woman covers. Spider-Woman is alright, I like Bl4de a bit more, but I'm not tripping over myself to get either champed. I have more SW covers now, but she's going to rotate out soon. Less Bl4des now, but he's going to stick around a bit longer.

And then there's Carol. I had to dump some ISO into her for the recent Crash and holy cow she's good. I mean I'd heard she was good, but that's a fantastic power set. Thing is I don't have any covers for her, maybe 1 cover if I push myself in Stranger Things.

I also have Fury, Mr. F, Falcap, and Bucky cover, add Moon Knight from re-supplies in a couple of weeks, but none of them feel as pressing as the trio I have up front. Thoughts? Also will it ever be worth it to go back for Fury, Mr. F, Falcap, or Bucky?

In the same place as you really. Have 2 SW covers dying but also have 1 carol too. SW is gonna be in tokens for another season and Carol for much much longer. Nevertheless, carol will be of much more use than SW in the long run. 

Would great for a double iso event be great right about now.

Carol is definitely the priority there, followed by Blade. His red when boosted is absolutely insane and his aoe isn't too shabby either. Spiderwoman is more of a niche character, imo, and her red is just too expensive to reliably get off most of the time.
