Champ Fury?

I’ve got 2 Fury covers in my rewards queue and Fury waiting to be champed. It’ll cost me a good 300k iso to prevent those covers going to waste. Is he worth it? Or would I be better off saving the iso for someone better?

For background, I’ve got 14 champed 4*s, mostly top tier.

With 14 already champed I’d say go for it. He’s solid when boosted and well you have the extra covers might as well not waste them.

I’ve also got an IW with a spare cover I could champ instead. I haven’t been that impressed with her post-buff, but she might be better than a nearly as old, unbuffed Fury?

I’ve also got a couple much better 4*s that are close-ish, but not really impending. Those being a 0/5/5 Nova and a 5/0/4 Punisher. I’m tempted to just hoard for them.
